PES Syringe Filter, Sterile, 0.22µm, 13mm, Hydrophilic Polyethersulfone, Luer-Lock, 100/Pk SKU: LE-IWT-ES10071

Featuring hydrophilic polyethersulfone membrane technology delivering exceptional flow rates and intrinsically low protein binding for sterile filtration applications. The 0.22µm pore size configuration provides reliable bacterial retention while maintaining 60°C maximum operating temperature compatibility. Individual blister packaging with Luer-Lock® connections ensures sterility integrity and universal syringe compatibility for critical laboratory protocols.

Key PES Membrane Characteristics

• High porosity asymmetric pore structure maximizes throughput while maintaining sterile filtration efficiency
• Intrinsically low protein binding characteristics ensure maximum sample recovery for biological applications
• Exceptional compatibility with acids, bases, and oxidizers expands chemical application flexibility
• Hydrophilic membrane surface eliminates wetting requirements and accelerates filtration startup
• pH stability range of 3-12 accommodates diverse analytical and biological sample types

Key Construction Characteristics

• Medical-grade polypropylene housing with ultrasonically bonded construction prevents leakage under pressure
• Female Luer-Lock® inlet and male Luer slip outlet provide secure, leak-free syringe connections
• 13mm membrane diameter optimized for small volume samples while maintaining adequate filtration area
• Individual blister packaging maintains sterility integrity until point of use
• Filter media type clearly inscribed on barrel for positive identification during procedures

These sterile PES syringe filters deliver reliable 0.22µm bacterial retention with minimal holdup volume, accelerating your sample processing while maximizing recovery yields. Ideal for sterilization of tissue culture media, protein solutions, and aqueous biological samples, the low-binding membrane technology prevents sample loss during filtration of valuable biological materials. Low extractables profile makes these filters suitable for HPLC sample preparation, while the broad chemical compatibility supports diverse analytical protocols requiring both sterility assurance and sample integrity preservation.
