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

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18323

Featuring hydrophobic PTFE membrane technology with 0.22µm pore size in pre-sterilized packaging for reliable sterile filtration and bacteria removal from aggressive solvents. Large 30mm diameter filters deliver exceptional 29.5ml flow rates while maintaining complete microbial retention for high-volume aseptic applications. Polypropylene housing construction ensures robust performance at pressures up to 87psi across demanding sterile protocols.

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
• Superior 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

SF18323 filters maximize your sterile filtration efficiency with an impressive 29.5ml flow rate, significantly reducing processing time for large-volume samples. Pre-sterilized packaging ensures immediate use while your samples maintain complete sterility at operating temperatures up to 60°C. Bubble point verification at 17.4psi using absolute ethyl alcohol confirms membrane integrity for your critical sterile filtration requirements.
