Glass Microfiber Filters - Grade 121


1.0 µm, 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.
