PTFE Syringe Filters, 5.0um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk SKU: SF17400

Polytetrafluoroethylene (PTFE) Syringe Filters - SF17400

Featuring hydrophobic PTFE membrane technology optimized for coarse prefiltration of aggressive organic solvents and particulate-laden samples. A 5.0µm pore configuration delivers ultra-high flow rates 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 rapid prefiltration and clarification of heavily contaminated chemical 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 a 60°C continuous operating temperature
• 5.0µm pore size provides coarse prefiltration and removal of large particulates
• Autoclavable construction enables 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 compatibility accommodates all standard syringe configurations
• Standard 25mm diameter balances exceptional flow rate with practical handling characteristics
• 100µl holdup volume minimizes loss when filtering valuable reagents and limited samples

SF17400 syringe filters achieve exceptional 240ml/min flow rates through a 4.08cm² active membrane area, dramatically accelerating your prefiltration workflows even with heavily particulated samples. Outstanding flow characteristics minimize processing time while the 100ml throughput capacity handles your challenging samples requiring rapid clarification. Autoclave compatibility at 121°C transforms nonsterile units into validated sterile filters, providing flexibility for your applications demanding both absolute chemical resistance and coarse particle removal.

Hydrophobic

• Coarse prefiltration - Removal of large particulates, precipitates, and suspended solids from reaction mixtures and crude extracts
• Sample clarification - Initial filtration of heavily contaminated samples before fine filtration, protecting downstream 0.22 or 0.45µm filters
• Aggressive solvents - High-flow prefiltration of THF, DMF, DMSO, chloroform, and acetonitrile containing visible particulates
• Crystal removal - Rapid separation of crystallized products from mother liquors in organic synthesis and recrystallization procedures
• Catalyst recovery - Removal of heterogeneous catalysts, activated carbon, and solid-phase reagents from organic reaction mixtures
• Environmental samples - Prefiltration of soil extracts, sediment samples, and industrial waste streams before analytical testing
