Thumbnail Filmstrip of PTFE Syringe Filters, 0.45um, 13mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk Images
Polytetrafluoroethylene (PTFE) Syringe Filters - SF14467
Featuring hydrophobic PTFE membrane technology providing universal chemical resistance for aggressive organic solvent clarification applications. A 0.45µm pore configuration delivers efficient particulate removal while maintaining complete inertness to concentrated acids, bases, and challenging solvents. Tisch Scientific integrates ultra-resistant PTFE membranes with compact 13mm construction to optimize 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 handles all organic solvents, acids, and bases without degradation
- Exceptional thermal stability maintains performance at 60°C continuous operation
- 0.45µm pore size provides reliable clarification and coarse particulate removal
- Autoclavable construction allows sterilization at 121°C for validated protocols
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 sample processing
- 10µl minimal holdup volume ensures maximum recovery of precious reagents
SF14467 syringe filters achieve 11ml/min flow rates through a 1.09cm² active membrane area, balancing filtration speed with thorough particulate removal for your challenging chemical applications. Minimal 10µl holdup volume maximizes your sample recovery while the compact design reduces solvent consumption during necessary pre-wetting procedures. Autoclave compatibility at 121°C provides flexibility for your applications requiring sterility, transforming nonsterile units into validated sterile filters for critical organic solvent filtration protocols.
