Introduction (Continued)

DENSITY4/5 IntroductionThe DENSITY4/5 is the new density meter available from Reichert and designed for fast and reliable measurement of relative density and concentration of fluid samples. It is designed for continuous density measurement in a broad range of applications and has a sealed measurement system with the flexibility to measure the density for many fluids.

The Reichert DENSITY4/5 insures a consistent manufacturing process for you and allows tighter toleranc-es on the results, reducing costs and increasing the quality approvals. For performance and quality choose the Reichert DENSITY4/5.

Reichert introduces the DENSITY4/5 based on the well known principle of the oscillating tube sensor. High precision and reproducibility combined with simple and error free operation classifies the DENSITY4/5 in the field of high performance density meters.

The DENSITY4/5 is manufactured according to the worldwide known Reichert quality, where the unit is fully tested and manufactured for long life and durability. This instrument is compatible with many different reference alcohol tables, has very good precision density resolution, and can be used with a wide range of fluids that will solve the most challenging applications. In addition, this instrument has a built-in moisture sensor, an air pressure sensor and a very accurate temperature control system for extended usage in diffi-cult environmental conditions. Intuitive user friendly software with a large color-TFT touchscreen interface reduces the setup times for protocols and adds powerful troubleshooting capabilities.

Common accessories and robust exchangeable fittings reduce installation expense and saves times to evaluate 3rd party fluids. The DENSITY4/5 can be combined with other Reichert instruments, such re-fractometers, which allow this instrument to be used for complex analysis. This unique modular capability combined with advanced electronics design sets a new standard for density measurement and makes it possible for a quick and easy, on-site change of the measuring cell possible.

Definition of Density

DENSITY4/5 is a characteristic feature of all substances and is defined as mass per unit volume:

p = mV___ p = density

m = massV = volume

In general: The volume of gases, liquids and solids depend on temperature and pressure!

Most substances expand with increasing temperature, but density decreases with increasing temperature (example: Mercury-Thermometer).

Note: It makes a difference whether you measure the mass of an object in air or in vacuum: Weightmeasuredinvacuum→“TrueDensity”(Truedensityofair:1.2kg/m³) Weightmeasuredinair→“ApparentDensity”(Apparentdensityofair:0kg/m³)

Definition of Density (continued)

“SpecificGravity”(SG)(or“RelativeDensity”(RD))isexpressedinmultiplesofthedensityofsomeotherstandard material, has dimensionless quantity, and usually refers to water or air.

SG= P sampleP reference__________

Oscillating U-Tube

The DENSITY4/5 has a built-in reference oscillating U-Tube, which is a new method of measuring density. Approximately 1.0 ml of sample is needed for a measurement and the device offers very high accuracy and resolution. Working with an oscillating U-Tube is ultra fast compared to other methods and true density is provided in the measurement. the system is fully automatic (calculations not necessary), so it is less vulnerable to human error.

The oscillating U-tube samples the viscosity of a fluid by vibrating a glass tube at a frequency which will measure the resistance of a fluid that is being deformed by either shear stress or tensional stress. This sometimesisreferredtoasthe“thickness”ofafluidandithasthefollowingparameters:

• Highviscosity→densityover-reading• Lowviscosity→correctresult

Another parameter to consider in the measurement process is the temperature of the fluid. The tem-perature of the fluid is very important. The built-in high accuracy temperature sensor guarantees precise measurement utilizing a Peltier-Element (temperature range 5°C to 95°C) to control the fluid temperature.

Some features of the temperature control system are:• Eliminates temperature drift. After modifying the measuring temperature, the instrument

remains stable as soon as the new temperature is reached.• Simplifiesmeasurementatdifferentmeasuringtemperatures.Using the temperature con-

trol at 20 °C provides consistent data related to one temperature.

(additional adjustment at 40 °C and 60 °C can be performed. for example, once a year to re-adjust tem-perature characteristics of the DENSITY4/5 sensor).

By pressing the Reichert logo on the upper left, you will select a menu with information about the software version and the device. By pressing the icon in the upper right, you will select the Main Menu.

You can then connect a filled syringe with the help of one of the provided hoses and adapters and measure the density of a sample.

Before applying any sample into the Reichert DENSITY4/5, make sure that all parts made of PTFE (filling nozzles, adapters) and borosilicate glass (measuring cell) are resistant to the sample.

-continued-

26 1400500-101 Rev. A


Measurement (continued)

The sample must be homogeneous and free of gas bubbles. Suspensions or emulsions may tend to separate in the measuring cell and giving incorrect results. Make sure that such samples remain in the measuring cell as briefly as possible. After taking a reading, clean and dry the measuring cell after each measurement if samples with different chemical compositions are to be measured. For similar samples (similar chemical composition and similar density) replace the previous sample by rinsing the measuring cell with a sufficient amount (10 ml or more) of the new sample. Do not leave samples in the measuring cell longer than necessary. Clean and dry the measuring cell as soon as possible.

Measuring with SyringeEnsure that the syringe you are using is clean and dry. Fill it with a bubble-free sample. To remove the air which is in the syringe, hold the syringe upright and press the plunger down slowly in the direction of the needle until a drop of liquid is pressed out. Connect the syringe and push the sample from the syringe into the device by pressing the plunger down slowly. From now on the Reichert DENSITY4/5 measures and displays the density and other important measurements automatically.

271400500-101 Rev. A

DENSITY4/5 and Universal DisplayBy connecting your DENSITY4/5 to the Reichert Universal Display, you can control the instrument in the remote mode.

Please connect all devices - no matter if it is another measuring instrument, a control unit (e.g. keyboard) or a printer - before you start your Universal Display. A single printer or a keyboard could be connected to any free port, but if you want to connect your Universal Display to the DENSITY4/5 series you need to be sure of the naming of each Serial orUSB port. The Serial Interface port is COM1 internally and the four USB ports are COM 2 to COM 5 (refer to the figure below). If you use them with the Reichert USB / Serial Converter please connect those devices in sequential order (do not skip a port).

Note: The default connection for connecting only the DENSITY4/5 is COM1. If another instrument is con-nected to the Serial port (COM1) then any other sequential serial port may be used with the Serial to USB converter supplied with the instrument.

Cleaning & Maintenance

Cleaning

It is advised to employ a regular and effective cleaning routine and store the instrument under the recom-mended conditions, to guarantee a constant and high accuracy of your measurements.

Cleaning RecommendationsThe correct and careful cleaning of the measuring tube is very important for achieving good results. The oscillator of the DENSITY4/5 is made of high-quality borosilicate glass and should never be cleaned me-chanically. All residues and contaminants have to be removed by rinsing only. Choosing a correct purifier will always make cleaning faster and measurements more accurate.

In most cases you use two purifiers. The first one is the one that actually cleans the cell. This fluid must dissolve the sample. The second purifier must remove the first one. Beware that it does not attack the tube or leave any deposits, as drops of the second purifier will remain in the tube. If, for example, water is used as second purifier, it has to be distilled water to prevent mineral deposits.

If you measure similar samples in sequence and the samples can be easily removed from the measuring cell, it is not required to rinse the DENSITY4/5 after each measurement. In this case a careful rinsing pro-cedure using adequate purifiers must take place after the measurement sequence.

Otherwise if you work with different samples with different chemical properties and these samples are not mixable and/or can not be easily displaced from the measuring cell, it is advised to rinse the DENSITY4/5 after each measurement.

Cleaning ProcessFollow the steps below to clean the measuring cell of the Reichert DENSITY4/5 :

1. First of all you have to fill the first purifier into the measuring cell by using a syringe. To do this, fill the syringe with an appropriate purifier, connect the syringe and push the liquid from the syringe into the measuring cell. Refer to Setting Up the DENSITY4/5 chapter to help you configure the hardware.

2. After that the first purifier should dissolve the sample. How much time is needed depends on how easy the sample dissolves in the purifier. This process may take a few seconds or even some minutes.

3. Now push the first purifier out of the measuring cell. Push air into the measuring cell by attaching an empty syringe and pushing the plunger.

4. Fill the second purifier into the measuring cell to remove residues of the first one now. For filling, proceed as for the first purifier.

5. The next step is to push the second purifier out of the measuring cell. Proceed as for the first one.6. Dry the measuring cell with dry air.7. Finally make sure that no liquid remains in the measuring cell.

If you are not sure cleaning was effective, please repeat steps 4, 5 and 6.

Cleaning & Maintenance (continued)

Cleaning (continued)

Choosing Correct PurifierThe purifier to choose always depends on the sample that is supposed to be measured. The best purifiers are often the solvents of the chosen samples. The following table is giving an overview of which purifiers can be used for which samples.

Sample First purifier Second purifierSoft Drinks Supply water 99.9% EthanolMilk Supply water, enzymatic lab cleaner 99.9% EthanolPetroleum Products Toluene, petroleum naphtha, petroleum ether, n-nonane,

cyclohexane, etc. 99.9% Hexane

Beer and Spirits Supply water 99.9% EthanolWort Warm (supply) water 99.9% Ethanol

For petroleum products a strong organic solvent as a first purifier, e.g. toluene, petroleum naphtha, petro-leum ether, n-nonane, cyclohexane, etc. is advisable. The second purifier is chosen to be able to dissolve the first one (e.g. alcohol, acetone, etc.).

Using a standard laboratory cleaner together with water will improve the cleaning action of the water, but this is not required in any case.

If you use a lab cleaner, always follow the instructions given by the manufacturer. Apply strongly alkaline lab cleaners (pH above 10.5) only very shortly and at temperatures below 25 °C. These cleaners will attack the glass surface during prolonged exposure and are even more corrosive at high temperatures.

Maintenance

The DENSITY4/5 is designed for continuous operation, but regular maintenance is advised. Please re-move the liquid from the cell during longer disuse of the instrument. Rinse the cell with a lot of distilled water and blow them dry with Rinse pump for approx. 2 minutes.

Maintenance IntervalsIt is appropriate to extract the unit from the power supply to clean it. To ensure safe operation of the device, it is advisable to send them even without the occurrence of errors to service every two years to get the best performance guaranteed.

Maintenance WorksThe best way to inspect the device is to remove it from the power supply. It is advised to clean the device after removing. If any deviations are higher than the specified values, please contact the Reichert – cus-tomer service.
