Glass Microfiber Filter Paper - 1210-0700 - Grade 121, 7cm 11cm collecting hydroxides after precipitation by

collecting hydroxides after precipitation by strong alkalis and in the analysis of metals in acid and alkali solutions

Grade 151 has retention comparable to membrane filter while providing high flow and loading capacity

Ahlstrom-Munksjö 121

Grade 55 is also used in air and foodstuffs analysis and for chloride and phosphorous in cement

This eliminates the need to acid-wash the filters in your lab

Glass Microfiber Filter Paper - 1210-0700 - Grade 121, 7cm 11cm collecting hydroxides after precipitation byAhlstrom Munksj 121 1. 0 m, Medium Speed This very thick grade offers finer particle than Grade 111 with high wet strength and loading capacity. Grade 121 is recommended for the clarification of liquid suspensions loaded with fine particulates. Grade 121 is also used in membrane pre filtration and is also found in quantification of solids, and LSC (Liquid Scintillation Counting) techniques that require high loading capacity.
