PTFE Syringe Filters, 0.22 um, 25mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF14474

Polytetrafluoroethylene (PTFE) Syringe Filters - SF14474

Featuring hydrophobic PTFE membrane technology in sterile packaging for aggressive organic solvent filtration requiring complete microbiological control. A 0.22µm pore configuration ensures sterile-grade bacterial removal while maintaining absolute chemical inertness to concentrated acids, bases, and challenging solvents. Tisch Scientific combines ultra-resistant PTFE membranes with optimized 25mm construction to deliver certified sterile filtration of chemically aggressive samples at production scale.

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
• Superior thermal stability maintains integrity at 60°C continuous operating temperature
• 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
• Standard 25mm diameter balances flow rate with capacity for routine sterile processing
• 100µl holdup volume minimizes loss when filtering valuable sterile reagents

SF14474 syringe filters maintain consistent 18ml/min flow rates through a 4.08cm² active membrane area, providing controlled sterile filtration for your most aggressive chemical applications. Exceptional 100ml throughput capacity maximizes your laboratory efficiency when processing challenging solvents requiring certified sterility. Pre-sterilized units maintain 17.4psi bubble point integrity in absolute ethyl alcohol, ensuring reliable bacterial retention for your critical applications demanding both absolute chemical resistance and validated microbiological safety.
