Low-Ash Hardened Quantitative Filter Papers
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.

BioSample cards
Supplier: Ahlstrom
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.

High purity hardened qualitative filter paper
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. High Purity hardened filter papers grades 1288 to 1291 are also produced from cellulose with an alpha content of nearly 100% resulting in an ash content of <0,1%.

Micro-quartz fibre filters
Supplier: Ahlstrom
Micro-quartz filters are useful for testing hot "stack" gases as the quartz fibers can withstand temperatures up to 900 °C. In addition, micro-quartz is used when the highest purity media is required. With excellent filtration properties and minimal traces of metals and minerals, quartz fibers are dimensionally stable and can be used in the analysis of acidic gases with the exception of hydrofluoric acid.

Industrial Filter Papers
Supplier: Ahlstrom
The following filter papers fulfill specific technical requirements corresponding to the requirements mentioned overleaf. Embossed filter papers have a larger surface area and, therefore, correspondingly shorter filtration times. They show a very homogenous and fine pore structure.

Surface protection papers, LabSorb
Supplier: Ahlstrom
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.
