PES Syringe Filter, Hydrophilic, 0.45µm, 30mm, Luer-Lock, Nonsterile, 100/Pk SKU: LE-IWT-ES10313

Featuring hydrophilic polyethersulfone membrane technology delivering exceptional flow rates and minimal protein binding for analytical sample preparation. Low protein and drug binding characteristics make it ideally suited for use in life sciences applications, while PES (Polyethersulfone) delivers low affinity for proteins and extractables with substantially faster flow rates. The 0.45µm pore size provides reliable clarification removing general particulates and most bacteria while optimizing sample recovery for tissue culture, HPLC, and ion chromatography applications.

• Hydrophilic polyethersulfone construction maximizes wetting for aqueous solutions and biological samples
• Minimal protein adsorption preserves valuable proteins during filtration of culture media and buffer solutions
• Low extractables profile certified for ion chromatography maintains analytical integrity and reduces interference
• 0.45µm retention efficiency removes particulates while maintaining high flow rates for rapid processing
• Chemical compatibility with pH 3-12 solutions accommodates diverse analytical and biological applications

• 30mm diameter with optimized membrane area delivers enhanced throughput for large sample volumes
• Ultrasonically bonded housing construction prevents bypass and ensures reliable filtration integrity
• Standard Luer-Lock fitting provides universal syringe compatibility with no compatibility issues
• Concentric funnel-shaped barrel design increases working volume while decreasing back pressure during filtration
• FDA compliant polypropylene housing meets Title 21 CFR sections 177.1520 and 177.2600¹ for repeated contact applications

LE-IWT-ES10313 filters achieve consistent unit-to-unit reproducibility essential for quantitative analysis, accelerating your sample preparation workflows for bacteriophage filtration, tissue culture additives, and hybridization solution processing. Outstanding chemical resistance to common laboratory solvents maximizes your analytical flexibility when processing food, beverage, and ultra-pure water samples requiring validated performance. USP <87> and USP <88> compliance² validates cytotoxicity safety, providing performance assurance for your critical life sciences applications demanding both rapid throughput and pharmaceutical-grade purity standards.
