Description:
Cytiva Whatman 6995-2504 GD/XP 25mm x 0.45µm PES Syringe Filters with PP Prefilters, 1500/pack. Whatman GD/XP 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. GD/XP Syringe Filters combine a Polyethersulfone (PES) membrane filter with a polypropylene housing, high-efficiency Whatman GMF 150 and GF/F pre-filter media.
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. 1500/pack.
