Cytiva Whatman™ GD/X PTFE Syringe Filters

Description

Processes three to seven times more sample volume than filters without prefilter. Whatman™ GD/X PTFE Syringe Filters are specifically designed for filtration of viscous or otherwise hard-to-filter samples with high solids content.

Constructed of a polypropylene housing with a prefiltration stack of Whatman GMF 150 (graded density) and GF/F glass microfiber prefilters. This design prevents the buildup of back pressure typically caused by the blocking of an unprotected membrane.

• Syringe filter with integrated prefiltration
• Female Luer-Lok™ inlet; male slip Luer outlet
• Flow should enter from the inlet
• Autoclavable at 121°C (250°F) at 15psi for 20 min.
• Maximum temperature, 131°C (267°F) Filtration area: 13mm - 1.3cm²; 25mm - 4.6cm² Pressure limit: 13mm - 100psi; 25mm - 75psi
• All materials biosafe—pass USP Class VI requirements
• Prefiltration media: 100% Borosilicate glass fiber GMF 150 10μm: 1μm GF/F 0.7μm
• Disposable filtration devices provide labor saving efficiency while ensuring consistent filter performance
• High loading capacity for samples with high solids content
• Suitable for capillary electrophoresis, HPLC, and UV/VIS sample preparation

Nonsterile GD/X filters are available in two diameters: 13 mm and 25 mm, and three pore sizes: 0.2 μm, 0.45 μm, and 5 μm
