PTFE Syringe Filters, 0.1um, 33mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF18089

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18089

Featuring hydrophobic PTFE membrane technology with ultra-fine 0.1µm pore size in pre-sterilized packaging for exceptional submicron filtration of aggressive solvents. High-capacity 33mm diameter filters deliver 12ml flow rates while removing viruses, fine particles, and small molecules from critical samples. Polypropylene housing construction ensures chemical compatibility at pressures up to 87psi across demanding sterile applications.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophobic membrane design effectively filters organic solvents, acids, and bases without chemical degradation
• Ultra-fine 0.1µm pore size removes submicron particles, viruses, and small molecular contaminants from samples
• Pre-sterilized by gamma irradiation ensures contamination-free filtration for critical aseptic applications
• Superior chemical resistance from strong carbon-fluorine bonds maintains integrity in caustic solvent systems
• Membrane thickness of 80-140µm optimizes retention efficiency while maintaining adequate flow characteristics

Key Construction Characteristics

• Polypropylene housing provides excellent chemical compatibility with organic and inorganic solvents
• Large 33mm diameter with 4.9cm² filtration area, ideal for high-volume sterile analytical applications
• Holdup volume of 100µl balances sample recovery with practical handling for routine processing
• Luer-Lok/Luer Slip dual connection system accommodates various syringe sizes and automated systems

SF18089 filters optimize your high-volume sterile submicron filtration with a 12ml flow rate that balances thorough particle 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 26.11psi using absolute ethyl alcohol confirms exceptional membrane integrity for your critical sterile submicron filtration requirements.
