PES Syringe Filter, Hydrophilic, 0.22µm, 4mm, Luer-Lok, Nonsterile, 200/Pack SKU: LE-IWT-ES-10609

Featuring high porosity asymmetric pore structure polyethersulfone membrane technology delivering exceptional flow rates and minimal protein binding for demanding sample preparation applications. Hydrophilic 0.22µm filtration achieves reliable particle retention while maintaining rapid processing speeds essential for HPLC, GC, and ion chromatography workflows. Ultrasonically bonded polypropylene housing with precision Luer-Lok® connections ensures leak-free performance during high-pressure sample processing operations.

Key PES Membrane Characteristics

• Intrinsically low protein binding characteristics maximize sample recovery for biological and pharmaceutical applications requiring pristine analyte preservation
• Asymmetric pore structure delivers superior flow rates while maintaining absolute 0.22µm particle retention for reliable sample clarification
• Exceptional compatibility with acids, bases, and oxidizer solutions expands analytical versatility across diverse sample matrices
• Maximum recommended operating temperature for the syringe filters when used with compatible fluids is 60°C
• Hydrophilic surface chemistry eliminates wetting agents and pre-rinsing steps, accelerating your sample preparation protocols

Key Construction Characteristics

• Compact 4mm diameter configuration optimizes dead volume while providing adequate filtration area for small-volume analytical samples
• Precision-molded polypropylene housing withstands moderate pressures while maintaining dimensional stability throughout extended processing cycles
• Ultrasonically welded construction eliminates adhesive contamination risks and ensures consistent seal integrity under varying pressure conditions
• Female Luer-Lok® inlet and male Luer slip outlet provide secure syringe connections while accommodating standard laboratory hardware configurations
• Color-coded identification system enables rapid membrane type verification, reducing selection errors during multi-sample processing workflows

These filters achieve optimal performance in clarification of protein laden solutions, tissue culture media sterilization, and processing immunoassay and nucleic acid hybridization samples. Low extractables profile maintains sample integrity for critical trace analysis applications, while the wide chemical compatibility spectrum accommodates diverse solvent systems commonly encountered in pharmaceutical and biotechnology laboratories. 200-unit packaging delivers cost-effective convenience for high-throughput analytical operations demanding consistent filtration performance and reliable sample preparation reproducibility.
