Polyethersulfone PES Syringe Filters, 0.22um, 17mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF18253

Polyethersulfone (PES) Syringe Filters - SF18253

Featuring pre-sterilized polyethersulfone membrane technology with sterilizing-grade 0.22µm pore size optimized for bacterial filtration in intermediate-volume applications. Ready-to-use sterile 17mm format delivers complete bacteria removal while balancing throughput efficiency with economical filter usage for routine sterile processing needs. Tisch Scientific combines hydrophilic PES membranes with integrated glass fiber prefiltration to ensure reliable sterile filtration performance in pharmaceutical quality control, cell culture, and analytical workflows requiring immediate aseptic processing.

Key Polyethersulfone (PES) Membrane Characteristics

• Naturally hydrophilic membrane enabling immediate filtration without pre-wetting
• Sterilizing-grade 0.22µm pore size, ensuring complete bacterial retention
• Minimal protein binding, preserving biological activity and sample integrity
• Membrane thickness of 100-160µm, providing consistent filtration performance
• Superior chemical compatibility with aqueous and mild organic solutions

Key Construction Characteristics

• Intermediate 17mm diameter format bridging small and standard volume needs
• Integrated glass fiber prefilter protecting the membrane from particulate fouling
• Low holdup volume of 20µL ensures efficient recovery of valuable samples
• Universal Luer-Lok/Luer Slip connectivity accommodating all syringe types

SF18253 syringe filters maintain optimal flow rates of 13ml through a 1.65cm² active filtration area, perfectly scaled for your intermediate-volume sterile filtration requirements. A bubble point of 43.51psi validates membrane integrity for applications requiring documented performance in regulated environments. Pre-sterilized individual packaging eliminates preparation time while ensuring immediate use in aseptic applications, maintaining operational capability up to 60°C for your critical sterile filtration needs.
