Processes three to seven times more sample volume than filters without prefilter. Whatman™ GD/X Nylon Syringe Filters are specifically designed for filtration of viscous or otherwise hard-to-filter samples with high solids content.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.
