Polyethersulfone (PES) Syringe Filters - SF14504

Featuring sterile-packaged polyethersulfone membrane technology optimized for small-volume bacterial filtration applications. Pre-sterilized 13mm format delivers immediate sterile filtration capability without additional preparation steps, ideal for precious samples and limited-volume applications. Tisch Scientific engineers compact filtration solutions combining 0.22µm sterilizing-grade membranes with efficient polypropylene housing construction for reliable performance in microbiological and pharmaceutical quality control.

Key Polyethersulfone (PES) Membrane Characteristics

• Naturally hydrophilic membrane requiring no pre-wetting for immediate filtration
• Sterilizing-grade 0.22µm pore size, ensuring complete bacteria removal
• Minimal protein binding preserving biological activity in sensitive samples
• Membrane thickness of 100-160µm, providing consistent retention characteristics
• Broad chemical compatibility supporting aqueous and mild organic solutions

Key Construction Characteristics

• Compact 13mm diameter design optimized for small-volume sample processing
• Integrated PP prefilter enhances throughput and protects the primary membrane
• Ultra-low holdup volume of 10µL, maximizing recovery of valuable samples
• Universal Luer-Lok/Luer Slip connectivity compatible with standard syringes

SF14504 syringe filters provide controlled flow rates of 7ml through a 1.09cm² filtration area, perfectly scaled for your small-volume applications while maintaining sterilizing efficiency. A bubble point of 43.51psi ensures membrane integrity verification for validated sterile filtration processes in regulated environments. Pre-sterilized packaging eliminates preparation time and ensures immediate readiness for aseptic processing, while maintaining operational temperatures up to 60°C for routine filtration applications.
