PTFE Syringe Filter, Hydrophobic, 0.45µm, 30mm, Glass Microfiber Prefilter, 100/Pk SKU: LE-IWT-ES10323

Featuring hydrophobic PTFE membrane technology with integrated glass microfiber prefilter delivering superior particulate retention for demanding analytical applications. The 0.45µm pore rating provides exceptional chemical resistance across pH 1-14 range while maintaining optimal flow characteristics for viscous organic solvents and aggressive HPLC mobile phases. Ultrasonically welded polypropylene housing construction with Luer-Lok® inlet and pressure fitting connections ensures leak-proof performance during high-pressure filtration protocols.

Key PTFE Membrane Characteristics

• Hydrophobic polytetrafluoroethylene membrane delivers outstanding chemical compatibility with acids, bases, and organic solvents
• 0.45µm absolute pore rating provides reliable particulate removal while maximizing flow rates for analytical sample preparation
• Polypropylene support structure maintains membrane integrity during filtration of gas and organic solvent applications
• Glass microfiber prefilter extends membrane life by capturing larger particles before reaching primary filtration layer
• Low extractables design minimizes chromatographic interference for sensitive HPLC and GC analysis protocols

Key Construction Characteristics

• 30mm diameter housing accommodates higher volume processing while maintaining compact design for standard laboratory workflows
• Ultrasonically bonded construction eliminates adhesive contamination and ensures consistent unit-to-unit reproducibility
• Concentric funnel-shaped barrel design increases filtration volume capacity while reducing back pressure during sample processing
• Female Luer-Lok inlet and male Luer slip outlet connections provide secure, leak-resistant attachment to syringes and equipment
• Clearly inscribed membrane type identification on barrel prevents cross-contamination and ensures proper filter selection

LE-IWT-ES10323 filters achieve exceptional performance in chromatography solvent degassing, viscous organic-based sample preparation, and aerosol sampling applications requiring absolute chemical resistance. Outstanding compatibility with common HPLC solvents and certified low extractables profile maximizes analytical accuracy for pharmaceutical research, environmental monitoring, and quality control protocols. After pre-wetting with alcohol, these versatile filters adapt to aqueous applications including ion chromatography sample preparation, delivering the analytical flexibility your laboratory demands for both routine and specialized filtration requirements.
