Filter Papers

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.

Diatomaceous Earth Filter Paper/ Grade 470

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.

Quantitative Papers/ Grade 391
Item no.: FT-2-104-580580

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.

Qualitative Papers/ Grade 1288
Qualitative Papers/ Grade 1288
Item no.: FT-2-206-400800

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%.
