PTFE Syringe Filters, 0.22um, 30mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF18323

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18323

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 large 30mm diameter with 4.9cm² filtration area processes high-volume samples efficiently, and pre-sterilized packaging means contamination-free handling right out of the package. 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 removes bacteria and microorganisms from non-aqueous solutions
• 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 flow characteristics while maintaining sterility assurance levels

Key Construction Characteristics

• Polypropylene housing provides broad chemical compatibility with organic and inorganic solvent systems
• Large 30mm diameter with 4.9cm² filtration area enables rapid processing of high-volume sterile samples
• Holdup volume of 100µl minimizes sample loss while maintaining practical handling for routine applications
• 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 large 4.9cm² filtration area handles high-volume applications efficiently while maintaining bacterial retention, and you can process samples at temperatures up to 60°C without membrane degradation. The 17.4psi bubble point confirms consistent pore structure across production lots for reproducible results in your sterile filtration protocols.
