PVDF Syringe Filter w/ Glass Fiber Prefilter, 0.45µm, 13mm, Nonsterile, Luer-Lok, 100/Pk SKU: LE-IWT-ES10220

Featuring advanced PVDF membrane technology with integrated glass microfiber prefilter delivering exceptional filtration performance for protein solutions, water-soluble oligomers, and polymers. The glass fiber prefilter extends filter service life by reducing particle loading on the primary membrane while maintaining optimal flow characteristics. PVDF construction provides extremely low protein binding with hydrophobic interactions similar to PTFE, making it ideal for demanding biological applications requiring maximum sample recovery.

Key PVDF Membrane Characteristics

0.45µm pore size delivers precise particle retention while maintaining high flow rates for efficient sample processing
Glass microfiber prefilter increases loading capacity and prevents premature membrane blocking during high-volume filtrations
Excellent chemical compatibility with aggressive acids, alcohols, and organic solvents expands application versatility
Hydrophobic surface chemistry provides PTFE-like interactions for superior performance with water-soluble compounds
Ultra-low protein binding minimizes sample loss and maintains analyte integrity in biological applications

Key Construction Characteristics

13mm diameter configuration optimized for 0-10ml sample volumes with minimal hold-up volume
Luer-Lok® inlet connection ensures secure attachment and prevents accidental disconnection during operation
Concentric funnel-shaped barrel design increases internal volume while decreasing back pressure for enhanced flow
Ultrasonic bonding construction delivers reliable seal integrity and eliminates potential contamination pathways
Clear filter media identification inscribed on barrel provides immediate membrane type verification

LE-IWT-ES10220 filters achieve consistent unit-to-unit and lot-to-lot reproducibility, ensuring reliable results across your analytical protocols. Outstanding performance with protein solutions, nucleic acid samples, and biological fluids makes these filters essential for HPLC sample preparation, chromatography applications, and western blotting protocols. The integrated prefilter technology maximizes your filtration efficiency while the nonsterile format provides cost-effective solutions for routine laboratory applications where sterility is not required.
