Nylon Syringe Filter w/ Glass Fiber Prefilter, Sterile, 0.45µm, 13mm, Hydrophilic, 100/Pk SKU: LE-IWT-ES10238

Featuring hydrophilic nylon membrane technology with integrated glass microfiber prefilter delivering superior particle retention and extended throughput for demanding analytical applications. This dual-stage filtration system combines a graduated glass fiber prefilter designed to eliminate larger particles with a 0.45µm membrane filter for fine filtration, extending service life by reducing particle loading on the final membrane. Maximum operating temperature of 60°C with sterile gamma-irradiated construction ensures reliable performance across diverse laboratory protocols requiring validated contamination control.

Key Nylon Membrane Characteristics

• Hydrophilic nylon construction delivers excellent compatibility with aqueous solutions and organic solvents while maintaining low extractable levels ideal for HPLC and GC analysis
• Exceptional flow characteristics combined with robust mechanical stability meets stringent analytical requirements
• pH compatibility range of 3-14 makes it particularly suitable for high-pH samples while avoiding protein recovery applications due to inherent protein binding
• Notable protein-binding capability and contaminant retention characteristics enhance sample clarification
• Individual sterile blister packaging with Luer-Lok® and pressure fitting compatibility ensures contamination-free handling

Key Construction Characteristics

• Glass fiber prefilter delivers significantly higher throughput compared to standard filters, particularly beneficial for solutions rich in suspended particles
• Leachable-free glass fiber prefilter construction combined with fastest flow polyamide membranes minimizes non-specific binding
• 13mm diameter configuration optimizes sample volume capacity while maintaining compact footprint for routine laboratory use
• Construction suitable for both manual syringe operation and automated sampling systems
• Polypropylene housing provides compatibility with harsh solvents, acids, and bases

LE-IWT-ES10238 filters achieve outstanding analytical performance through ultrasonically bonded construction ensuring unit-to-unit and lot-to-lot reproducibility critical for validated analytical methods. Optimized for water-based and organic sample preparation suitable for HPLC, GC, and dissolution analysis, these sterile filters transform your sample preparation workflow with their unique concentric funnel-shaped barrel design that increases volume capacity while decreasing back pressure. Enhanced particle loading capacity extends operational life even when processing challenging samples, maximizing your analytical efficiency while maintaining the sterility assurance essential for pharmaceutical and biotechnology applications.
