MicroAnalytix offers a wide choice of quantitative Filter Papers.
Quantitative Filter Papers/ Hardened Filter Papers are used for quantitative and gravimetric analyses where the precipitate is to be recovered, as well as for pressure or vacuum filtration. Hardened low ash grade papers are acid-treated to remove trace metals, produce high wet strength, and chemical resistance. The tough, smooth surface of these filters makes it easy to recover precipitates, rendering them particularly suitable for Büchner filtration. Hardened ashless grade filters combine acid-hardening with extremely low ash content, making them suitable for a wide range of critical filtration procedures.
