PES Syringe Filter, 0.45µm, 17mm, Nonsterile, Hydrophilic, Luer-Lock, 100/Pk SKU: LE-IWT-ES10311

Featuring hydrophilic polyethersulfone membrane technology delivering exceptional flow rates and minimal protein binding for critical sample preparation applications. High porosity asymmetric pore structure with 0.45µm retention provides reliable clarification while maintaining sample integrity throughout analytical workflows. Low protein and drug binding characteristics make it ideally suited for use in life sciences applications, optimizing recovery rates for protein solutions, tissue culture media, and pharmaceutical preparations.

Key PES Membrane Characteristics

• Hydrophilic polyethersulfone construction eliminates wetting issues and accelerates filtration of aqueous solutions
• Intrinsically low protein binding maximizes sample recovery for biological and pharmaceutical applications requiring quantitative results
• Exceptional compatibility with acids, bases, and oxidizer withstands aggressive chemical environments without membrane degradation
• Maximum recommended operating temperature of 60°C maintains structural integrity during elevated temperature processing
• Asymmetric pore structure delivers superior flow rates while providing consistent 0.45µm particle retention efficiency

Key Construction Characteristics

• Ultrasonic bonding technology creates leak-proof seal between housing and membrane for reliable performance under pressure
• Female Luer-Lock inlet with male Luer-Slip outlet provides secure syringe connection and universal downstream compatibility
• 17mm diameter membrane optimized for small volume filtration while maintaining adequate filtration area for efficient processing
• Medical-grade polypropylene housing delivers chemical resistance and dimensional stability throughout filtration cycles
• Color-coded barrel identification clearly indicates membrane type and pore size for error-free laboratory workflows

LE-IWT-ES10311 filters achieve outstanding unit-to-unit reproducibility ensuring consistent results across analytical batches, while their nonsterile format provides cost-effective processing for applications not requiring sterile conditions. These filters are especially appropriate for ion chromatography samples, tissue culture filtration, and the filtration of proteins, nucleic acids, and liquids subjected to high temperatures. Incorporating a syringe filtration step prior to chromatographic injection is essential for achieving more reliable and consistent results, while also protecting delicate instruments and prolonging the lifespan of columns, transforming your sample preparation into a validated and efficient process for HPLC, GC, and other analytical methodologies.
