詳細

詳細

Non-sterile syringe filters with a polytetrafluoroethylene (PTFE) membrane and polypropylene prefilter. 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. 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.

特徴および利点

• Incorporates a two-layer polypropylene prefilter stack rather than a multi-layer glass fiber stack to minimize levels of ion extractables
• Extremely low protein binding syringe filter
• High loading volume for filtration of challenging samples

適合性

Suitable for filtering trace metal analysis samples and for particulate laden sample preparation.
