Whatman™ GD/X Sterile Glass Micro Fiber (GMF) Syringe Filters

Constructed of a polypropylene housing with a prefiltration stack of Whatman GMF 150 (graded density) and GF/F glass microfiber prefilters. This design prevents the buildup of back pressure typically caused by the blocking of an unprotected membrane.
