PVDF Syringe Filter, Glass Fiber Prefilter, 0.22µm, 25mm, Luer-Lok, Nonsterile, 100/Pk SKU: LE-IWT-ES10221

Featuring hydrophobic PVDF membrane technology with integrated glass microfiber prefilter delivering exceptional throughput capacity for protein solutions and organic solvent filtration applications. The dual-layer construction with glass fiber prefilter reduces particle loading on the primary membrane, extending service life while preventing back pressure buildup. Low protein binding characteristics and chemical resilience to acids, bases, and organic solvents optimize recovery rates for biomolecule processing and HPLC sample preparation protocols.

Key PVDF Membrane Characteristics

Hydrophobic PVDF construction with low protein binding properties maximizes recovery of proteins, peptides, and other biomolecules
Compatible with HPLC and GC sample preparation, chromatography buffers, and mobile phase filtration applications
Excellent chemical compatibility with alcohols, weak acids, and organic solvents while maintaining high flow rates
Low UV-absorbing extractables certification ensures minimal interference in analytical measurements
0.22µm pore size provides reliable particulate removal and clarification for sterile filtration requirements

Key Construction Characteristics

Integrated glass microfiber prefilter increases total throughput capacity for high-solids samples compared to standard membrane-only designs
Luer-Lok® and pressure fitting compatibility delivers secure connections preventing sample loss during processing
Concentric funnel-shaped barrel design increases filtration volume while decreasing back pressure for faster processing
Ultrasonic bonding construction ensures reliable seal integrity without adhesive contamination risks
Clear filter media type inscription on barrel enables rapid identification and prevents cross-contamination errors

LE-IWT-ES10221 filters achieve consistent unit-to-unit and lot-to-lot reproducibility, accelerating your analytical workflows while maintaining validation standards for pharmaceutical and biotechnology applications. Outstanding versatility for enzyme and protein solution sterilization, tissue culture media preparation, and immunoassay sample clarification transforms these filters into comprehensive processing tools. Nonsterile design with 100-filter packaging maximizes cost efficiency for high-volume laboratory operations requiring reliable filtration performance without sterility validation overhead.
