Acro Disc Syringe Filters w/ PVDF Membrane - 0.2um, 13mm, Minispike Outlet, 1000/Pk SKU: 4544

Polyvinylidene Difluoride (PVDF) Syringe Filters, 0.2µm, 13mm - 4544

For critical applications requiring absolute sterility assurance, the Polyvinylidene Difluoride (PVDF) Syringe Filters series provides a verified barrier against bacterial contamination. Driving this efficiency is the integration of a hydrophilic Polyvinylidene Difluoride (PVDF) membrane, ensuring high recovery of sensitive samples while maintaining a sterile effluent. Encasing this critical media is a high-purity polypropylene housing that prevents sample bypass and ensures that every microliter is processed with high fidelity. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.
