Pall
Acro Disc Syringe Filters w/ wwPTFE Membrane - 0.2um, 25mm, 200/Pk SKU: 4927

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.2µm, 25mm - 4927

The Acrodisc® One with wwPTFE (Water-Wettable PTFE) membrane dissolves the traditional distinction between aqueous and organic filtration workflows. At the core of the filter is a stabilized PTFE matrix that provides universal chemical resistance without the hydrophobicity of standard Teflon. To guarantee structural reliability, each unit undergoes strict quality control to ensure the housing and membrane seal withstand standard operating pressures without leakage. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.
