Whatman
GD/X 25mm Syringe Filter, PVDF Filteration Medium, 0.45um (150 pcs) SKU: 6872-2504

Polyvinylidene Difluoride (PVDF) Syringe Filters, 0.45µm, 25mm - 6872-2504

Designed to protect sensitive chromatography columns from clogging, the Polyvinylidene Difluoride (PVDF) Whatman GD/X 25mm Syringe Filter, PVDF filtrationmedium, 0.45µm, 150/pk delivers exceptional retention of particulates without compromising flow rates. To ensure analytical precision, the unit is constructed with a high-grade Polyvinylidene Difluoride (PVDF) membrane providing a consistent 0.45 cutoff that passes only your target analyte. To guarantee structural reliability, each unit undergoes strict quality control to ensure the housing and membrane seal withstand standard operating pressures without leakage. Consequently, by reducing the risk of downstream contamination, these filters serve as a critical safeguard for the integrity of your experimental results.
