Polyvinylidene Difluoride (PVDF) Syringe Filters, 0.2µm, 25mm - AP-4794

Eliminate the risk of microbial contamination in your upstream workflows with the Polyvinylidene Difluoride (PVDF) Syringe Filters, optimized for sterile filtration protocols. Central to this performance is a hydrophilic Polyvinylidene Difluoride (PVDF) membrane with a precise 0.2 pore structure that ensures the complete removal of bacteria and fine particulates. Encasing this critical media is a high-purity polypropylene housing that prevents sample bypass and ensures that every microliter is processed with high fidelity. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.
