Whatman
GD/X 25mm Syringe Filter, PVDF Filteration Medium, 0.45um (1500 pcs) SKU: 6873-2504

Polyvinylidene Difluoride (PVDF) Syringe Filters, 0.45µm, 25mm - 6873-2504

Reducing background noise in analytical assays begins with proper clarification, and the Polyvinylidene Difluoride (PVDF) Whatman GD/X 25mm Syringe Filter, PVDF filtrationmedium, 0.45µm, 150/pk is engineered to remove interfering solids efficiently. 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. Encasing this critical media is a high-purity polypropylene housing that prevents sample bypass and ensures that every microliter is processed with high fidelity. Consequently, by reducing the risk of downstream contamination, these filters serve as a critical safeguard for the integrity of your experimental results.
