PTFE Syringe Filter, Hydrophobic, Nonsterile - 0.45µm, 4mm - 200/pk SKU: LE-IWT-ES-10604

Featuring hydrophobic polytetrafluoroethylene membrane technology delivering excellent chemical compatibility and superior flow performance for demanding analytical applications. The 0.45µm pore configuration provides reliable clarification of organic solvents while maintaining 60°C maximum operating temperature for elevated temperature processing. Ultra-resistant PTFE construction with very low extractables delivers contamination-free results for HPLC sample preparation and chromatography mobile phase filtration requiring validated analytical protocols.

Key PTFE Membrane Characteristics

• Hydrophobic membrane with the highest chemical compatibility rating resists all organic solvents, acids, and bases without degradation
• 0.45µm absolute retention efficiently captures fine particulates while optimizing flow rates for viscous organic samples
• Very low extractables minimize chromatographic interference and background contamination in analytical procedures
• Alcohol pre-wetting capability enables aqueous solution compatibility when required for ion chromatography applications
• Suitable for the clarification of organic solvents and for air venting processes with moisture barrier protection

Key Construction Characteristics

• Compact 4mm diameter format maximizes laboratory bench space while providing reliable filtration performance
• Luer-Lok® and pressure fitting connections deliver leak-tight syringe attachment for secure sample processing
• Ultrasonic bonding construction ensures reliable seal integrity during high-pressure filtration applications
• Polypropylene housing delivers chemical compatibility with harsh analytical solvents and reagents
• Clearly inscribed filter media identification prevents cross-contamination and ensures proper filter selection

LE-IWT-ES-10604 filters achieve exceptional unit-to-unit reproducibility optimized for HPLC sample preparation, accelerating your analytical cycles even with challenging organic matrices requiring solvent degassing. The unique concentric funnel-shaped barrel design increases filtration volume while decreasing back pressure, maximizing your laboratory efficiency when processing viscous chromatography samples. Outstanding chemical resistance to all solvents except hydrofluoric acid transforms these filters into versatile analytical tools, providing performance assurance for your critical gas chromatography, ion chromatography, and aerosol sampling applications demanding both chemical compatibility and validated filtration reliability.
