Ahlstrom-Munksjö’s 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 covers 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.

Grade 470 papers are made of cellulose and diatomaceous earth and offer a much better separating capability than pure cellulose papers at the same rate of filtration.

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: Ahlstrom

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

These papers are used to determine the presence of trace elements and nutrients in soil samples to optimise plant growth.

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.

These filter papers are suitable for use in wine laboratories.

Supplier: Sartorius

Disse filterpapirer er fremstillet af raffineret papir og linter med et indhold på over 98 % alfa-cellulose. De er garanteret fri for restsyrer og de har et ekstremt lavt procentvis askeindhold. Dermed er disse filtre stort set askefrie. Alle askefrie Sartorius filterpapirer karakteriseres ved en høj vådstyrke og høj renhedsgrad, hvorfor de er specielt velegnede til kvantitativ analyse, Büchner-tragte, tryk-eller vakuumfiltrering.
