Acro Disc PSF Syringe Filters w/ PVDF Membrane - 0.45um, 25mm, 200/Pk SKU: AP-4408

Polyvinylidene Difluoride (PVDF) Syringe Filters, 0.45µm, 25mm - AP-4408

In high-throughput analytical laboratories, the Polyvinylidene Difluoride (PVDF) Syringe Filters series establishes a standard for effective particulate removal and sample clarification. Facilitating rapid sample turnover, the hydrophilic Polyvinylidene Difluoride (PVDF) membrane structure ensures the 0.45 rating remains consistent even under pressure. Complementing the membrane's purity, the housing's thermal bonding eliminates the need for adhesives, removing a common source of extractable contamination. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.
