Polyethersulfone (PES) Syringe Filters - SF14506

Featuring pre-sterilized polyethersulfone membrane technology delivering immediate sterile filtration capability for critical biological applications. Ready-to-use packaging eliminates preparation steps while maintaining sterilizing-grade 0.22µm retention performance essential for pharmaceutical and biotechnology workflows. Tisch Scientific integrates proven PES membrane chemistry with robust polypropylene housing to ensure consistent bacteria removal in cell culture, pharmaceutical quality control, and research applications requiring validated sterility assurance.

Key Polyethersulfone (PES) Membrane Characteristics

• Naturally hydrophilic membrane providing instantaneous wet-out without pre-treatment
• Sterilizing-grade 0.22µm pore size, ensuring complete bacterial retention
• Ultra-low protein binding preserving biological activity and sample integrity
• Membrane thickness of 100-160µm delivering consistent filtration performance
• Broad chemical compatibility supporting aqueous solutions and mild organics

Key Construction Characteristics

• Durable polypropylene housing rated for 87psi maximum operating pressure
• Integrated PP prefilter extending primary membrane life and improving throughput
• Holdup volume of 100µL, minimizing loss of valuable biological samples
• Universal Luer-Lok/Luer Slip design accommodating all standard syringe types

SF14506 syringe filters maintain optimal flow rates of 24ml through a 4.08cm² active filtration area, maximizing your laboratory productivity without compromising sterility assurance. A bubble point of 43.51psi validates membrane integrity for critical applications requiring documented performance verification in regulated environments. Pre-sterilized individual packaging eliminates preparation steps and ensures immediate use in aseptic applications while maintaining operational capability up to 60°C.
