PTFE Syringe Filters, 0.22um, 17mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF18241

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18241

Featuring hydrophobic PTFE membrane technology with 0.22µm pore size in pre-sterilized packaging for reliable sterile filtration and bacteria removal from aggressive solvent systems. Intermediate 17mm diameter filters balance efficient flow rates with minimal holdup volume for versatile sterile filtration applications. Polypropylene housing construction ensures chemical compatibility at pressures up to 87psi across demanding aseptic 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 retention efficiency while maintaining adequate flow characteristics

Key Construction Characteristics

• Polypropylene housing provides broad chemical compatibility with organic and inorganic solvents
• Intermediate 17mm diameter with 1.65cm² filtration area, ideal for medium-volume sterile 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

SF18241 filters optimize your sterile filtration workflow with a 10ml flow rate that balances thorough bacterial removal with practical throughput. 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.
