Pura Disc 13mm PVDF Syringe Filters, 0.45um, 50 Pk SKU: 6791-1304

Polyvinylidene Difluoride (PVDF) Syringe Filters, 0.45µm, 13mm - 6791-1304

For researchers requiring consistent baselines in HPLC and dissolution testing, the Polyvinylidene Difluoride (PVDF) Whatman Puradisc, 13mm, Polyvinylidene Difluoride Syringe Filter, sterile, 0.45µm 50/pk offers a robust solution for extending instrument life. 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. 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.
