Whatman
GD/X 25mm Sterile Syringe Filter, PVDF Filteration Medium, 0.45um (50 pcs) SKU: 6900-2504

Polyvinylidene Difluoride (PVDF) Syringe Filters, 0.45µm, 25mm - 6900-2504

Reducing background noise in analytical assays begins with proper clarification, and the Polyvinylidene Difluoride (PVDF) Whatman GD/X 25mm Sterile Syringe Filter, PVDF filtrationmedium, 0.45µm 50/pk is engineered to remove interfering solids efficiently. Driving this clarification performance is a hydrophobic Polyvinylidene Difluoride (PVDF) membrane featuring a verified 0.45 pore structure that captures target particulates while minimizing holdup volume. To guarantee structural reliability, each unit undergoes strict quality control to ensure the housing and membrane seal withstand standard operating pressures without leakage. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.
