Whatman No. GF/F is a high efficiency filter that will retain fine particles down to 0.7¬µm. Unlike membrane filters with a comparable retention value, it has a very rapid flow rate and an extremely high loading capacity. Suitable for critical applications including enumeration of Salmonella and Pseudomonas Aeroginosa, clarification of protein solutions and filtering samples and solvents prior to HPLC. Because of the tight specification of 0.6¬µm-0.8¬µm particle retention and pure borosilicate glass structure, GF/F is the material upon which the EPA Method TCLP 1311 for Toxicity Characteristic Leaching Procedure was developed. It remains today the filter of choice. Recommended for DNA binding and purification. Very effective in filtering finely precipitated proteins, GF/F can be used in conjunction with GF/D as a prefilter for the successful clarification of extremely "difficult" biochemical solutions and fluids, and nucleic acids.
