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

Polyvinylidene Difluoride (PVDF) Syringe Filters, 0.2µm, 25mm - 6900-2502

When sample purity is non-negotiable, the Polyvinylidene Difluoride (PVDF) Whatman GD/X 25mm Sterile Syringe Filter, PVDF filtrationmedium, 0.2µm 50/pk serves as a reliable safeguard, effectively removing microorganisms from aqueous solutions. Central to this performance is a hydrophobic Polyvinylidene Difluoride (PVDF) membrane with a precise 0.2 pore structure that ensures the complete removal of bacteria and fine particulates. Encasing this critical media is a high-purity polypropylene housing that prevents sample bypass and ensures that every microliter is processed with high fidelity. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.
