Filtry strzykawkowe z prefiltrem GD/X, sterylne
Sterylne filtry strzykawkowe GD/X przeznaczone są do filtracji lepkich, trudnych do sączenia próbek o wysokiej zawartości substancji stałych.
Whatman™ GD/X sterile syringe filter is designed to support filtration of viscous, hard-to-filter samples with high solids content.

• Reduces need for multiple syringe filters by processing three to seven times more sample volume than syringe filters without prefilters
• Female luer lock for leak-free connections
• High-efficiency Whatman™ GMF 150 and GF/F pre-filter media
• Eliminates or greatly reduces the need to carry out separate prefiltration step for difficult-to-filter samples

Sterile syringe filter for difficult-to-filter samples
We also offer nonsterile Whatman™ GD/X syringe filters.

GD/X sterile syringe filter is suitable for preparing viscous, dense, or otherwise hard-to-filter samples prior to a variety of analytical methods.

Sterile GD/X syringe filters combine a polypropylene housing, Whatman™ GMF 150 and GF/F pre-filter media, and one of the following membrane materials:

• Polyethersulfone (PES)
• Polyvinylidene difluoride (PVDF)
• Cellulose acetate
• Glass microfiber
