Whatman
GD/XP Syringe Filter, PVDF Filteration Medium, 0.45um (150 pcs) SKU: 6972-2504

Polyvinylidene Difluoride (PVDF) Syringe Filters, 0.45µm, 25mm - 6972-2504

Reducing background noise in analytical assays begins with proper clarification, and the Polyvinylidene Difluoride (PVDF) Whatman GD/XP Syringe Filter, PVDF filtrationmedium, 0.45µm, 150/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. Designed to facilitate rapid processing, the housing features an optimized flow geometry that minimizes backpressure, allowing for easier manual filtration even with viscous samples. Consequently, by reducing the risk of downstream contamination, these filters serve as a critical safeguard for the integrity of your experimental results.
