TYPICAL VALUES OF HEAVY METALS

QUANTITATIVE FILTER PAPERS

Quantitative filter papers are recommended for quantitative analysis. As quantitative analysis requires a high puri-

ty, quantitative papers are washed out with acid.

We offer two grades of quantitative filter papers – ashless and ashless hardened. Our ashless grades are made for

100% cotton linters with an ash content of 0,007%. The ashless hardened grades are made of pure cellulose with

an alpha cellulose content of almost 100%. The ashless hardened grades are wetstrengthened.

QUALITATIVE FILTER PAPERS – low ash

These extremely pure filter papers grade 120H to 5 are produced of pure cotton pulp. Grade 11–20 are produced

with an alpha cellulose content of almost 100%. Types 11–14 correspond in their filtration properties to our

quantitative papers No. 1–4. The ash content for the grade 120H to 5 amounts to about 0,06%. For Grade 11–20

the ash content amounts to <0,1%.

Grade 11 to 14 are wetstrengthened. Grade 15 and 20 are slightly wetstrengthened.

These filter papers can also be supplied as folded filter papers.

GENERAL PURPOSE FILTER PAPERS

These papers are made for general purpose filtration. Their ash content is so low that they can be used for ordi-

nary qualitative filtrations. They are filter papers for a variety of different applications with very different basis

weights. The development of these papers was keyed particularly to their final use. This is documented by the

different surface structures. The papers are made of very pure cellulose with an high alpha cellulose content.

Average ash content of the these filter papers is 0.1%.

BLOTTING MEMBRANES

NITROCELLULOSE has a very favourable combination of high protein binding and low background. If you also

add its ease of wetting you can easily understand its popularity in blotting techniques.

Our 0.2 µm membrane is the standard material for protein blotting. The 0.45 µm membrane is commonly used for

nucleic transfers and colony/plaque transfers.

For multiple reprobing of nucleic acid blots SUPPORTED NITROCELLULOSE (NC-Support) is the best choice as

standard nitrocellulose has a limited physical strength. The polyester support does not have any effect on the

wetting and binding charateristics. NC-Support is also preferred for repeated colony transfers and UV-crosslinking

of DNA.

The POLYAMIDE MEMBRANES are normally used for transfer and immobilization of nucleic acids.

pH determination paper with colour

The theoretical basis for determining pH values

For the chemist, determining the concentation of

hydrogen ions (H+) is of extreme importance, because

the progress, balance and speed of very many reac-

tions largely depend on it.

Hydrogen-ion concentration is also of interest to bio-

logists, the medical profession and to technicians,

because, on the one hand. H+-ions may be involved in

reactions under the physiological conditions in which

biological processes occur, or may act as their

catalysts, and, on the other, hydrogenion concentration

has an important part to play in other areas such as

corrosion, for example.

Applying the law of mass action to the dissociation of

water gives us:

(1) K = [H+] · [OH––]

or (2) [H+] · [OH––] = K · [H2O] = 10–14 (at 20°C)[H2O]

This equation applies to perfectly dilute solutions. Hence, the concentration of hydrogen and hydroxyl ions in

water is 10–7 = 1 n10.000.000

In 1912, Sörensen introduced the pH value as the negative decadic logarithm of the hydrogen-ion concentration.

The following equation applies:

(3) pH = –lg [H+]

The acidic and basic properties of aqueous solutions are defined by the following parameters:

acidic solutions [H+] > 10–7 mol/l; pH < 7

neutral solutions [H+] = 10–7 mol/l; pH = 7

basic solutions [H+] < 10–7 mol/l; pH > 7

GENERAL INFORMATION SYRINGE FILTERS

MUNKTELL and EDEROL offers you a wide range of diffe-rent syringe filters. In our programme you will find cellulo-se acetate-regenerated cellulose-PTFE – Polyethersulfoneand micro glass fibre syringe filters.

Each filter ist specially designed to maximize samplerecovering by housing design and proper choice ofmembrane.

Our 0.2 micron pore size syringe filters allow quicker steri-lization of up to 100 ml liquid volumes. Filters with largerpore sizes – from 0.45 up to 5 micron – are suitable forclarification of large volumes.

We offer you syringe filters and air venting units with4–15–25 and 50 mm diameter – sterile or non sterile – luerlock or luer slip connectors. The housing is made ofcyrolite or polypropylene.

Colour code

In order to identify the pore size we use the following colour for cellulose acetate syringe filters:

Blue – 0.2 micronYellow – 0.45 micronGreen – 0.8 micronRed – 1.2 micronBrown – 5.0 micron

PTFE and Regenerated cellulose syringe filters have CLEAR HOUSING. Prefilters of micro glass fibre paper haveWHITE HOUSING.

GENERAL INFORMATION MEMBRANES

MUNKTELL and EDEROL offers four types of membranefilters:

Cellulose – acetate, nitrate and regenerated cellulosePTFEPolyethersulfonePolyamide

This programme covers a very wide range of laboratoryfiltration applications. The pore size range is from 0.1 µm

up to 8 µm. We offer you membranes with a diameter from

13 mm up to 293 mm – sterile or non-sterile – white, black

or green – plain or gridded.

CELLULOSE ACETATE MEMBRANE FILTERS

These membranes combines very low adsorption charac-

teristics and thermal stability with high flow rates.

These membranes have a very low aqueous extractable,

< 0.1%, and are available in four pore sizes: 0.2 – 0.45 –

0.65 – 0.8 micron.

Typical applications are filtration of enzyme solutions to

minimize protein loss, diagnostic cytology, receptor bin-

ding studies, and general Sterilization and clarification of

aqueous and alcoholic solutions and oils.

MICRO FILTRATION

CELLULOSE NITRATE MEMBRANE FILTERS

Cellulose ester membrane filters are used in a wide variety of analy-

tical and laboratory procedures that require filtration. The cellulose

nitrate membrane filters is hydrophilic and has uniform pore sturctu-

re over a wide range of pore sizes and therefore is recommended for

sample pretreatment, particle testing and removal.

These membranes have a high non-specific adsorption

which makes them suitable for many blotting procedures

and for diagnostic kits. The adsorption decrease with

increasing pore size.

Sterile individually packed membrane filters are standard

for routine microbiological quality control. Filter identifi-

cation and lot number are printed on each individual

envelope. In our production each membrane and envelope

is checked.

All gridded membranes are made of cellulose nitrate, which assures excellent retention and colony growth. The

grid size is 3.1 x 3.1 mm and can be supplied in black, white and green grid. White membranes with black grid

and green membranes with dark green grid is used for colony counts. Gray/black membranes with white grid is

used for detection of yeasts and moulds. White membranes with green grid ist used for E.coli and coliforms.

In our programme you can also find gridded and sterile membranes with a pink-coloured hydrophobic edge for

sterility testing.

We also offer non-sterile gridded membranes in standard packs for particle counting and microscopy.

REGENERATED CELLULOSE MEMBRANE FILTERS

The regenerated cellulose membrane filter is chemically

resistant to allmost organic solvents and to aqueous solu-

tions in the pH range 3–12.

Regenerated cellulose membranes have low non-specific

adsorption which make them suitable for filtration of biolo-

gical solutions. They are also recommended for filtering

HPLC and mobile phases.

PTFE HYDROPHOBIC MEMBRANE FILTERS

The PTFE membrane filter is naturally and permanently

hydrophobic. It permit the passage of air and gases and it

does not become blocked with humidity. If it should be

used for filtration of aqueous solutions, it must be pre-

wetted with a solvent before water passage can occur.

PTFE membrane filters are ideal for venting applications,

phase separations, aerosol samplings and gas filtration.

NYLON MEMBRANE FILTERS

Nylon membrane are both hydrophilic and chemically resi-

stant to most bases which makes them very suitable as

particle-removing or sterilizing filters for alkaline solutions.

Good compatibility with many solvents and aqueous sam-

ples makes them an economical choice for clarification of

the mobile phases for HPLC.

The high adsorption and good mechanical strength makes

them useful for blotting techniques, such as transfer and

immobilization for nucleic acids.

For applications such as sterilizing filtration of tissue cul-

ture solutions they are not recommended. For such appli-

cations you should use cellulose acetate membranes.

GLASS FIBRE PREFILTERS

In general glass fibre filters have an open structure with a

large available surface area and filter depth. Compared

with a membrane they have a high dirt-loading capacity.

Because of the high dirtloading capacity they are often

used to protect membrane filters, giving an excellent

throughput and absolute retention.

We offer three different grades – with and without binder.

Filters without binder are recommended for analytical and

gravimetric analysis, and for the prefiltration of relative

clean solutions such as tissue culture media.

Pumpgard is a ready-to-connect filter unit, consisting of a

PTFE membrane filter sealed in a polypropylene housing.

Pumpgard stops aqueous overflow from a full flask to reach the

pump and prevents corrosions, expensive cleaning and break-

down of vacuum pumps.

PTFE CAPSULES

High air flow rates of the membrane and large filtration area allow effective sterile venting at low differential pres-

sure.

As PTFE is extremely hydrophobic we guarantee maximum reliability even when filtering moist air.

Each capsule is a ready to use, pre-tested, complete filter. The pleated PTFE membrane ensures maximal filtration

area.

We offer two different connectors and three different sizes

P Capsules with inlet and outlet hose nipples

P Capsules with inlet and oulet sanitary flanges

P Filtration areas 0.05 – 0.1 – 0.2 m2

For the filtration of those acids, bases and non-aqueous solvents for which our cellulose acetate capsules can not

be used PTFE capsules is an excellent choice.

SEED TESTING PAPERS

MUNKTELL Seed Testing Papers are widely used by seed

testing institutes and others for germination capacity testing

and for health tests e.g. Jacobsen (Copenhagen tank), on top

of paper and osmosis test.

MUNKTELL TOWELS have been especially developed for ger-

mination capacity testing of cereals. From an occupational

safety point of view, e.g. cleanliness and heavy weights to lift,

this method is widely preferred before the conventional

method of growing in sand. It also requires much less space.
