Filtrerpapir

Supplier: Ahlstrom

These quantitative ashless hardened filter papers are recommended for use where a high purity is required for quantitative analysis.

Supplier: Sartorius

These smooth filter papers are made of refined pulp and linters with more than 95% alpha-cellulose content. The ash content of these filter papers is between 0,1 and 0,15%.

Supplier: Sartorius

These papers satisfy the requirements for the determination of germination capability according to ISTA (International Seed Testing Association) and are ideal for ensuring optimal moisture content for the most diverse types of seeds and germination forms.

Supplier: Sartorius

This phase separating paper is impregnated with stabilised silicon, thus rendering it hydrophobic and it retains water, but allows solvents to flow through. The flow stops automatically when the entire solvent has passed through, this eliminates the need to use separating funnels.

Supplier: Sartorius

Chromatography papers are not only ideal for chromatography, but also for routine and repetitive separations, routine analysis of proteins in serum (e.g. human albumin) and several absorption applications like those common in the life sciences and diagnostics. They are made of cotton linters with more than 98% alpha-cellulose content and <0,04% ash content.

Supplier: Ahlstrom

These filter papers for suitable for special applications.

Supplier: Ahlstrom

These qualitative grades of filter paper are recommended for use in analytical methods which determine or identify particulate constituents of a mixture irrespective of the amount present. Qualitative filter papers are often used in routine separation work that still requires high purity and consistent performance. These filter papers cover a wide range of laboratory applications, as liquids clarification, qualitative analytical separations for precipitates and buffers filtration, and are also used for soil analysis and in food and beverage testing. Wet-strengthened grades contain a reinforcement agent that increases their resistance to rupture when wet, such as in vacuum filtration, and their resistance when filtering acidic solutions.

Frøkontrolpapir anvendes hyppigt af frøkontrolinstanser og andre med henblik på spiringsbestemmelse af såsæd og til sundhedstest f.eks Jacobsen (Copenhagen tank), udover papir- og osmosetest.

Supplier: Ahlstrom

Følgende filrerpapir opfylder specifikke tekniske krav svarende til de krav, der fremgår ovenfor. Præget filtrerpapir har et større overfladeareal og har derfor tilsvarende kortere filtreringsperioder. De har en meget homogen struktur med fine porer.

Supplier: Ahlstrom

Ahlstrom-Munksjö manufactures a series of extremely high purity, acid washed filter papers designed for use in analytical and gravimetric analysis. The quantitative grades are manufactured from top quality cotton linters using ultra-pure, deionised water and are further treated with dilute acid to remove any remaining organic and inorganic impurities. All quantitative grades are manufactured in a strictly controlled environment that ensures high uniformity and high purity from filter to filter.

Filter paper, quantitative, 28 mm

Supplier: MACHEREY-NAGEL

MN 619 eh is slightly more dense than MN 619 with high particle retention and slow flow rate.

Supplier: MACHEREY-NAGEL

MN 618 is a thick filter paper with medium flow rates and finer retention. It's higher loading capacity than thinner papers makes it especially useful for the filtration of large quantities of liquids.
