PTFE Syringe Filters, 0.45um, 25mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF14475

Polytetrafluoroethylene (PTFE) Syringe Filters - SF14475

Featuring hydrophobic PTFE membrane technology in sterile packaging for the clarification of aggressive organic solvents. The 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 optimized 25mm construction to provide pre-sterilized clarification 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 handles all organic solvents, acids, and bases without degradation
• Exceptional thermal stability maintains performance at 60°C continuous operating conditions
• 0.45µm pore size provides reliable clarification and coarse particulate removal (Note: Not for sterilizing-grade filtration)
• Pre-sterilized individual packaging prevents the introduction of contamination during sensitive applications

Key Construction Characteristics

• Polypropylene housing delivers chemical resistance while withstanding 87psi burst pressure
• Dual Luer-Lok/Luer Slip compatibility accommodates all standard syringe configurations
• Standard 25mm diameter optimizes flow rate and capacity for routine clarification
• 100µL holdup volume minimizes loss when filtering valuable reagents

SF14475 syringe filters achieve exceptional 35ml/min flow rates through a 4.08cm² active membrane area, accelerating your sample processing even with viscous organic solvents. Outstanding 100ml throughput capacity maximizes your laboratory efficiency when filtering challenging matrices. Pre-sterilized units maintain 7.25psi bubble point integrity in absolute ethyl alcohol, ensuring reliable performance for your critical applications demanding absolute chemical resistance and low-bioburden processing.
