Acro Disc PSF Syringe Filters w/ PTFE Membrane - 0.45um, 25mm, 200/Pk SKU: AP-4219

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.45µm, 25mm - AP-4219

In high-throughput analytical laboratories, the Polytetrafluoroethylene (PTFE) Syringe Filters series establishes a standard for effective particulate removal and sample clarification. Facilitating rapid sample turnover, the hydrophobic Polytetrafluoroethylene (PTFE) membrane structure ensures the 0.45 rating remains consistent even under pressure. 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.
