Thumbnail Filmstrip of PTFE Syringe Filters, 0.45um, 13mm, Luer-Lok/Luer Slip, Sterile, 100/Pk Images
Polytetrafluoroethylene (PTFE) Syringe Filters - SF14473
Featuring hydrophobic PTFE membrane technology in sterile packaging for aggressive organic solvent clarification requiring contamination-free processing. A 0.45µm pore configuration delivers efficient particulate removal while maintaining complete chemical inertness to concentrated acids, bases, and challenging reagents. Tisch Scientific combines ultra-resistant PTFE membranes with compact 13mm construction to provide sterile clarification of chemically aggressive samples in small volumes.
Key Polytetrafluoroethylene (PTFE) Membrane Characteristics
- Hydrophobic membrane requires alcohol pre-wetting for aqueous solution compatibility
- Universal chemical resistance withstands all organic solvents, acids, and bases without degradation
- Exceptional thermal stability maintains integrity at 60°C continuous operating conditions
- 0.45µm pore size provides reliable clarification and coarse particulate removal
- Sterile individual packaging ensures contamination-free filtration for sensitive applications
Key Construction Characteristics
- Polypropylene housing delivers chemical resistance while withstanding 87psi burst pressure
- Dual Luer-Lok/Luer Slip design accommodates all standard syringe configurations
- Compact 13mm diameter maximizes efficiency for small volume sterile sample processing
- 10µl minimal holdup volume ensures maximum recovery of precious sterile reagents
SF14473 syringe filters achieve 11ml/min flow rates through a 1.09cm² active membrane area, balancing filtration speed with thorough particulate removal for your challenging sterile applications. Minimal 10µl holdup volume maximizes your sample recovery while sterile packaging eliminates contamination risks throughout processing. Certified sterile units maintain 7.25psi bubble point integrity in absolute ethyl alcohol, ensuring reliable performance for your critical applications requiring both absolute chemical resistance and validated sterility assurance.
