Pall
Acro Disc Syringe Filters w/ Supor Membrane, Sterile - 0.45um, 32mm, 50/Pk SKU: 4654

Polyethersulfone (PES) Syringe Filters, 0.45µm, 32mm - 4654

When maximizing protein recovery is critical, the Supor® Syringe Filters delivers an ultra-low binding surface that protects your valuable active ingredients. Central to this high-throughput capability is the Supor® PES membrane, optimized with an asymmetric pore structure to deliver superior flow rates. 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.
