PTFE Syringe Filter, Hydrophobic, 0.22µm, 30mm, Luer-Lok Connection, Nonsterile, 100/Pk SKU: LE-IWT-ES10322

Featuring hydrophobic PTFE membrane technology providing exceptional chemical resistance and precision filtration for organic solvents, aggressive chemicals, and high-temperature applications. The 0.22µm pore configuration delivers reliable particle retention while maintaining superior flow characteristics through the 30mm diameter construction. Rugged polypropylene housing with Luer-Lok connection ensures leak-tight syringe compatibility and supports autoclave sterilization to 121°C for 15 minutes.

Key PTFE Membrane Characteristics

• Hydrophobic membrane with the highest chemical compatibility rating resists acids, bases, and aggressive organic solvents
• 0.22µm absolute pore rating provides precise particulate removal while optimizing flow rates for viscous samples
• Suitable for the filtration of aggressive organic substances, highly basic solutions, or hot liquids
• Capable of filtering aqueous solutions following pre-wetting with alcohol
• Eliminates interfering materials and fine particles down to the specified pore size, ensuring cleaner sample extracts

Key Construction Characteristics

• Luer lock inlet offers leak-tight syringe connection accommodating diverse laboratory equipment configurations
• 30mm diameter construction maximizes filtration area while maintaining compact profile for routine sample processing
• Glass microfiber prefilter extends membrane life by capturing larger particles before reaching primary filtration medium
• Ultrasonically bonded housing eliminates leakage points and delivers consistent unit-to-unit performance
• Color-coded membrane identification inscribed directly on barrel prevents cross-contamination and ensures proper selection

LE-IWT-ES10322 filters find applications in HPLC, organic solvent sample preparation and cleanup, dissolution sample analysis, general sample preparation, and for samples subjected to high temperatures or in caustic or acidic environments. The concentric funnel-shaped barrel design increases volume capacity while decreasing back pressure, accelerating your chromatography sample preparation workflows. Suitable for the clarification of organic solvents and for air venting processes, these filters deliver reliable performance for aerosol sampling, vacuum pump line protection, and moisture barrier applications requiring validated chemical resistance and dimensional stability.
