Nylon Syringe Filter w/ Glass Fiber Prefilter, 0.22µm, 25mm, Nonsterile, 100/Pk SKU: LE-IWT-ES10234

Featuring hydrophilic polyamide membrane technology optimized for aqueous liquids and solvents with a pH of 3 - 14, these 0.22µm nylon syringe filters deliver exceptional particle retention for critical analytical applications. The integrated glass microfiber prefilter design maximizes loading capacity for highly particle-laden samples while maintaining fast flow rates essential for HPLC and GC sample preparation. Luer-Lok® connections with polypropylene housing construction provide secure attachment and broad chemical compatibility across aqueous and polar organic solvent systems.

Key Nylon Membrane Characteristics

Hydrophilic Nylon66 construction ideal for aqueous (non-acidic) or organic sample prep and HPLC, GC analysis
0.22µm absolute pore rating removes fine particles and contaminants while maintaining optimal flow characteristics
Excellent flow characteristics with very low extractable levels and mechanical stability for critical analytical procedures
Superior chemical compatibility compared to cellulose acetate, withstanding pH range 3-14 without membrane degradation
Exceptionally pure polyamide construction compared to standard nylon filters minimizes interference in LC-MS applications

Key Construction Characteristics

Glass fiber prefilter combines with polyamide membrane for fastest flow and low non-specific binding
Polypropylene housing delivers compatibility with harsh solvents, acids and bases
Ultrasonically bonded construction ensures reliable seal integrity and prevents media migration during filtration
25mm diameter provides optimal filtration area for sample volumes up to 100mL with enhanced throughput capacity
Luer-Lok® inlet and pressure fitting connections ensure secure attachment and prevent blowoff during operation

These filters achieve enhanced loading capacity through the integrated glass microfiber prefilter, extending operational life when processing turbid samples and complex biological matrices. The non-sterile design reduces waste and simplifies handling for sample preparation steps prior to HPLC or GC analysis. Outstanding protein binding characteristics make these filters ideal for clarifying biological samples while the broad pH tolerance maximizes application flexibility across alkaline dissolution testing and acidic extraction protocols.
