PVDF Hydrophobic Syringe Filter, 0.45µm, 4mm, Nonsterile, Luer-Lok, 200/pk SKU: LE-IWT-ES-10608

Featuring hydrophobic polyvinylidene fluoride (PVDF) membrane technology delivering ultra-low protein binding performance for precision sample preparation applications. PVDF syringe filters achieve the lowest protein adsorption among all membrane filter types, maximizing recovery rates for protein solutions, oligomers, and polymers. The unique concentric funnel-shaped barrel increases sample volume capacity while decreasing back pressure, accelerating your filtration processes during high-throughput analytical workflows.

Key PVDF Membrane Characteristics

Hydrophobic PVDF construction provides exceptional chemical stability similar to PTFE with superior protein recovery performance
0.45µm absolute pore rating ensures reliable particulate retention while maintaining optimal flow rates for small volume samples
Ultra-low protein binding characteristics maximize recovery of water-soluble oligomers, proteins, and biological macromolecules
Excellent chemical compatibility with organic solvents enables versatile filtration of hydrophobic substances and analytical samples
Nonsterile configuration optimized for routine laboratory sample preparation and chromatographic pre-filtration applications

Key Construction Characteristics

Compact 4mm diameter format accommodates micro-volume samples while minimizing sample loss and holdup volume
Luer-Lok® inlet connection with pressure fitting ensures secure attachment and prevents accidental disconnection during filtration
Ultrasonically bonded construction eliminates adhesive contamination while delivering superior mechanical integrity and reliability
Filter membrane type clearly inscribed on barrel for positive identification and traceability in multi-sample workflows
Polypropylene housing provides chemical resistance and dimensional stability across diverse solvent systems

LE-IWT-ES-10608 filters deliver excellent unit-to-unit and lot-to-lot reproducibility, ensuring consistent results across your analytical testing protocols. The concentric funnel design maximizes filtration efficiency while reducing the risk of membrane fouling, accelerating your sample throughput for HPLC, GC, and chromatographic applications. Outstanding chemical resistance to organic solvents combined with hydrophobic membrane characteristics transforms these filters into versatile tools for both aqueous protein solutions and nonpolar organic sample preparation, providing the flexibility your laboratory demands for diverse analytical workflows.
