PTFE Syringe Filters, 0.22 um, 13mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk SKU: SF14466

Polytetrafluoroethylene (PTFE) Syringe Filters - SF14466

Featuring hydrophobic PTFE membrane technology delivering unmatched chemical resistance for aggressive organic solvent filtration applications. A 0.22µm pore configuration provides sterile-grade bacterial removal while maintaining complete inertness to concentrated acids, bases, and challenging solvents. Tisch Scientific combines ultra-resistant PTFE membranes with compact 13mm construction for efficient small-volume filtration of chemically aggressive samples.

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 ensures complete bacterial and microorganism removal
• Autoclavable construction enables sterilization at 121°C for validated analytical protocols

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 sample processing
• 10µl minimal holdup volume maximizes recovery of precious reagents and limited samples

SF14466 syringe filters deliver consistent 5.5ml/min flow rates through a 1.09cm² active membrane area, providing controlled filtration for your most aggressive chemical applications requiring sterility. Minimal 10µl holdup volume ensures maximum recovery of your valuable samples, while the compact design reduces solvent consumption during pre-wetting procedures. Autoclave compatibility at 121°C transforms nonsterile units into validated sterile filters, supporting your critical applications requiring both absolute chemical resistance and certified bacterial retention.

Hydrophobic

• Aggressive Solvent Sterilization - Removes bacterial contamination from DMF, DMSO, THF, and chlorinated solvents in pharmaceutical synthesis workflows
• Non-Aqueous Pharmaceutical Sterilization - Provides complete bacterial removal from pharmaceutical preparations dissolved in organic solvent systems
• HPLC Sample Preparation - Protects chromatography columns from particulate contamination while sterilizing organic mobile phases for analytical testing
• Strong Acid Filtration - Safely processes concentrated HCl, H₂SO₄, and HNO₃ without membrane degradation for analytical and synthesis applications
• Air and Gas Venting - Maintains a hydrophobic barrier preventing liquid breakthrough in gas lines while allowing efficient air passage
• Protein Precipitation Clarification - Removes precipitated proteins following TCA or organic solvent precipitation in sample preparation protocols
