Nylon Syringe Filter w/ Glass Prefilter, 0.45µm, 25mm, Hydrophilic HPLC/GC, 100/Pk SKU: LE-IWT-ES10235

Featuring hydrophilic nylon membrane technology with integrated glass microfiber prefilter delivering enhanced sample preparation for HPLC and GC analysis applications. Low inherent levels of extractables optimize sample integrity for chromatographic analysis, while the dual-layer filtration system maximizes dirt-loading capacity and extends filter life for challenging samples. Ideal performance with near neutral pH aqueous solutions and compatible nonaqueous solvents ensures versatility across diverse analytical protocols requiring 0.45µm particulate retention.

Key Nylon Membrane Characteristics

Hydrophilic surface chemistry provides instant wetting without priming, accelerating sample processing workflows
High mechanical strength construction withstands processing pressures while maintaining consistent pore structure integrity
High flow rate characteristics enable fast filtration while maintaining excellent particle retention performance
Chemical compatibility with aqueous solutions, alcohols, esters, and organic solvents maximizes analytical flexibility
Protein binding properties make these filters unsuitable for protein recovery but ideal for sample clarification applications

Key Construction Characteristics

Glass microfiber prefilter increases absorption capacity and extends operational life for high-particulate samples
25mm diameter configuration delivers optimal filtration area for standard laboratory sample volumes
Luer-Lock connection system ensures secure syringe attachment and prevents sample loss during filtration
Ultrasonically bonded housing construction eliminates adhesive contamination and ensures reliable seal integrity
Filter media type clearly inscribed on barrel enables quick identification and prevents cross-contamination

LE-IWT-ES10235 filters achieve exceptional unit-to-unit reproducibility optimized for dissolution sample analysis and routine HPLC sample preparation, maximizing your analytical consistency across extended measurement campaigns. Outstanding chemical stability with high pH samples transforms these filters into reliable workhorses for alkaline sample processing, while the integrated prefilter system delivers superior dirt-loading performance for samples containing suspended particulates. The concentric funnel-shaped barrel design reduces back pressure while increasing sample volume capacity, providing enhanced efficiency for your critical chromatographic sample preparation and general laboratory filtration applications demanding both reliability and cost-effectiveness.
