        Property

        GVS 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 an alpha-cellulose content of nearly 100%. The ash content of less than 0.06% is not reduced by post-treatment.

        From Very Fast filtration to Very Slow filtration, GVS Qualitative Papers provide a wide range of solutions for all application needs.
