Pall
Acro Disc Syringe Filters w/ Ion Chromatography (IC) Supor Membrane - 0.45um, 13mm, 300/Pk SKU: 4485

Polyethersulfone (PES) Syringe Filters, 0.45µm, 13mm - 4485

Engineered for speed and recovery, the Supor® Syringe Filters processes buffers and tissue culture media significantly faster than standard PES devices. At the core of the device is the specialized polyethersulfone matrix, which resists clogging to filter greater volumes of biological fluids. 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.
