2. Introduction

The Vision Microette is a programmable precision syringe-pump sampling instrument that handles a

wide variety of diffusion applications and requirements. The basic instrument consists of 6 sampling

syringes driven by a stepper motor, with internal valve interfacing, in one compact ergonomic

instrument package. Teflon tubing harnesses connect diffusion cell groups to AutoFill™ collectors

for completely automated diffusion sampling.

The Vision Microette can be directed to withdraw an aliquot from a diffusion cell group at a pre-

programmed time. The sample is dispensed into a collection rack that contains vials or test tubes.

The Vision Microette can be programmed to repeat this process multiple times.

The AutoFill is an automated fraction collector designed for seamless integration with the Vision

Microette. The AutoFill includes sample collection capability from six sources, home port array for

waste, all-inert tubing and dispense probes, and reduced tubing lengths to minimize rinse volume

and save time. Collection racks include 16 x 100 mm test tubes for UV, 13 x 100 test tubes for UV,

12 x 32 vials for HPLC, and 12 x 32 vials for UPLC (the UPLC rack holds three trays for Waters

Acquity UPLC).

The Send button allows the user to print the displayed logs to the printer, or upload them to a

USB flash drive. This is a common button on many of the screens of the Vision Microette.

Exit:

The Exit button allows the user to return to the menu. This button is typically located in the

lower right corner of the screen.


After the initialization sequence completes, the unit remains at the home screen. The home

screen displays the syringe position, elapsed test time, and a countdown until the next event.

If no test is running, the times will be listed as 0:0000.

The menu is accessed by touching the Menu button located in the bottom left corner of the

screen. If the Vision Microette is pumping, the status report of the instrument will be displayed

adjacent to the menu button. If the Vision Microette is not pumping, the status report will not

be displayed.

The agitation speed and circulating waterbath temperature can be controlled manually by

touching the RPM|TEMP button located at the bottom of the screen next to the start button.

To change the stirring speed of an individual group of cells, touch the stirrer button for the

group. When the diffusion cells are set to stir, the red indicator will spin. Touching the

indicator will toggle the speed control on or off.

NOTE: The MIXcontrol (silver) stirring control should have the switch on the back in

the on (I) position and the display off so the unit is in sleep mode. Touch the power

button on the front of the MIXcontrol to toggle the system between on and sleep mode.

If the MIXcontrol display is on, it will not respond to commands from the Vision

Microette.

temperature of the circulating waterbath is displayed to the right of the Set Temp button.

The Start button is located on the bottom right of the screen and is used for starting tests.

The time and date of the system are displayed next to the RPM|TEMP button.

If a protocol is already loaded, the protocol name will appear in the upper left corner of the

screen, and when touched it will be opened for editing. If no protocol is loaded, Select

Protocol will appear in the corner; when touched, the Vision Microette will allow the user to

select a protocol for testing.


If security features are enabled, the current user is displayed in the upper right corner of the

main menu screen. If no user is logged on, and security features are enabled, Please Log In

appears in the corner. If security features are not enabled, a user can log on by touching the

same corner of the screen. Security Off appears in the corner of the screen and when the

corner is touched, the Security Configuration screen appears.

The main menu provides access to all the functions of the Vision Microette. To return to the

home screen, touch the bar at the bottom of the menu with the house icon.

4.10 Security

The Vision Microette can be configured to require users to log in and allows for tracking of

any changes made to the protocol. The security system allows for two levels of users

(managers and operators) and can accommodate up to 25 users.

Managers are given full access to the unit and allowed to make any changes to the system

as required, with all of these changes being tracked by the software. All users can be

configured as managers for full control of the Vision Microette.

Operators are permitted to run tests but are not allowed to make changes to protocols or

other system settings. Not all users can be configured as operators; the software requires at

least one user be configured as a manager.

To configure security settings, begin by selecting the Security button from the main menu

and the Security Configuration screen will appear.

Status: Enables or disables the security feature.

Inactivity Timeout: The amount of time without user input before the system requires

a user to log in. The range is 0 to 1:00 (hh:mm). Entering 0:00 disables the timeout

function.


Only managers can display the User List. The users are listed alphabetically and displayed

in groups of 5 per page (4 groups of 5) over 2 pages within the interface. Maximum 25

users.

To select a user, first select the group the user is in.

Select the user from the list that appears.

When the user is selected, the following can be changed:

Name: The name of the user.

Type: Toggles the type of user. The options are operator or manager; the default is

operator.

Status: The user's status. The options are locked or unlocked. An unlocked user has

access to the system, a locked user does not and must be unlocked by a manager.

On the Security screen the following options are available:


Config: Allows access to the Security Configuration screen.

Archive: Allows the manager to use backup or restore functions as follows:

Backup: Allows a manager to create and send a backup of the instrument’s

security configuration (including the users and corresponding profiles) to a flash

drive in the USB port. The security configuration is in a single file under the

filename security.bak.

NOTE: The Backup function will overwrite all users previously saved on the

flash drive.

Restore: Allows a manager to restore the instrument’s security configuration

(including users and corresponding profiles) from a flash drive in the USB port from

the security.bak file.

NOTE: The Restore function restores only user profiles from the backup file,

but clears all users' passwords. All other users (not in the backup file) will

be erased.

Password: Allows the user who is currently logged in to change their password.

Add: Allows a manager to create a new user. The screen that appears is identical to

the Edit User Profile screen.

Log Out: Logs out the current user.

With security enabled, a user can log on either by touching the upper right of the home

Additionally, if any other input is attempted, the Vision Microette will prompt the user to

log in.

The installation of the Vision Microette is now complete.


5.1 How the Vision Microette Works Before beginning operation of the Vision Microette, the operator should have a thorough

understanding of how sampling is performed and how this may affect method development.

While dissolution sampling involves withdrawing a sample and then possibly adding

replacement media, the Hanson vertical diffusion cell is sampled by pushing the sample out

with new media. This is done under specific conditions in order to avoid diluting the sample.

1. The stirrer is stopped 30 seconds prior to the sample point. The syringes also load fresh

receptor media from port D.

2. New media is slowly pumped into the cell through the replace port at a rate of 1.2

mL/min.


3. This results in the diffusion cell becoming pressurized.

4. The sample is pushed out the sampling port to the AutoFill.

Because the fresh receptor media is pumped in slowly, it does not mix with the existing media.

In order to ensure sample volumes are accurate, Rinse and Collect delays are used, which

keep the needles in place to allow time for the pressure within the cell to equilibrate. The

sample will always follow the path of least resistance. In a properly working system with

sealed diffusion cells, this will be the sample port out to the AutoFill. If the diffusion cell is

leaking, the sample will find another way out.


In some cases, it will be obvious that diffusion cells are leaking. In other cases, the leak may

be harder to find. The typical symptoms of a leak are:

Fresh media appearing around the diffusion cell during a test

Sample vials are empty or not filled to the correct volume

AutoFill needles drip between sample points

Typical causes of diffusion cell leaks are:

Irregular or rough membranes, which prevent the cell from sealing

Membranes that flex during sample points, resulting in leaking

Insufficient amount of material on top of membrane, which causes the receptor media

to be pushed into the donor chamber

Clogs in the tubing between the sample port and AutoFill needles

NOTE: Anything that increases the pressure inside the diffusion cell can potentially

cause a leak. This includes increasing the delivery speed of the Vision Microette.

With this style of sampling, it is also important to maintain control of the volume entering the

diffusion cell. If the cell is overfilled during a test, fresh media may be pushed into the AutoFill

lines, which will dilute the sample. The following table lists the volumes of media which can

be pumped into the diffusion cell without unintended dilution of the sample.

Cell Volume Maximum Amount Pumped

Without Dilution

4 mL 2.0 mL

7 mL 2.5 mL

12 mL 5.0 mL

Figure 5.1 Maximum Amount of Volume Without Dilution Table

NOTE: A 2 ft tubing harness is included to reduce the rinse volume requirements. It is

strongly recommended to use this between the diffusion cells and the AutoFill.

Every day: The alarm occurs every day.



entered 30 days, the alarm would occur once every 30 days. The range is 2-1827

days.


MonSat: The alarm will occur every Monday through Saturday.

The Edit Time/Date screen is accessed by touching the Time/Date button located along

the bottom of the Edit Alarms screen. It allows the user to set the time and date on the

system.


The System Date format is displayed as DD-Mmm-YYYY where DD is the day (01-

31), Mmm is the current month (Jan – Dec), and YYYY is the year in the long format

(2009-2999). Enter the date numerically, using the format DD-MM-YYYY.

The System Time format is 24 hour time (military time), displayed as hh:mm:ss

(hours:minutes:seconds). Enter the time in hh:mm format, where hh is the current

hour (00-24) and mm is the current minute (00-59).

NOTE: The system clock is powered by a capacitor. If the system is left

unplugged for 2 weeks, then the time and date will have to be reset. The system

must be plugged in at least 5 minutes for the capacitor to reach sufficient charge

to maintain the time and date when the system is powered off.

5.7 Tools

Touching the Tools button opens the Automatic Syringe Control menu. Other options

include: Manual Syringe Control menu, Collector menu, and Remote Command screen

Control menu.

The Automatic Syringe Control screen allows the user to execute procedures with a

moderate level of automation and is accessed by touching the Auto button at the bottom

of the screen.


If a diffusion cell group or media is not configured to a particular port, then it will not be

possible to utilize it using the Automatic Syringe Controls. If material must be transferred

to an unconfigured port, refer to the Transfer command under Manual controls. The

following tabs are available for Automatic Syringe Control.

Sample: This allows the user to sample the specified volume from the specified cell

group. The source for this function is always port D.

Collect Volume: The sample volume to transfer (0.0- 99.9 mL). The recommended

maximum capacity of 16 x 100 test tubes is 15 mL and 12 x 32 HPLC vials is 1.5 mL.

Target: The diffusion cell group from which the sample is collected. This can be set to

A, B, or C.

Target Row: The collector row to which the sample is delivered. This is a numeric

value that depends on the type of collector rack used.

Dispense Speed: The speed at which the syringes dispense the media. Slow

(default) dispenses the syringes at 1.2 mL/min and is appropriate when working with

assembled diffusion cells. Fast will dispense the syringes at 9.9 mL/min and is

appropriate when working with diffusion cells when the cell tops are removed.

Prime: Allows the user to prime the lines and fill the diffusion cells before starting a test.

This function should only be used when the cell tops are removed. The system will pump

at the fast speed (9.9 mL/min) and is likely to cause leaks in an assembled diffusion cell.


Prime Volume: The amount of volume to be transferred. This can be set from 0 mL to

99.9 mL using the numeric keypad.

Source: Toggles the port from which the material is pulled. This will typically be set to

D for clean media.

Target: Toggles the port to which the media is delivered. This can be set to A, B, C or

ALL diffusion cell groups.

Repeat: Allows the user to enter the number of additional times to implement the

transfer. This can be set from 1 to 9999. For example, if a volume of 10 mL from

Source D to Target A with a Repeat of 2 was selected, the Vision Microette will

transfer 10 mL from D to A twice, for a total of 20 mL.

Rinse: Allows the user to rinse the sample lines in preparation for collection of a sample.

The system will pump at the slow speed (1.2 mL/min) and is safe to use on sealed

diffusion cells.

Rinse Volume: The amount of volume to be transferred. This can be set from 0 mL to

99.9 mL using the numeric keypad.

Target: Toggles the port to which the media is delivered. This is typically set to A, B

or C for diffusion cell groups.

NOTE: The source for the Rinse function is always D for fresh receptor media.

The Manual Syringe Control screen is accessed by touching the Manual button at the

bottom of the screen. The Manual Syringe Control screen allows the user to execute

basic controls over the Vision Microette syringes. These functions are primarily used for

maintenance and troubleshooting of the system.

Transfer: Allows the user to transfer a programmed volume of media from a source port

to a destination port regardless of whether the port has been configured. The transfers

are executed at the full pumping speed of 9.9 mL/min. It is recommended to only use this


with open diffusion cells, as sealed diffusion cells may leak due to the sudden increase in

pressure.

Volume: The amount of volume to be transferred. This can be set from 0 mL to 99.9

mL using the numeric keypad.

Source: Toggles the port from which the material is pulled. This will typically be set to

D for clean media.

Target: Toggles the port to which the media is delivered. This is typically set to A, B

or C for diffusion cell groups.

Repeat: Allows the user to enter the number of additional times to implement the

transfer. This can be set from 1 to 9999. For example, if a volume of 10 mL from

Source D to Target A with a Repeat of 2 was selected, the Vision Microette will

transfer 10 mL from D to A twice, for a total of 20 mL.

Load: Allows the user to load the specified volume from the specified source. After this is

executed, the Vision Microette will stop and await the next command. Volume for the load

command is restricted to the maximum amount the syringe can hold, 2.5 mL.

Dispense: Allows the user to dispense the material in the syringe to the selected target.

If dispensing to Target A, B or C, the needles of the AutoFill are automatically lowered, but

the user must ensure that the needles are located over the proper row in order to avoid

spillage. Dispense is executed at the full pumping speed of 9.9 mL/min. It is

recommended to only use this with open diffusion cells, as sealed diffusion cells may leak

due to the sudden increase in pressure.

Valves: Allows the user to open and close the valves located within the unit. Touching

the red button located next to each port letter will open the valve for that port.


Touch Collector at the bottom of the screen to pull up the Collector Controller Menu,

which controls the AutoFill.

The Collector Controller Menu will display up to 3 tabs on the left side of the screen. Each

allows control of a different collector. Each collector corresponds to an installed diffusion

cell group.

This menu displays the following positions:

Rack: Displays the rack that is currently installed in the AutoFill.

Row: Displays the current row where the dispense head is located.

NOTE: The Home position (last row in back) is also the Waste position. The next

row (toward the user) is the Wash position. The next row forward is Row 1,

where the rack begins.

The following functions are available in the cross-shaped menu:

Home (center): This button raises the needles and moves the dispense head to the

Home (Waste) position.

Needles Up (top): Moves the needles up while keeping the dispense head in the same

position.

Needles Down (bottom): Moves the needles down while keeping the dispense head in

the same position.


Move Back (left): Moves the dispense head 1 row closer to the home position, toward

the back of the AutoFill.

Move Forward (right): Moves the dispense head 1 row forward from the home

position, toward the front of the AutoFill.

Other options, to the left of the cross-shaped menu:

Initialize: Performs an initialization of the collector by executing a soft reset on the

AutoFill. This also returns the dispense head to the home position.

Goto Row: Directs the AutoFill to move the dispense head to the specified row.

Service Position: This appears when no rack is installed in the selected AutoFill.

Touching this button will move the dispense head to the front of the AutoFill to allow for

cleaning and service of the system.

The Remote Command screen is accessed by touching the Control button at the bottom

of the screen. The Remote Command screen provides access to the Vision Microette and

AutoFill service and support functions. The button for this screen does not appear to

operators if security features are enabled.

NOTE: The Remote Command Screen should only be used when instructed by

Hanson Research technical support.


5.8 Protocols

Protocols can be accessed by touching the Protocols button on the main menu.

It can also be accessed from the home screen by touching [Select Protocol] (or protocol

name) displayed in the upper left corner of the screen.

Protocols are a list of parameters and events that are required to perform a diffusion test.

These parameters can be modified to accommodate user needs. Up to 100 different

protocols can be stored.

The Recent tab displays the protocols which were used most recently.

The Page # tabs display the protocols in alphabetical order based on protocol name.

The protocols are listed alphanumerically by protocol name in groups of 5 (4 groups per page)

over 5 pages within the interface.

Buttons on the right of the Protocol screen are:

Checksum: This button generates a unique checksum for the protocols. This can be

used to ensure a restored set of protocols is identical to the original set. When touched,

the Protocols check pop-up is displayed, which first informs the user the value is being

calculated, then displays the calculated value.


For example, an operator touches the Checksum button and obtains a value of 0EA4.

The operator then changes a protocol label by 1 character. When the operator

touches the Checksum button again, it will generate a different value.

This feature can be used to ensure that backups and restorations of protocols are

identical to the originals. The feature can also be used by managers to ensure that

protocols have not been changed without authorization.

Archive: Allows Backup and Restore functions.

Backup: This button allows all existing protocols to be saved on the flash drive,

which must be inserted into the USB port to the left of the touchscreen. When this

button is touched, the Protocol Backup pop-up is displayed, which prompts the

user to insert a flash drive into the USB slot if it is not inserted. If the flash drive is

already inserted, it writes the protocols to the drive and the pop-up disappears. All

protocols will be saved to a file named mproto.bak.

NOTE: Existing backup files will be overwritten on the USB flash drive.

Restore: This button allows protocols to be restored from the flash drive inserted

into the USB port. All protocols will be restored from the mproto.bak file.

NOTE: The restore function will produce an exact copy of the protocols on

the flash drive. All existing protocols will be overwritten.

If the mproto.bak file does not exist, then a pop-up error message is

displayed and the message is also written to the error log. The message

asks the user to confirm protocol restoration. If the user touches No, then

the protocols will not be restored. If the user touches Yes, all the protocols

will be overwritten.

Import: This button allows the user to import all previously exported protocols from a flash

drive inserted into the USB port. Protocols must have been previously exported to the

flash drive in order to import them. Only protocols with differing protocol names will be

added. Existing protocols may be overwritten if the user confirms an overwrite; otherwise,

the existing protocols will remain.


Term Used for Existing Protocols/Users Data sent

Backup All protocols or users Overwritten Writes to USB drive

Restore All protocols or users Overwritten Copies from USB drive

Export Single protocols Kept Writes to USB drive

Import Single protocols Kept (or overwritten as

directed) Copies from USB drive

Figure 5.2 Summary of USB Transfer Functions Table

Add: Allows the user to create a new protocol.

To select a protocol, first select the group it is in.

Select the individual protocol on the screen. The revision date of each protocol is displayed

and cannot be directly edited. If security features are enabled, the last user to edit the

protocol is displayed.


Once you have loaded or created a protocol, buttons on at the bottom of the Protocol screens

will appear. These are:

Export: Exports the open protocol to a USB flash drive. The exported protocols are

saved with a .hmp extension.

Copy: Creates a copy of the loaded protocol for the user to work on. The copy is

immediately loaded for editing.

Delete: Deletes the open protocol.

Print: Prints the selected protocol.


Tabs available on the Protocol screen are Labels, Diffusion, Sampling, and Events.

The Labels tab provides the user a place to list the protocol name as well as other

information on the protocol.

Protocol Name: This is the name of the protocol and must be unique. The

Protocol Name is how the protocols are organized on the protocol selection

screens.

Comments: Allows the user to add any notes specific to the protocol.

The following field names can also be edited by the user though the Configuration

settings, in the Edit Titles screen.

Drug Name: The name of the drug the protocol is designated to test (e.g.,

hydrocortisone).

Dosage: The dosage size of the drug to be tested (e.g., 300 mg).

Protocol ID: A secondary ID for the protocol; this does not need to be unique.

Membrane: Lists the type of membrane used for the diffusion protocol (e.g.,

polysulfone, mouse skin).

Media Type: Lists the type of receptor media used for the diffusion test (e.g., water,

30% ethanol).

Media Volume: Lists the approximate volume of the diffusion cells used for the test

(e.g., 4 mL, 7 mL, 12 mL).

The Diffusion tab provides information and settings for the diffusion cell groups. If a cell

group is unsupported these values are for reference only.


Stirring Speed: The target drive speed for the diffusion test. The parameter is

rpm, and the range is 0, 100-2000 rpm. The stirring control only recognizes

increments of 10.

NOTE: Only set points in increments of 10 will be recognized by the stirring

control. If a speed is entered that is not in an increment of 10, it will be

rounded lower. For example, if a user entered 326, the stirrer would run at

320 rpm.

Temperature: The target temperature of the diffusion cells. Range is 0, 25.00 -

55.00 °C.

Test Length: The total time of the diffusion test. Range is 0-999:00 (hh:mm).

Print Interval: The interval at which the diffusion test system status (speed,

temperature, etc.) will be printed. The range is 0 to 999:00 (hh:mm). If the user

does not wish the status to print the Print Interval should be set to 00:00.

Temperature Tolerance: The tolerance for the temperature in the waterbath. The

recommended value is ± 0.5 °C. Range is 0 (off), 0.10 to 5.00 °C.

The Sampling tab allows the user to select the sampling mode and specify all the parameters

related to sampling.

Rack Type: The type of rack used for sample collection during the test. 16 x 100, 13 x

100, 12 x 32 (default), and 12 x 32 UPLC.

Rinse Volume: The amount of volume pumped before collection occurs. This value

should be large enough to remove old sample from the sample lines, but not so large as to

dilute the new sample within the diffusion cell. The range is 0-99.9 mL.

NOTE: Refer to section 5.1 on the amount of media volume that can be removed

from a diffusion cell without diluting the sample.


Collect Volume: The volume collected into test tubes or vials during a sampling cycle.

The range is 0-99.9 mL. The maximum for 16 x 100 test tubes is recommended to be no

more than 15 mL; for 12 x 32 vials, no more than 1.5 mL.

Cell Group Offset Time: This determines the offset between the diffusion cell groups

when running multiple diffusion test systems. The minimum recommended value is 0:05

minutes. The range is 0:00 to 1:40 (H:MM).

Pre-Start Rinse Time: Allows the user to set the Vision Microette to start the pumping

ahead of the scheduled sampling time to allow for fine-tuning sample points. The range is

1 to 3600 seconds (1 second to 1 hour).

The Events tab allows the user to add events or modify the Event Table.

The Event Table is a sequence of up to 50 events that will take place at user-programmed

times. There are two types of events: sampling and remote commands. Sampling events

must have a time assigned. Remote command events may occur during the test, pre-run

(before the test), or post-run (after the test).

NOTE: Pre-run and post-run events cannot be sampling events.

Pre-Run: Events programmed as a pre-run event will occur before the test begins. For

example, an operator programs a pre-run event of Stirrer Speed for 200 rpm. Prior to the

test starting, the stirrers will spin at 200 rpm. When the test begins, the motor will go to

the speed programmed on the Diffusion tab.

Post-Run: Events programmed as post-run will occur after the test has completed. For

example, an operator programs a post-run event of Bath Temp for 40 °C. Once the test

completes, the circulating waterbath temperature will be set to 40 °C.

To edit or delete an event, touch the field in which it appears; this will open the Edit Event

screen.

To add a new event, touch the Add Event button; the following screen is displayed:


The Add Event screen allows the user to add an event or events to the event table.

Start Time: This defines the start of the first event. The range is 0:00 to 999:00

(hh:mm). Preset buttons are Pre-Run and Post-Run.

Event Type: This defines the type of event that is to occur. By default, all events

are sampling events. Many of these options require the entry of an Event Time.

Here are the event types:

Sample: Collects a sample.

Bath Temp: The parameter is a temperature value. It allows the user to set a new

circulating waterbath temperature.

Collect Volume: This allows the user to set a new collection volume for the test.

Delay: This allows the user to set a delay of specified amount of time. Range 1 to

12,000 sec. Valid for Pre-Run only.

Dispense Flow Rate: This allows the user to speed up, or slow down the dispense

rate of the syringes during a rinse or sample collection. The range is 0.6 to 23.8

mL/min. The default speed when dispensing during a test is 1.2 mL/min.

NOTE: Increasing the dispense rate beyond the default speed will increase the

chance of a diffusion cell leaking during sampling. 9.9 mL/min. should not be

exceeded, or the Vision Microette could be damaged.

Load Flow Rate: The parameter is speed of the syringes while loading. This changes

the speed at which the Vision Microette syringes load material. The range is 0.6 to

23.8 mL/min. The default setting is 9.9 mL/min.

NOTE: 9.9 mL/min. should not be exceeded, or the Vision Microette could be

damaged.

Post Collect Delay: This allows the user to adjust the delay between when the Vision

Microette stops pumping, and the needles of the AutoFill move up out of the vials.


This delay is intended to allow excess pressure in the diffusion cell to bleed off for an

accurate sample volume. The default value is 10 seconds. The range is 0.01 to 30.00

seconds.

NOTE: Decreasing the Post Collect Delay from the default value may result in the

needles dripping, and/or an inaccurate sample volume.

Post Rinse Delay: This allows the user to adjust the delay between when the Vision

Microette stops pumping, and the needles of the AutoFill move up out of the waste

lines. This delay is intended to allow excess pressure in the diffusion cell to bleed off

for an accurate rinse volume. The default value is 10 seconds. The range is 0.01 to

30.00 seconds.

NOTE: Decreasing the Post Rinse Delay from the default value may result in the

needles dripping, and/or an inaccurate sample volume.

Print Interval: The parameter is the interval between printing. This changes the print

interval for printing the status of the diffusion test systems.

Print Statistics: This prints the current statistics for the test. There are no

parameters for this command.

Prompt: The message that will pop up at the event time. Up to 11 characters.

Rinse Volume: This allows the user to set a new sample rinse volume (0 to 99.9 mL)

during the test.

Status: This allows the user to get an automatic status at the specified time.

Stirrer Speed: This allows the user to change the stirring speed in the middle of a

test. The parameter is rpm, and the range is 0, 100-2000 rpm. The stirring control

only recognizes increments of 10. If a speed is entered that is not in an increment of

10, it will be rounded lower. For example, if a user entered 326, the stirrer would run

at 320 rpm.

Temperature Tolerance: This changes the diffusion test system temperature

tolerance for the protocol. The options are 0 (disabled), or 0.1 to 5.00 °C.

Transfer: The parameters are Volume, Source, Target, Position. It allows the user

to transfer a specified volume of solution from a specified source to a specified target.

The following sources/targets are available when using a Transfer command in the

event table of a protocol.

U: This source/target keeps the needles of the AutoFill up. It is useful as a

source to pull air into the syringes to dry out the lines.

W: This source/target lowers the needles into the Wash port of the AutoFill. This

can be used if an operator wants to run a protocol for a custom wash configuration.

H: This lowers the needles into the Home/Waste port of the AutoFill.


1-25: This can be used as a target only. This target will lower the needles into the

corresponding row of the rack. For example, if “10” was entered, the needles

would lower in the 10th row of the installed rack.

A, B, or C: Will keep the collector in the current position when the transfer will

occur. To control which position is used on the collector, add a W, H, or row

number after the target.

NOTE: Using A, B, or C will not lower the needles of the collector when

performing transfers!

Example 1: To perform a 1 mL transfer from source D to group A, row 5 of the

collector – 1.0,D,A,5

Example 2: To perform a 5 mL transfer from source D to group B with the needles

in the Home port – 5.0,D,B,H

Number of Events: This allows the user to set the number of times this event will

occur. By default, only one occurrence of the event is created. For multiple

occurrences, the first event begins at the start time.

Interval Between Events: This allows the user to set the interval between the

events occurring when multiple events are being added to the event table, in the

format hh:mm, where hh is hours and mm is minutes. The range varies depending

on the number of events and the sampling times.

9. The Vision Microette will return to the home screen, and when the circulating waterbath

temperature has stabilized, a pop-up will appear asking the operator to apply the dosage

to the diffusion cells.

10. Sample Preparation – Standard/Occluded Cell Top

For open cell tops, proceed to step 11.

For patches, skip to step 12.

a. Carefully lift one membrane at its very edge with the forceps. b. Blot the membrane on a tissue (Kimwipe). c. Apply the membrane to the bottom of a dosage wafer. d. Place the dosage wafer on the edge of the block, so that the center of the

dosage wafer is fully on the block, but a small portion of the membrane is overhanging. This will facilitate removing the wafer after the gel is applied.


e. Apply a dollop of gel to the dosage wafer on top of the membrane and inside

the wafer cavity.

f. Use the spatula supplied with the diffusion cell system to carefully smooth the

material over the membrane, filling the entire cavity of the dosage wafer.

g. Use the spatula to wipe any excess material from the surface of the wafer. h. Apply the glass disk to the top of the dosage chamber.


i. Using the forceps to apply pressure upward on the membrane, lift the sample assembly (dosage wafer, membrane, and glass disk) off the block.

j. Invert the sample assembly and place it into the cell ring.

k. Set the sample aside with the membrane facing upward until the start of the

test. l. Repeat as necessary to prepare the dosages for each of the cells. m. Ensure that the stirrers are not rotating and there is a positive meniscus

covering the top of each diffusion cell. If media has evaporated during equilibration, it can be added to the diffusion cell with a pipette.

n. Hold the sample assembly between the thumb and forefinger at an angle of 30° to 45°. Place thumb on the edge of the dosage wafer and the cell, and roll the sample assembly onto the top of the cell. It is recommended to have the cutout on the cell ring facing forward so that the membrane can be viewed more easily.

o. Slide the clamps into place. p. Inspect under the membrane (a small mirror is recommended) for bubbles and

to ensure the membrane has not moved.


11. Sample Preparation – Open Cell Top

Skip to step 13 if using standard/occluded cell tops.

a. Carefully lift one membrane at its edge with a pair of forceps. b. Lay the membrane across the bottom of the open cell top. c. Ensure that the stirrers are not rotating, and there is a positive meniscus

covering the top of each diffusion cell. If media has evaporated during the equilibration, it can be added to the diffusion cell with a pipette.

d. Apply the open cell top to the top of the diffusion cell, ensuring that no bubbles are trapped beneath the membrane. Apply the clamp to secure the open cell top.

e. When ready to begin the test, apply a dosage to each of the diffusion cells and then install the cell caps.

12. Sample Preparation – Patch Support Top a. Fill the cell so the receptor chamber is slightly overfilled. This does not need to

8.1 Scheduled Maintenance

After Each Test

Clean the system as per section 6.4.

NOTE: Refer to the wetted materials chart in section 3.6 (Fig. 3.1) before selecting a

solvent for cleaning.

Weekly

Inspect syringes for leaks. Ensure that no air bubbles are entering the syringe from the side

of the plunger. Syringes should be replaced when they have reached 100,000 cycles,

regardless if they are leaking or not. For instructions on syringe replacement, refer to section

8.3.

Every Month

Change or clean water in the circulating waterbath.

Every 6 Months

Inspect sample lines and fittings. Ensure all fittings are tight. Sample lines should be free of

debris, kinks, and breaks. For information on how to remove debris from the lines, or repair

kinked or broken lines, please contact Hanson Research Technical Support.

Inspect AutoFill needles for damage and replace as necessary.

Inspect AutoFill dispense head for smooth motion.

Annually

Replace AutoFill needles.

8.2 General Cleaning

The Vision Microette autosampler and AutoFill collector have been designed to be low

maintenance instruments. In general, the instruments are maintained by wiping clean after

each use. For information on how to clean the sample lines, refer to section 6.4.

8.3 Syringe Replacement

Replace syringe plungers when the maintenance log indicates 100,000 cycles, or as needed.

After replacing syringes, volume calibration should be performed (see section 8.4). DI or

better quality water should be used for this procedure.

1. Remove the front cover of the Microette.

2. Using the autosampler controls, select the manual control option and load the syringe

with 1 mL.

3. Remove the shoulder screw at the bottom of the syringe.

4. Using the autosampler controls, select the manual control option and load the syringe

with 2.5 mL.

5. Gently unscrew the syringe by grasping the barrel and turning it clockwise.


6. Install the new syringe by screwing it in counterclockwise.

NOTE: When the syringe contacts the manifold, turn no more than 45 degrees in

order to ensure a good seal and not damage the valve.

7. Using the autosampler controls, open the valves for any lines.

8. Gently pull the syringe plunger down and align it with the drive bar.

9. Reinstall the shoulder screw.

NOTE: The shoulder screw should be able to be installed finger tight until it is

flush with the syringe plunger. If the screw cannot be turned with only your

fingers, adjust the plunger and try again. Once the screw is flush with the syringe

plunger, it may be tightened with a screwdriver.

8.4 Sample Volume Calibration

Use DI-grade or better quality water at room temperature.

1. Weigh empty sample collection vials or test tubes and record (tare weight). Caps are

required in order to ensure accuracy.

2. Program the autosampler to collect the required the sample volume.

3. Weigh the filled sample collection vials and subtract the empty (tare) weight from the fill

weight. Make any necessary calculations to account for water density.

(g/mL)Density

(g)WeightTare (g)WeightFill(mL) Volume

If the volume does not fall within the specifications in section 3.5, contact Hanson Research

Technical Support.

8.5 Needle Replacement

It is recommended to replace the PEEK needles of the AutoFill annually or as needed.

1. Remove the AutoFill rack.

2. Using collector controls, move the AutoFill to the service position.

3. Gently pull forward and down on the top of the dispense head cover to remove it.

4. Disconnect each of the PEEK needles from the needle block.

5. Secure the dispense head cover.

6. Using the Vision Microette controls, return the AutoFill dispense head to the home

position.

8.6 Cell Volume Calibration

Proper determination of diffusion cell volume is critical for ensuring accurate results. It is

recommended to determine the diffusion cell volume to 3 decimal places.


1. Obtain a sufficient quantity of room temperature water to perform the cell evaluation on all

of the diffusion cells. Measure and record the temperature of the water with an NIST

traceable thermometer. Determine the density of the water.

2. Wrap the circulator tubing around the individual cells and connect the ends together as

shown in figure 8.1.

Figure 8.1 Diffusion Cell with Volume Determination Kit Plug Installed

3. Cut pieces of Parafilm to form small squares that are just large enough to cover the open

orifice in the top of the diffusion cell. If the Parafilm square is too large, or too small,

leaking may occur.

4. If necessary, dry the inside of each diffusion cell, the helix, and the stir bar using lab

wipes, air, heat, or any other appropriate means to dry the surfaces completely.

5. Insert the plug from the cell volume kit into the replace port of the first diffusion cell as in

Figure 8.1.

6. Obtain and record the tare weight of the first diffusion cell.

7. Fill the syringe from the cell volume kit with room temperature water. The syringe should

be filled with at least 1 mL more water than the theoretical volume of the diffusion cell. For

example, when testing a 7 mL diffusion cell, use a syringe that holds at least 8 mL.

8. Remove the plug and attach the syringe to the sampling port for the cell. While holding

the cell upside-down, begin to fill the cell with water. If necessary, rotate the cell during

the filling process so that the air is expelled from the replace port. Fill the entire cell but do

NOT fill the bubble trap.

Figure 8.2 Diffusion Cell Being Filled with Water

9. Place the plug on the replace port and then remove the syringe from the sampling port.


Figure 8.3 Diffusion Cell Ready for Weighing

10. Determine and record the weight of the full diffusion cell and calculate the volume of the

diffusion cell.

(g/mL)Density

(g)WeightTare (g)WeightFill(mL) Volume

11. Repeat the steps so that each diffusion cell has 3 volume determinations. Average the

volume determinations to determine the volume of the diffusion cell. It is recommended

that the relative standard deviation (%RSD) not exceed 2.0%. If the %RSD does exceed

2.0%, check for leaks of the diffusion cell and repeat the evaluation.

8.7 Tubing Volume

Tubing volume can be calculated using the following information.

Tubing Description Locations Volume

(ml/inch) Volume

(ml/cm)

1/16 in. Teflon Tubing

Tubing harnesses, autosampler tubing, collector tubing, sample

harness located on system

0.0126 0.00496

Common Items Tubing Length (in.) Tubing Length (cm)

Vision Microette Tubing on

Source A, B, and C 36 91.44

Vision Microette Tubing on

Source D 36 91.44

AutoFill Tubing 48 121.92

Extension Tubing Harness (3 ft) 36 91.44

Extension Tubing Harness (2 ft) 24 60.96

To calculate the dead volume:

(Tubing length in. or cm)*(mL/in. or mL/cm) + (Tubing length in. or cm)*(mL/in. or mL/cm) and

repeat for each section.


9. Moving and Storage

If the Vision Microette will not be used for a short period of time (3 days or more), the instrument

should be cleaned and the power should be turned off. If the Vision Microette will not be used for

an extended period of time (30 days or more), the instrument should be cleaned, covered, the

circulating waterbath drained, and all instruments unplugged from the power source.

The instrument is heavy and great care should be taken when moving it. If the instrument is moved

to a new location, revalidation should be considered.

Two people are required to lift the Vision Microette and/or AutoFill. Lifting should be done with one

person situated on each side of the instrument. Remove the collection rack before moving the

instrument. Lift the equipment by the base (applies to both Vision Microette and AutoFill).

NOTE: Lifting without assistance may cause injury.
