Nylon Syringe Filter, Nonsterile - 0.45µm, 25mm Hydrophilic, HPLC/GC Sample Prep, 100/pk SKU: LE-IWT-ES10003

Featuring hydrophilic nylon membrane technology delivering reliable filtration performance for analytical sample preparation and chromatography applications. The 0.45µm pore size provides precise particulate removal while maintaining exceptional flow characteristics for aqueous and polar organic solutions. Ultrasonically bonded construction with clearly inscribed membrane identification ensures consistent unit-to-unit reproducibility and enhanced laboratory workflow efficiency.

Key Nylon Membrane Characteristics

Hydrophilic nylon construction optimizes wetting and filtration of aqueous and polar organic solutions
Low extractable levels¹ minimize interference with analytical results during HPLC and GC sample preparation
High mechanical strength and stable chemical properties deliver reliable performance across diverse solvents
Excellent chemical resistance to bases, alcohols, and most organic-aqueous mixtures maximizes versatility
Superior dirt-loading capacity extends filter life during high-particulate sample processing

Key Construction Characteristics

Concentric funnel-shaped barrel design increases effective volume while decreasing back pressure for enhanced flow
25mm diameter provides optimal filtration area for sample volumes up to 100mL with minimal hold-up volume
Luer-Lok™ fitting ensures secure syringe connection and prevents leakage during high-pressure applications
Ultrasonically bonded polypropylene housing delivers chemical resistance and structural integrity
Nonsterile design enables cost-effective filtration for routine analytical applications not requiring sterility

LE-IWT-ES10003 filters achieve maximum operating temperatures up to 60°C while maintaining dimensional stability and flow characteristics throughout extended use cycles. Exceptional compatibility with high pH samples and polar solvents accelerates your sample preparation workflows across dissolution testing, environmental analysis, and pharmaceutical research applications. Note that protein binding characteristics make these filters unsuitable for protein recovery applications, while their resistance to acids, halogenated solvents, and aggressive chemicals ensures reliable performance when processing complex analytical matrices requiring validated chromatographic results.

¹ Low extractable levels are critical for HPLC sample preparation to avoid analytical interference and maintain data integrity in chromatographic analysis.
