Pall
Acro Disc Syringe Filters w/ Ion Chromatography (IC) Supor Membrane - 0.45um, 25mm, 200/Pk SKU: AP-4585

Polyethersulfone (PES) Syringe Filters, 0.45µm, 25mm - AP-4585

Optimized for biological performance, the Supor® Syringe Filters combines high flow rates with the assurance of low preservative binding. 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. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.
