PVDF Tri-Layer Syringe Filter w/ GF/PP Prefilter, 0.22µm, 25mm, Nonsterile, Luer-Lok SKU: LE-IWT-ES10406

Featuring advanced tri-layer PVDF membrane technology delivering exceptional filtration performance with significantly enhanced loading capacity for challenging sample processing applications. A glass microfiber and polypropylene prefilter construction prevents build-up of back pressure typically caused by blocking of unprotected membranes, while the 0.22µm hydrophobic PVDF final layer provides reliable particulate retention and sterilization-grade filtration. The unique concentric funnel-shaped barrel design increases sample volume capacity while decreasing back pressure, accelerating your filtration workflows with superior consistency.

Key PVDF Membrane Characteristics

Lowest protein adsorption characteristics among syringe filter technologies maximize recovery of valuable biological samples
High flow rates combined with low protein binding capabilities deliver optimal performance for HPLC and analytical applications
Hydrophobic 0.22µm pore size provides sterilization-grade filtration for organic solvents and biological solutions
Maximum operating temperature of 60°C maintains membrane integrity during elevated temperature processing
Outstanding chemical compatibility with alcohols, weak acids, and biomolecules while avoiding strong bases

Key Construction Characteristics

Tri-layer configuration with glass microfiber/polypropylene prefilters dramatically extends filter service life and sample throughput
Ultrasonically bonded construction ensures leak-proof performance and eliminates contamination risks during critical filtrations
Premium polypropylene housing with wide chemical compatibility and overmolded design for higher operating pressures
Luer-Lok inlet/outlet connections offer leak-tight syringe attachment with secure threaded engagement
Clear filter media identification inscribed on barrel eliminates selection errors and ensures proper application matching

LE-IWT-ES10406 filters achieve exceptional unit-to-unit and lot-to-lot reproducibility, delivering validated performance consistency essential for your analytical protocols and quality control applications. The innovative concentric funnel barrel geometry increases filtration volume capacity while optimizing flow dynamics, making these filters ideal for high-throughput sample preparation in chromatography, biological research, and pharmaceutical development where both loading capacity and membrane performance are critical to successful outcomes.
