Whatman Multigrade 150 Glass Fiber Filters

Description

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.
