Acro Disc PSF Syringe Filters w/ Supor Membrane - GxF/0.2um, 25mm, 200/Pk SKU: AP-4799

Polyethersulfone (PES) Syringe Filters, 0.2µm, 25mm - AP-4799

Engineered for speed and recovery, the Supor® Syringe Filters processes buffers and tissue culture media significantly faster than standard PES devices. To ensure regulatory compliance, the Supor® membrane is validated for bacterial retention while offering faster processing than competitive PES. Designed to facilitate rapid processing, the housing features an optimized flow geometry that minimizes backpressure, allowing for easier manual filtration even with viscous samples. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.
