GD/X 25mm Sterile Syringe Filter, PVDF Filteration Medium, 0.2um (50 pcs)
Whatman SKU: 6900-2502

Whatman GD/X PVDF Syringe Filters, 0.2 µm, 25 mm, 50/Pk - 6900-2502

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. Hydrophilic PVDF minimizes protein binding for high HPLC sample recovery while holding up to alcohols and mild hydrocarbon solvents and wets aqueous and HPLC samples on contact. Polypropylene construction maintains housing integrity through the filtration run and resists aqueous acids, bases, and alcohols. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.
