Glass Microfibre Filter Paper - 453

Filtech Grade 453 is a high performance grade, designed to retain extremely fine particles down to 0.7um. Grade 453 has retention comparable to a membrane filter while providing higher flow and loading capacity. It is recommended for filtering fine precipitated proteins.

In the filtration of nucleic acids and difficult biochemical solutions, Grade 453 is used in combination with Filtech Grade 423 as a highly efficient protective and retentive pre-filter to extend the loading capacity of membrane filters.

Grade 453 is recommended for use in TCLP procedure as described in test methods for evaluating solid wastes, EPA method 1311.
