GVS Low Ash/Medium Qualitative Filter Papers are ideal for a wide range of laboratory applications: separation of precipitates (lead sulfate, calcium oxalate, calcium carbonate), soil analysis, seed testing, separation of solid foodstuff or extracting liquid, atmospheric dust collection, and gas detection.

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, clarifying liquids, soil analysis and seed testing, food analysis, air monitoring.
