Glass Microfiber Filters - Grade 151


0.7 µm, Slow Speed

This high performance grade is designed to retain extremely fine particles down to 0.7 µm. Grade 151 has retention comparable to membrane filter while providing high flow and loading capacity. Grade 151 is recommended for filtering fine precipitated proteins. In the filtration of nucleic acids and difficult biochemical solutions, Grade 151 is used in combination with Grade 141 as a highly efficient protective and retentive pre-filter to extend the loading capacity of membrane filters. Grade 151 is recommended for use in TCLP procedure as described in test methods for evaluating solid wastes, EPA method 1311.
