This high-efficiency filter 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.
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.
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.
