Pall
Acro Disc Syringe Filters w/ wwPTFE Membrane - 0.45um, 25mm, 50/pk SKU: 4914TC

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

The Acrodisc® One with wwPTFE (Water-Wettable PTFE) membrane dissolves the traditional distinction between aqueous and organic filtration workflows. Central to this universality is the wwPTFE membrane, which remains chemically compatible with aggressive solvents while being fully water-wettable. 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.
