PTFE Syringe Filters, 0.22 um, 13mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF14472

Polytetrafluoroethylene (PTFE) Syringe Filters - SF14472

Featuring hydrophobic PTFE membrane technology in sterile packaging for aggressive organic solvent filtration requiring microbiological control. A 0.22µm pore configuration ensures complete bacterial removal while maintaining absolute chemical inertness to concentrated acids, bases, and challenging solvents. Tisch Scientific combines ultra-resistant PTFE membranes with compact 13mm construction to deliver sterile filtration 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 handles all organic solvents, acids, and bases without degradation
• Superior thermal stability maintains performance at 60°C continuous operating conditions
• 0.22µm absolute pore rating guarantees complete bacterial and microorganism removal
• Sterile individual packaging ensures contamination-free filtration for critical applications

Key Construction Characteristics

• Polypropylene housing provides chemical resistance while withstanding 87psi burst pressure
• Dual Luer-Lok/Luer Slip connections ensure universal compatibility with standard syringes
• Compact 13mm diameter optimizes performance for small volume sterile sample processing
• 10µl minimal holdup volume maximizes recovery of precious sterile reagents

SF14472 syringe filters deliver consistent 5.5ml/min flow rates through a 1.09cm² active membrane area, providing controlled sterile filtration for your most aggressive chemical applications. Minimal 10µl holdup volume ensures maximum recovery of your valuable samples while sterile packaging eliminates contamination risks. Certified sterile units maintain 17.4psi bubble point integrity in absolute ethyl alcohol, guaranteeing reliable bacterial retention for your critical applications requiring both absolute chemical resistance and validated sterility assurance.
