Nylon Syringe Filter w/ Glass Fiber Prefilter, 0.45µm, 13mm, Nonsterile, 100/Pk SKU: LE-IWT-ES10233

Featuring hydrophilic nylon membrane technology with integrated glass fiber prefiltration delivering superior particle retention and extended service life for analytical applications. The 0.45 µm pore size provides optimal filtration for water-based and organic sample preparation while maintaining excellent flow characteristics and minimal extractable levels ideal for HPLC analysis. The graduated glass fiber prefilter eliminates larger particles and reduces membrane loading, significantly extending filter throughput capacity for particle-laden solutions requiring reliable clarification before chromatographic analysis.

Key Nylon Membrane Characteristics

Hydrophilic polyamide construction optimized for aqueous liquids and solvents with pH range 3-14 ensuring broad analytical compatibility
Ultra-low extractable levels deliver contamination-free sample preparation critical for HPLC and GC analytical protocols
Exceptional flow characteristics combined with high protein binding capacity and dirt loading capacity maximize filtration efficiency
Superior mechanical stability maintains structural integrity under analytical pressures while meeting stringent laboratory requirements
Natural hydrophilic properties enable immediate wetting without pre-conditioning for aqueous and polar organic solvents

Key Construction Characteristics

Binder-free glass fiber prefilter construction prevents contamination while providing coarse particle screening before final membrane filtration
Luer-Lock and pressure fitting compatibility ensures secure connections with standard laboratory syringes and automated systems
Low-extractable polyethylene housing construction minimizes sample contamination during analytical processing
Ultrasonically bonded assembly with clearly inscribed membrane identification enhances reliability and traceability
Concentric funnel-shaped barrel design increases sample volume capacity while reducing back pressure for efficient filtration

These filters deliver significantly higher throughput compared to standard filters when processing particle-rich solutions, making them ideal for dissolution testing, environmental analysis, and routine HPLC sample preparation. The nylon membrane excels with near-neutral pH aqueous solutions and compatible nonaqueous solvents, while the 13mm diameter provides optimal filtration area for small-volume analytical samples. Excellent unit-to-unit and lot-to-lot reproducibility ensures consistent analytical results across extended sampling campaigns, delivering the performance reliability essential for critical laboratory applications requiring both particulate removal and analytical accuracy.
