PES Syringe Filter, Hydrophilic, 0.22µm, 25mm, Luer-Lok, Nonsterile, 100/Pk SKU: LE-IWT-ES10066

Featuring high porosity asymmetric pore structure technology delivering optimal flow rates and exceptional sample recovery for analytical applications. The 0.22µm pore configuration combines with intrinsically low protein binding characteristics to maximize throughput while maintaining sample integrity during chromatographic and biological sample preparation. Hydrophilic polyethersulfone construction results in high throughputs when these small filter devices are used to sterilize or clarify viscous proteinaceous solutions.

Key PES Membrane Characteristics

• Hydrophilic membrane with high flow rate, low dissolution, and good strength delivers consistent performance across diverse sample types
• Does not adsorb proteins and extracts, and does not pollute the sample ensuring maximum sample recovery for critical analyses
• Exceptional compatibility with acids, bases, and oxidizer provides versatile processing capabilities across pH ranges 1-14
• Low resistance, fast filtration speed, low protein adsorption optimizes workflow efficiency in high-volume laboratory environments
• Fast and low protein adsorption characteristics maintain biological activity during sterile filtration processes

Key Construction Characteristics

• Ultrasonically bonded polypropylene housing with clearly inscribed filter media type ensures reliable leak-proof performance
• Female Luer-Lok® inlet with male Luer slip outlet provides secure, standardized connections compatible with all syringe systems
• 25mm diameter membrane delivers 4.08 cm² filtration area optimizing throughput for routine laboratory applications
• Concentric funnel-shaped barrel design increases sample volume capacity while decreasing back pressure during filtration
• Maximum recommended operating temperature of 60°C accommodates heated samples and mild thermal processing requirements

LE-IWT-ES10066 filters achieve excellent unit-to-unit and lot-to-lot reproducibility ensuring consistent analytical results across extended sampling campaigns. Outstanding chemical compatibility with aqueous solutions, mild organics, and biological samples accelerates your sample preparation workflows for HPLC, ion chromatography, and tissue culture applications. Especially suitable for the filtration of viscous biological and cell tissue samples, these filters transform routine sample prep into efficient, contamination-free processing while maintaining the integrity of proteins, buffers, and nucleic acids critical to your analytical success.
