PES Syringe Filter, Nonsterile, 0.22µm, 17mm, Hydrophilic Polyethersulfone, Luer-Lok, 100/Pk SKU: LE-IWT-ES10310

Featuring hydrophilic polyethersulfone membrane technology delivering intrinsically low protein binding for maximum sample recovery in critical analytical applications. High porosity asymmetric pore structure with 0.22µm retention provides reliable sterilization-grade filtration while maintaining exceptional flow rates through the 17mm membrane configuration. Exceptional compatibility with acids, bases, and oxidizer solutions ensures versatile performance across diverse laboratory protocols requiring contamination-free sample preparation.

Key Polyethersulfone Membrane Characteristics

• Highest flow rate performance with intrinsically low protein binding maximizes sample throughput and recovery efficiency
• pH stability range of 3-12 accommodates both acidic and basic sample matrices without membrane degradation
• Maximum operating temperature of 60°C enables processing of heated solutions and thermally sensitive compounds
• Hydrophilic membrane with high flow rate and low dissolution properties prevents sample contamination and adsorption losses
• 0.22µm pore size ideal for sterilization of tissue culture media and protein solutions ensuring validated sterile filtration performance

Key Construction Characteristics

• Medical-grade polypropylene housing with ultrasonic welding delivers high-pressure resistance and leak-free operation
• Luer-Lok connections provide secure, standardized attachment to syringes and sampling equipment without cross-threading risks
• Non-slip design with high-pressure resistance ensures safe handling during manual filtration procedures
• 17mm diameter configuration balances filtration area with compact design for efficient processing of small to medium sample volumes
• Ultrasonically bonded construction eliminates adhesive contamination while ensuring reliable membrane-to-housing integrity throughout operation

LE-IWT-ES10310 filters achieve superior chemical compatibility across organic solvents, aqueous solutions, and biological matrices, accelerating your sample preparation workflows for HPLC, ion chromatography, and protein analysis applications. Low resistance and fast filtration speed with minimal protein adsorption makes these filters especially suitable for processing viscous biological samples and cell culture media. Nonsterile format provides cost-effective performance for routine analytical applications where sterility validation is not required, delivering consistent filtration results with excellent unit-to-unit reproducibility for your critical laboratory protocols.
