PTFE Syringe Filters, 0.45um, 17mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF18242

Polytetrafluoroethylene (PTFE) Syringe Filters - SF18242

Featuring hydrophobic PTFE membrane technology with 0.45µm pore size in pre-sterilized packaging for reliable clarification and particle removal from aggressive solvent systems. Intermediate 17mm diameter filters balance efficient 20ml flow rates with minimal holdup volume for versatile sterile filtration applications. Polypropylene housing construction ensures chemical compatibility at pressures up to 87psi across diverse aseptic protocols.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophobic membrane design effectively clarifies organic solvents, acids, and bases without chemical interaction
• Precision 0.45µm pore size removes particles, suspended solids, and microbial cells from sample solutions
• Pre-sterilized by gamma irradiation eliminates the need for additional sterilization before use
• Exceptional chemical resistance from strong carbon-fluorine bonds maintains integrity in caustic environments
• Membrane thickness of 80-140µm optimizes flow characteristics while ensuring consistent particle retention

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

SF18242 filters optimize your sterile analytical workflow with a balanced 20ml flow rate that accommodates both speed and precision requirements. Pre-sterilized packaging ensures immediate use while your samples maintain complete sterility at operating temperatures up to 60°C. Bubble point verification at 7.25psi using absolute ethyl alcohol confirms uniform pore distribution for reproducible sterile clarification results.
