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.

For Use With (Application) Higher particulate loading capacity with faster flow rates

  • 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
