Cellulose Acetate Syringe Filter, Sterile, 0.45µm, 25mm, Hydrophilic, Luer Lock, 100/Pk SKU: LE-IWT-ES10091

Featuring hydrophilic cellulose acetate membrane technology delivering exceptional protein recovery and minimal binding characteristics for critical biological sample processing. The 0.45µm pore configuration provides reliable particulate retention while maintaining optimal flow rates through sterile analytical workflows. Individual blister packaging with gamma sterilization ensures contamination-free processing for HPLC sample preparation, biological fluid clarification, and sterile media filtration applications requiring maximum sample recovery.

Key Cellulose Acetate Membrane Characteristics

• Hydrophilic cellulose acetate construction provides the lowest protein binding characteristics ensuring maximum recovery of biological molecules
• Surfactant-treated membrane surface ensures excellent wettability and consistent filtration performance across aqueous solutions
• Cellulose diacetate polymer with integral nonwoven polyester support layer delivers enhanced strength and handling ease
• 0.45µm absolute pore size rating captures particulates while allowing efficient processing of viscous proteinaceous samples
• Maximum operating temperature of 60°C maintains membrane integrity during heated sample processing applications

Key Construction Characteristics

• 25mm diameter format accommodates standard analytical volumes with optimized surface area for consistent flow rates
• Gamma irradiation sterilization with controlled dose monitoring ensures sterile processing without chemical residues
• Luer-Lock® inlet and pressure fitting connections provide secure attachment preventing sample loss during filtration
• Individual blister packaging maintains sterility while enabling single-use convenience in laboratory environments
• Ultrasonically bonded housing construction eliminates adhesives while clearly inscribed barrel markings identify membrane specifications

LE-IWT-ES10091 filters achieve excellent unit-to-unit reproducibility with concentric funnel-shaped barrel design reducing back pressure during high-volume processing. ISO 9001 compliant manufacturing¹ provides validated quality assurance for pharmaceutical and biotechnology applications demanding certified performance standards. Outstanding chemical compatibility with aqueous and protein-based HPLC solutions maximizes your analytical flexibility when processing groundwater samples, biological fluids, and sterile media requiring nitrate-free filtration media for EPA-compliant analytical protocols.
