PES Membrane Syringe Filter, Nonsterile - 0.45µm, 4mm, Hydrophilic, 200/Pk SKU: LE-IWT-ES-10610

Featuring hydrophilic polyethersulfone membrane technology delivering exceptional flow rates and minimal protein binding for aqueous solution filtration. These hydrophilic filters constructed from pure polyethersulfone polymer membrane achieve maximum sample recovery with low protein and drug binding characteristics, making them ideally suited for life sciences applications. Advanced ultrasonic bonding construction ensures reliable performance with clearly inscribed membrane identification for consistent processing protocols.

Key PES Membrane Characteristics

• Hydrophilic polyethersulfone construction provides maximum sample recovery while maintaining chemical compatibility across wide pH ranges
• Low protein binding characteristics make these filters ideal for acids and bases filtration where sample integrity is critical
• 0.45µm pore size delivers reliable clarification of bacteriophage, hybridization solutions, and tissue culture media
• Asymmetric membrane structure maximizes flow rates while reducing back pressure for high-throughput applications
• Maximum operating temperature of 60°C accommodates heated sample processing and sterilization protocols

Key Construction Characteristics

• Medical-grade polypropylene housing with Luer-Lok® inlet and pressure fitting outlet ensures leak-tight syringe connections
• Ultrasonic bonding technology eliminates adhesives and provides superior membrane-to-housing integrity under pressure
• Compact 4mm diameter design optimizes sample volume while minimizing hold-up volume for precious samples
• Concentric funnel-shaped barrel increases filtration volume capacity and decreases back pressure during operation
• Low extractables composition prevents sample contamination and interference in chromatographic analysis

These filters achieve excellent unit-to-unit and lot-to-lot reproducibility, accelerating your analytical workflows while maintaining consistent results. Ion chromatography certification validates performance for trace analysis applications, while broad chemical compatibility with food, beverages, and ultra-pure water ensures versatility across laboratory environments. The nonsterile configuration provides cost-effective filtration for routine sample preparation, hybridization probe filtering, and final filtration applications where sterility is not required.
