Filtry strzykawkowe z prefiltrem GD/X, niesterylne
Filtry strzykawkowe GD/X przeznaczone są do filtracji próbek lepkich lub trudnych do sączenia o wysokiej zawartości substancji stałych.
Whatman™ GD/X syringe filters are specifically designed for filtration of viscous or otherwise hard-to-filter samples with high solids content.

• Glass fiber prefiltration stack for filtering larger sample volumes with less back pressure build-up
• High loading capacity for samples with high solids content
• Processes three to seven times more sample volume than filters without prefilter
• 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

Sterile GD/X options are also available.

Syringe filter with integrated prefiltration
Constructed of a polypropylene housing with a prefiltration stack of Whatman™ GMF 150 (graded density) and GF/F glass microfiber prefilters, GD/X syringes enable exceptional loading capacity with high flow rates for difficult-to-filter samples. This design prevents the buildup of back pressure typically caused by the blocking of an unprotected membrane.

GD/X syringes are suitable for capillary electrophoresis, HPLC, and UV/VIS sample preparation when dealing with viscous or otherwise difficult-to-filter samples with high solids content.

GD/X membrane options for chemical compatibility
Whatman™ GD/X syringe filters are manufactured with a wide range of membrane materials to support your specific application. Options include:

• Nylon syringe filters
• High-charge nylon syringe filters
• PES syringe filters
• PVDF syringe filters
• PTFE syringe filters
• Polypropylene syringe filters
• Cellulose acetate syringe filters
• Glass fiber syringe filters
• Regenerated cellulose syringe filters
