Supplier: Ahlstrom

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.

Les filtres à microquartz sont utiles pour tester les gaz de cheminée chauds, car les fibres de quartz peuvent résister à des températures allant jusqu'à 900 °C. De plus, le microquartz est utilisé lorsqu'un média de la plus haute pureté est requis. Avec d'excellentes propriétés de filtration et des traces minimes de métaux et de minéraux, les fibres de quartz sont dimensionnellement stables et peuvent être utilisées pour l'analyse des gaz acides à l'exception de l'acide fluorhydrique.

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 BioSample cards are designed for microvolume sampling, transport and ambient storage of biological samples. These cards are made of white and pure absorbent fibers and contain no wet-strength additives or chemicals. This feature ensures reproducible collection and minimise possible interferences for reliable analysis of targeted analytes like small molecules, proteins, nucleic acids or vitamins.

Double-layered LabSorb papers protect benches and working areas from spilled chemicals, corrosive materials, as well as toxic, infectious or radioactive substances. Spills are quickly absorbed into the surface layer of cellulose material and prevented from penetrating to the surface of the work bench by a thin coating of polyethylene that serves as a carrier for the absorbent layer.
