Cytiva, 1841-090, Whatman™ Multigrade 150 Glass Fiber Filters

Whatman Glass Microfiber Prefilter, 1 µm particle retention rating, 90 mm circles (20 pcs) Cytiva's Whatman GMF 150 prefilters are multilayer graded density filters for rapid and efficient filtration of samples with high solids content. • Compared to an unprotected membrane, greater sample volume can be filtered • Higher particulate loading capacity and faster flow rates than uniform prefilters • Excellent particle retention (both large and small particles) • 100% borosilicate glass, binder-free • Extends life of final filter membrane Multilayer filter design When a sample is applied, the multigrade glass filter traps larger particles in its pores or on the surface of the coarse layer, medium-sized particles in the interface meshing, and smaller particles in the interstices of the fine layer. The multilayer design provides comprehensive particle retention. Cytiva's glass microfiber prefilters Looking for a filter paper, membrane filter, or syringe filter?
