Multigrade GMF 150 Glass Microfiber Prefilter, circle, 1 µm particle retention rating, 47 mm Whatman GMF 150 circles is a multilayer glass microfiber filter which, used as a prefilter, nearly doubles the volume of sample filtered compared to a single density prefilter. Higher particulate loading capacity. Faster flow rate. Extended life of filter. Whatman GMF 150 is a multilayer glass microfiber filter with a coarse top layer (10 µm) meshed with a finer layer of 1.0 µm or 2.0 µm. Manufactured from 100% borosilicate glass microfiber, the filter is binder free. It is an excellent choice of prefilter for higher particulate loading capacity with faster flow rates. The GMF 150 represents a new dimension in separation science leading to faster and more costeffective filtration. In application, the GMF 150* traps larger particles in the pores or on the surface of the coarse layer while the medium sized particles are caught in the interface meshing. The smaller particles are netted in the interstices of the fine layer. Multiple porosities, greater filtration efficiency Whatman Multigrade GMF 150, used as a prefilter, nearly doubles the volume of sample filtered compared to a single density prefilter. Compared to an unprotected membrane, the volume of sample filtered is three to seven times greater. Conventional prefilters cannot perform in the same way as the Multigrade GMF 150 simply because prefilters of a uniform density do not have the loading capacity of the multiporosity filter technology advanced by Whatman. For highly particulate loaded samples, the performance of GMF 150 filters is recommended.
