PTFE Hydrophilic Syringe Filters, 0.22 um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk SKU: SF18001

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18001

Bacterial contamination and sterile filtration challenges in critical laboratory applications require immediate intervention without compromising sample integrity. Pre-wetting protocols and membrane compatibility issues frequently delay time-sensitive analytical workflows, creating bottlenecks in research productivity. Advanced hydrophilic PTFE membrane technology at 0.22μm pore size eliminates these obstacles through surface-modified fluoropolymer chemistry that ensures immediate aqueous wetting while delivering absolute bacterial retention. Technical specifications include 43.51psi bubble point validation, 100μL holdup volume optimization, and autoclavable construction supporting both 121°C steam sterilization and 25kGy gamma protocols.
