Whatman Grade GF/F Glass Fiber Filters

This ultrafine paper is fast flowing and retains particles down to 0.7 µm. Highest retentive GF Grade. Rate of flow is 6.0 ml/sec. Loading capacity is extremely high. Absorption of water is 400 ml/m2. Strength when wet is high. For collecting very fine precipitated proteins. For highly effective clarification of biochemical/biological and other fluids difficult to clarify (e.g., filtration of dilute aqueous solutions containing strongly oxidizing, acidic or alkaline constituents prior to Raman laser spectroscopy).
