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

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

When maximizing protein recovery is critical, the Supor® Syringe Filters delivers an ultra-low binding surface that protects your valuable active ingredients. Driving this biological efficiency is an ultra-low protein binding surface that minimizes the loss of active ingredients during sterile filtration. 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.
