Sterile PP Syringe Filter, 0.22µm, 25mm, Hydrophobic Membrane, Luer-Lok, 100/Pk SKU: LE-IWT-ES10135

Featuring hydrophobic polypropylene membrane technology delivering absolute bacterial retention for small-volume sterile filtration applications requiring economical operation. The 0.22µm pore size achieves 99.99% sterilization effectiveness validated to remove bacteria and microorganisms, while 20 µL holdup volume minimizes sample loss. Ultrasonically bonded construction with individually blister-packed sterile presentation delivers reliable processing of aqueous and alcohol-based solutions requiring validated analytical protocols.

Key Polypropylene Membrane Characteristics

• Naturally hydrophobic surface chemistry with broad chemical compatibility from pH 1-14, offering excellent resistance to acids and bases
• Low protein binding with minimal extractables ensures sample integrity for critical analytical applications
• Autoclavable construction withstands 121°C for 15 minutes, enabling pre-sterilization protocols
• 0.22µm pore configuration provides absolute bacterial retention meeting sterilization-grade filtration standards
• Validated bacterial removal supports pharmaceutical and research applications demanding sterile conditions

Key Construction Characteristics

• Luer-Lok inlet with pressure fitting ensures leak-tight syringe connection and secure sample processing
• Rugged polypropylene housing construction provides chemical resistance and handling durability
• Individual blister packaging maintains sterility until point-of-use, eliminating contamination risks
• Color-coded identification system enables rapid filter selection and reduces laboratory workflow errors
• 25mm diameter optimized for HPLC sample preparation with weak solids and small sample volumes

LE-IWT-ES10135 filters achieve exceptional sample throughput optimized for 1-10mL processing volumes, accelerating your analytical workflows while maintaining sterile filtration performance. Outstanding wettability characteristics support both aqueous solutions and clarification applications, often serving as prefiltration ahead of membrane filters. Economical sterile filtration solution delivers reliable 0.22µm bacterial retention at significantly lower cost than premium membrane alternatives, transforming these filters into validated reference-grade media for pharmaceutical products and research applications demanding both sterile conditions and budget-conscious operation.
