GE Whatman GD/X Syringe Filters 25 mm contain a unique prefiltration stack of GE Whatman Multigrade GMF 150 (10:1 µm) and Grade GF/F (0.7 µm) prefilters. This combination of coarse glass microfibers, over fine glass microfibers, over a third prefiltration layer ensures that particles down to 0.7 µm are retained before the sample reaches the final membrane filter. This translates to filtering the most difficult samples with less hand force than ever before. In addition when compared to that of an unprotected membrane, the volume sampled is three to seven times greater.
GD/X Syringe Filters are available in a wide variety of filter media choices with a polypropylene housing. Filters feature standard female Luer-Lock inlet and male slip luer outlet. Select 25 mm membranes are available gamma sterilized and individually blister packed for aseptic filtration.
Unique prefilter media promotes easy filtration with high throughput
