Polyethersulfone PES Syringe Filters, 0.45um, 30mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF18255

Polyethersulfone (PES) Syringe Filters - SF18255

Featuring pre-sterilized high-capacity polyethersulfone membrane technology with 0.45µm pore size engineered for efficient clarification of larger sample volumes. Ready-to-use sterile 30mm format delivers exceptional 80ml flow rates and 110ml throughput capacity for rapid particulate removal in pharmaceutical and biotechnology applications. Tisch Scientific combines hydrophilic PES membranes with integrated glass fiber prefiltration to maximize flow rates while maintaining consistent clarification performance in demanding laboratory workflows requiring immediate aseptic processing.

Key Polyethersulfone (PES) Membrane Characteristics

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

Key Construction Characteristics

• Large 30mm diameter format supporting high-volume sample processing needs
• Integrated glass fiber prefilter protecting the membrane from particulate fouling
• Holdup volume of 100µL ensuring efficient recovery despite larger format
• Universal Luer-Lok/Luer Slip connectivity compatible with all syringe types

SF18255 syringe filters maintain exceptional flow rates of 80ml through an expanded 4.9cm² active filtration area, maximizing your workflow efficiency for high-volume clarification applications. A bubble point of 31.91psi validates membrane integrity for applications requiring documented performance while supporting throughput volumes up to 110ml for demanding laboratory processes. Pre-sterilized individual packaging eliminates preparation time while ensuring immediate use in aseptic applications, maintaining operational capability up to 60°C for your critical clarification requirements.
