Acro Disc PSF Syringe Filters w/ PTFE Membrane - GxF/0.45um, 25mm, 1000/Pk SKU: AP-4302

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.45µm, 25mm - AP-4302

For researchers requiring consistent baselines in HPLC and dissolution testing, the Polytetrafluoroethylene (PTFE) Syringe Filters offers a robust solution for extending instrument life. Facilitating rapid sample turnover, the hydrophobic Polytetrafluoroethylene (PTFE) membrane structure ensures the 0.45 rating remains consistent even under pressure. Complementing the membrane's purity, the housing's thermal bonding eliminates the need for adhesives, removing a common source of extractable contamination. Meeting the needs of regulated environments, this series supports compliance with stringent purity protocols across pharmaceutical and environmental applications.
