Cytiva Whatman™ Glass Microfiber Prefilter, 1μm Particle Retention Rating
Multilayer graded density filters for rapid and efficient filtration of samples with high solids content. Whatman™ Glass Microfiber Prefilters are designed with a coarse glass filter top layer (10μm) meshed with a finer layer. The multigrade glass filter traps larger particles in its pores of the coarse layer, medium-sized particles in the interface meshing, and smaller particles in the interstices of the fine layer.

Description
- Multilayer graded density filters for rapid and efficient filtration of samples with high solids content
- Whatman™ Glass Microfiber Prefilters are designed with a coarse glass filter top layer (10μm) meshed with a finer layer
- The multigrade glass filter traps larger particles in its pores of the coarse layer, medium-sized particles in the interface meshing, and smaller particles in the interstices of the fine layer
- Can filter nearly twice as much sample volume as that of a single-density prefilter Compared to an unprotected membrane, three to seven times 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
