Polytetrafluoroethylene (PTFE) Syringe Filters - SF18241

When you need to remove bacteria from aggressive solvents and corrosive reagents, you need both sterile-grade filtration and broad chemical resistance. These 0.22µm PTFE filters handle everything from strong acids to halogenated organics while removing bacteria from non-aqueous solutions. The 17mm diameter with 2.27cm² filtration area balances throughput with low sample retention (20µL holdup volume), and pre-sterilized packaging means contamination-free handling. Polypropylene housing withstands pressures up to 87psi across demanding chemical applications.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophobic membrane design provides sterile filtration of organic solvents, acids, and bases without degradation
• Sterile-grade 0.22µm pore size ensures complete removal of bacteria and microorganisms for aseptic processing
• Pre-sterilized by gamma irradiation eliminates preparation steps for critical contamination-free applications
• Broad chemical resistance from strong carbon-fluorine bonds withstands aggressive solvents and reagents
• Membrane thickness of 80-140µm optimizes retention efficiency while maintaining adequate flow characteristics

Key Construction Characteristics

• Polypropylene housing provides broad chemical compatibility with organic and inorganic solvents
• 17mm diameter with 2.27cm² filtration area for medium-volume sample processing
• Low holdup volume of 20µl minimizes sample loss while maintaining practical handling characteristics
• Luer-Lok/Luer Slip dual connection system ensures secure attachment to various syringe sizes

Pre-sterilized packaging means you can start filtering immediately without autoclaving preparation, saving time when processing multiple samples. The 20µL holdup volume maximizes sample recovery - important for expensive reagents or limited-volume specimens. Process samples at temperatures up to 60°C without membrane degradation, and the 17.4psi bubble point confirms consistent pore structure for reproducible bacterial retention in your sterile filtration protocols.
