Low Ash/Medium-Slow Qualitative Filter Papers (GVS) are ideal for monitoring specific contaminants in the atmosphere and soil testing. For the filtration of fine precipitates.

Qualitative low ash hardened filter paper is used in qualitative analytical techniques to determine and identify materials. Qualitative filter papers are made of refined pulp and pure cotton linters with alpha-cellulose content of nearly 100%. The ash content of less than 0.06% is not reduced by post-treatment.

General Applications: Qualitative analysis, general filtration, soil analysis, air monitorin
