PTFE Syringe Filter, Hydrophobic, Sterile, 0.22µm, 25mm, Luer-Lok, 100/Pk SKU: LE-IWT-ES10026

Featuring hydrophobic polytetrafluoroethylene (PTFE) membrane technology providing exceptional chemical resistance and sterile filtration performance for critical laboratory applications. Advanced hydrophobic PTFE construction delivers superior compatibility with organic solvents, acids, alkalies, and nonpolar liquids while maintaining 100% integrity testing compliance with ISO 9002 manufacturing standards. Gamma radiation sterilization ensures certified sterile, nonpyrogenic, and noncytotoxic performance with exceptional reliability for pharmaceutical sample preparation, HPLC mobile phase filtration, and chromatography solvent degassing.

Key PTFE Membrane Characteristics

Hydrophobic surface chemistry naturally repels aqueous solutions while optimizing flow rates for organic solvent and gas filtration applications
0.22µm pore size delivers absolute bacterial retention while maintaining optimal flow characteristics for viscous organic samples
Superior chemical resistance withstands aggressive solvents, acids, and bases without membrane degradation or particle release
Low protein binding characteristics minimize sample loss during pharmaceutical and biological sample processing protocols
Maximum operating temperature of 60°C provides thermal stability for heated sample processing while maintaining housing integrity

Key Construction Characteristics

25mm diameter configuration maximizes filtration area while accommodating standard laboratory syringe systems and automated sampling equipment
Dual Luer-Lok and Luer Slip connection compatibility ensures secure attachment to diverse syringe types and eliminates connection failures
Ultrasonically bonded construction eliminates adhesive contamination while delivering exceptional membrane-to-housing seal integrity
Concentric funnel-shaped barrel design increases sample volume capacity while reducing back pressure during high-viscosity sample processing
Bidirectional membrane support with clearly printed membrane identification ensures proper orientation and eliminates filtration errors

LE-IWT-ES10026 filters achieve exceptional unit-to-unit reproducibility ensuring consistent analytical results across extended research campaigns and quality control protocols. Outstanding versatility enables pre-wetting with alcohol for aqueous sample compatibility, transforming hydrophobic characteristics for ion chromatography applications requiring fine particle removal. Individual blister packaging maintains sterility integrity while streamlining contamination control protocols, providing validated performance assurance for your most critical aerosol sampling, vacuum pump line protection, and moisture barrier venting applications demanding both chemical compatibility and certified sterile processing capabilities.
