Polyethersulfone (PES) Syringe Filters - SF14505

Featuring pre-sterilized polyethersulfone membrane technology with 0.45µm pore size optimized for clarification applications in small-volume sample processing. Ready-to-use sterile packaging eliminates preparation steps while delivering reliable particulate removal for precious biological samples requiring immediate filtration capability. Tisch Scientific engineers compact filtration solutions combining hydrophilic PES membranes with 13mm format to ensure consistent clarification performance in pharmaceutical quality control, cell culture, and analytical workflows.

Key Polyethersulfone (PES) Membrane Characteristics

• Naturally hydrophilic membrane providing instantaneous wet-out without pre-treatment
• Clarification-grade 0.45µm pore size removes cells, debris, and particulates
• Minimal protein binding preserves sample integrity and biological activity
• Membrane thickness of 100-160µm, ensuring consistent retention characteristics
• Superior chemical compatibility with aqueous solutions and mild organics

Key Construction Characteristics

• Compact 13mm diameter design optimized for precious small-volume samples
• Integrated PP prefilter enhances throughput and protects the primary membrane
• Ultra-low holdup volume of 10µL, maximizing recovery of valuable materials
• Universal Luer-Lok/Luer Slip connectivity accommodating all syringe types

SF14505 syringe filters maintain optimal flow rates of 14.5ml through a 1.09cm² active filtration area, perfectly scaled for your small-volume clarification needs while maximizing processing efficiency. A bubble point of 31.91psi validates membrane integrity for applications requiring documented performance in regulated environments. Pre-sterilized individual packaging ensures immediate use in aseptic applications, eliminating preparation time while maintaining operational capability up to 60°C for your most critical clarification requirements.
