Hydrophilic Polytetrafluoroethylene (PTFE) Syringe Filters - SF17506

Featuring hydrophilic-treated PTFE membrane technology with 0.22µm pore size for sterile filtration of micro-volume aqueous samples without pre-wetting requirements. The ultra-compact 4mm diameter format delivers 0.125cm² filtration area optimized for precious analytical specimens where sample conservation is critical. An integrated polypropylene prefilter extends membrane life by capturing coarse particulates before they reach the primary PTFE layer, enabling consistent performance across challenging sample matrices. Your laboratory maximizes sample recovery with just 1µL holdup volume while maintaining sterile filtration capability for bacterial removal from buffers, reagents, and biological solutions.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Hydrophilic surface treatment eliminates pre-wetting procedures, enabling immediate processing of aqueous samples, buffers, and biological solutions without alcohol preparation steps
• Sterile-grade 0.22µm pore size removes bacteria and provides validated sterile filtration for cell culture media, pharmaceutical solutions, and microbiological applications
• Exceptional chemical resistance maintains membrane integrity when filtering aggressive solvents, strong acids, bases, and reactive organic compounds throughout analytical workflows
• Low protein binding characteristics preserve sample composition and prevent adsorptive losses during filtration of enzyme solutions, antibodies, and protein formulations
• Integrated polypropylene prefilter captures large particles and extends membrane life when processing samples with high particulate loads or cellular debris

Key Construction Characteristics

• Polypropylene housing construction provides broad chemical compatibility and autoclave capability at 121°C for user sterilization protocols when needed
• Ultra-compact 4mm diameter with 0.125cm² filtration area designed specifically for micro-volume analytical samples requiring maximum recovery efficiency
• Minimal 1µL holdup volume preserves precious samples and ensures maximum recovery of expensive reagents, reference standards, and limited biological specimens
• Dual Luer-Lok and Luer Slip compatibility accommodates various micro-syringe configurations for precise control during small-volume sample processing operations

Engineered for your most demanding micro-volume sterile filtration requirements, these specialty filters combine PTFE's exceptional chemical resistance with hydrophilic convenience for immediate aqueous sample processing. You gain maximum sample recovery through ultra-low holdup volume design while the integrated prefilter protects the membrane from particulate fouling. Autoclavable construction supports your sterilization protocols, and robust 87psi burst pressure ensures reliable performance across diverse analytical and pharmaceutical applications.
