Acro Disc PSF Syringe Filters w/ PVDF Membrane - GxF/0.45um, 25mm, 1000/Pk SKU: AP-4308

Polyvinylidene Difluoride (PVDF) Syringe Filters, 0.45µm, 25mm - AP-4308

Designed to protect sensitive chromatography columns from clogging, the Polyvinylidene Difluoride (PVDF) Syringe Filters delivers exceptional retention of particulates without compromising flow rates. At the core of the device is a uniform Polyvinylidene Difluoride (PVDF) matrix, delivering high dirt-loading capacity and reliable exclusion of interfering particles. Complementing the membrane's purity, the housing's thermal bonding eliminates the need for adhesives, removing a common source of extractable contamination. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.
