Thumbnail Filmstrip of PTFE Syringe Filter, 0.45 µm, 25 mm, Luer-Lok/Luer Slip, Non-Sterile, 100/Pk Images
Polytetrafluoroethylene (PTFE) Syringe Filters - SF14469
Featuring hydrophobic PTFE membrane technology providing unmatched chemical resistance for aggressive organic solvent clarification applications. A 0.45µm pore configuration delivers efficient particulate removal while maintaining absolute inertness to concentrated acids, bases, and challenging reagents. Tisch Scientific engineers combine ultra-resistant PTFE membranes with optimized 25mm construction for reliable processing of chemically aggressive samples requiring superior flow characteristics.
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
- Exceptional thermal stability maintains integrity at 60°C continuous operating temperature
- 0.45µm pore size provides reliable clarification and coarse particulate removal
- Autoclavable construction enables sterilization at 121°C for validated analytical protocols
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 laboratory applications
- 100µl holdup volume minimizes loss when processing valuable reagents and limited samples
SF14469 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 requiring chemical resistance. Autoclave compatibility at 121°C transforms nonsterile units into validated sterile filters, providing flexibility for your critical applications demanding both absolute chemical inertness and certified sterility assurance.
