Acro Disc Syringe Filters w/ wwPTFE Membrane - 0.45um, 25mm, 1000/Pk SKU: 4932

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.45µm, 25mm - 4932

Simplify your laboratory inventory with the Polytetrafluoroethylene (PTFE) Syringe Filters, a truly universal filter capable of handling aggressive solvents and water-based samples alike. Driving this analytical precision is an HPLC-certified membrane that ensures low UV-absorbing extractables for noise-free baselines. 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.
