Whatman GD/X Syringe Filters are high-viscosity filters that incorporate a prefilter to enable filtration of viscous, dense or otherwise hard-to-filter material with high solids content as in environmental and food analysis samples. Discontinuation notice : effective immediately, this product is being discontinued with no options for last time purchases. This action is the result of a supply discontinuation of critical raw material. Please click here for additional information and recommendation on alternative products.

Watch our video to see the advantages of a Whatman GD/X filter vs. a standard syringe filter
Non sterile Whatman GD/X Syringe Filters combine a polypropylene housing, high-efficiency Whatman GMF 150 and GF/F pre-filter media, and one of the following membrane materials:
Polyethersulfone (PES) for serum, plasma and tissue culture
Polyvinylidene difluoride (PVDF) for HPLC
Cellulose acetate for biological solutions
Borosilicate glass microfiber
High viscosity filter enables filtration of “difficult-to-filter” samples
The prefilter contains a high-efficiency borosilicate glass filtration stack that will retain fine particles down to 0.7 μm, allowing difficult sample filtration with less hand force. It reduces the need for multiple syringe filters by processing three to seven times more sample volume than syringe filters without prefilters. The filters can be autoclaved.
