Pall
Acro Disc Syringe Filters w/ wwPTFE Membrane - 0.45um, 25mm, 200/Pk SKU: 4914

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.45µm, 25mm - 4914

Designed to eliminate the risk of selecting the wrong filter, the wwPTFE membrane offers broad chemical compatibility without the need for pre-wetting. At the core of the filter is a stabilized PTFE matrix that provides universal chemical resistance without the hydrophobicity of standard Teflon. 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.
