Broad range of filter papers. You can choose from quantitative, qualitative, qualitative-technical filter papers, blotting and chromatography filter papers and many other paper grades for special applications. Our filter papers are depth filters and typical applications are particle retention in gases or aqueous solutions.
This filter grade is made of cellulose and diatomaceous earth and offer a much better separating capability than pure cellulose papers at the same rate of filtration. This grade quickly retains the finest particles at high flow rates.
Labsorb is a surface protection paper. It is a highly absorptive grade of paper coated on one side with polyethylene.
This highly pure paper grade are not only ideal for blotting and chromatography, but also for a wide range of absorption applications like those common in the life sciences and diagnostics.
These filter papers are used for quantitative and gravimetric analyses as well as for pressure or vacuum filtration. They are made out of 100 % cotton linters with an α-cellulose content of > 98 % and are acid-washed to make the papers ashless and achieve high purity.
These qualitative filter papers are essentially used for analytical purposes and routine analyses, whenever no gravimetric analyses are required. They are wet-strengthened and can be used for pressure and vacuum filtration. They are made of refined pulp and linters with an > 95% α-cellulose content, are very pure with an ash content < 0.1%.
