Polypropylene Syringe Filter, 0.22 µm, 25mm, Hydrophobic, Nonsterile, Luer-Lok, 100/Pk SKU: LE-IWT-ES10130

Featuring hydrophobic polypropylene membrane technology delivering highly efficient particle retention and consistent sterile filtration performance for analytical sample preparation and HPLC preprocessing applications. The 0.22 µm membrane ensures reliable bacterial retention while the polypropylene housing provides wide chemical compatibility with organic solvents, acids, bases, alcohols and esters. Dual Luer-Lok connection design with ultrasonically bonded construction eliminates adhesive contamination risks and maximizes sample purity for critical analytical workflows.

Key Polypropylene Membrane Characteristics

Hydrophobic membrane with heavy chemical resistance enables processing of organic solvents and aggressive chemical solutions without membrane degradation
0.22 micron pore size effectively removes even the smallest particles from samples, providing absolute bacterial retention for sterile filtration applications
High flow rate performance accelerates sample processing while maintaining filtration integrity throughout extended use cycles
Imported high-performance filter membrane with stable product quality and good reproducibility ensures consistent batch-to-batch performance
Ultrasonically bonded construction eliminates organic adhesives and potential leachable contamination in sensitive analytical applications

Key Construction Characteristics

25mm diameter with optimized filtration area supports efficient processing of small to medium-volume samples up to 10mL
Polypropylene housing with thermal stability withstands laboratory temperature variations while maintaining dimensional integrity
Dual Luer-Lok and pressure fitting compatibility provides secure, leak-tight connections with standard laboratory syringes
Filter media type clearly inscribed on barrel enables easy identification and prevents cross-contamination between different membrane types
Concentric funnel-shaped barrel design increases sample volume capacity while decreasing back pressure for improved processing efficiency

These nonsterile polypropylene filters achieve exceptional unit-to-unit and lot-to-lot reproducibility, delivering validated performance consistency that accelerates your analytical workflows. HPLC sample preparation applications benefit from the membrane's low extractable characteristics and broad solvent compatibility, while environmental analysis workflows leverage the superior chemical resistance for processing aggressive sample matrices. The 100-filter bulk packaging maximizes laboratory efficiency while providing cost-effective filtration solutions for high-throughput analytical laboratories requiring dependable particle removal and sample clarification.
