Grade F binderless borosilicate glass microfiber filters have a fine porosity, medium flow rate, a 0.7μm size particle retention, and a 2.8μm mean pore size. Although primarily used with Grade D filters to filter diluted aqueous solutions containing strong oxidizing, acidic, or alkaline components prior to laser spectroscopy, these Grade F filters may also be used for TCLP analysis and collecting extremely fine precipitated proteins; including immunoglobulins.
