Cellulose Acetate Syringe Filter, Sterile, 0.45µm, 13mm, Hydrophilic CA Membrane, 100/Pk SKU: LE-IWT-ES10089

Featuring sterile cellulose acetate membrane technology delivering exceptional protein recovery for critical biological sample preparation applications. These hydrophilic, pure cellulose acetate membranes are our lowest protein binding filters available. They are ideally suited for filtrations requiring maximum protein recovery, especially biological and clinical analyses. The 0.45µm pore size provides precise particulate retention while cellulose acetate (CA), should be considered to ensure maximum recovery for protein-containing solutions. Individual sterile packaging with ultrasonically welded construction ensures contamination-free processing for your most demanding analytical protocols.

Key Cellulose Acetate Membrane Characteristics

• Ultra-low protein binding capacity maximizes sample recovery in biological fluid processing and protein analysis applications
• Capillary action associated with surface tension forces causes the water to spontaneously enter and fill the pores. In this manner, the membranes are easily wetted and allow the bulk flow of water through the pores.
• Pure cellulose acetate polymer construction eliminates interference from organic binders or additives during trace analysis
• Surfactant-treated membrane surface ensures consistent wettability and reliable flow characteristics across sample types
• Absolute 0.45µm pore rating delivers validated particulate retention for sterile filtration and clarification protocols

Key Construction Characteristics

• Individual sterile packaging maintains aseptic conditions with controlled exposure to gamma irradiation. The amount of irradiation is carefully controlled to ensure a sufficient dose for sterility. The effectiveness of the treatment is monitored for each lot by using strategically placed spore strips and sterility is confirmed before a lot is released for sale.
• Ultrasonically bonded construction provides leak-free operation and eliminates potential bypass around membrane edges
• Female Luer-Lok® inlet and male slip outlet connections accommodate standard syringe configurations and pressure fittings
• 13mm membrane diameter optimized for small sample volumes while maintaining efficient processing speeds
• Concentric funnel-shaped barrel design increases sample volume capacity and reduces backpressure during filtration cycles

LE-IWT-ES10089 filters achieve outstanding unit-to-unit reproducibility, accelerating your sample preparation workflows for HPLC analysis, serum processing, and biological fluid sterilization. These filters are particularly well-suited for biological sample preparation, as they effectively filter enzymes and proteins while retaining very low levels of protein. They are also ideal for the filtration of protein-containing solutions, minimizing protein loss. Additionally, these filters are utilized in receptor binding studies and are suitable for both tissue culture media sterilization and the removal of cellular constituents from solutions. Nitrate-free cellulose acetate construction delivers validated performance for groundwater analysis and environmental monitoring applications requiring maximum analytical precision and sterile sample handling.
