Cytiva Whatman™ Binder-Free Glass Microfiber Filters GF/F Circles
Served as the basis filter for EPA standard for the toxicity characteristic leaching procedure. Whatman™ Binder-Free Glass Microfiber Filters GF/F Circles offers an extremely high loading capacity and flow rate.

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.
