Polyethersulfone (PES) Syringe Filters - SPEC18105

Featuring high-performance 0.45µm polyethersulfone membrane technology optimized for sample clarification applications across pharmaceutical, biotechnology, and analytical laboratory environments. Enhanced 25mm diameter design maximizes filtration surface area while maintaining rapid flow rates essential for processing larger sample volumes up to 100ml. Sterile polypropylene housing construction provides contamination-free sample processing with exceptional chemical resistance and thermal stability.

Key Polyethersulfone Membrane Characteristics

• Naturally hydrophilic surface eliminates pre-wetting requirements, streamlining sample preparation protocols in time-critical analytical workflows
• Stable operation throughout diverse chemical environments withstands exposure to organic solvents, aqueous buffers, and biological media
• Optimized 0.45µm pore dimensions effectively remove particulates and cellular debris while permitting efficient passage of dissolved analytes
• Low protein affinity preserves biomolecule integrity and maintains accurate concentration measurements throughout filtration processes
• Enhanced membrane durability resists tearing and provides consistent performance under elevated pressure differentials

Key Construction Characteristics

• Lightweight polypropylene housing delivers excellent chemical compatibility and maintains structural integrity at temperatures up to 80°C
• Standard 25mm diameter configuration optimizes yield by providing expanded filtration area for larger sample volumes and reduced processing time
• Double luer lock connection system creates secure, leak-resistant seals during automated dispensing and high-throughput laboratory operations
• Maximum operational pressure of 72.5psi enables efficient processing of viscous samples while preserving membrane performance

Designed to enhance your laboratory's analytical precision, these sterile filters combine reliable clarification performance with contamination-free processing capabilities.
