CA Syringe Filter, 0.22 um, 4 mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF18201

Cellulose Acetate (CA) Syringe Filters - SF18201

Precision 0.22µm cellulose acetate membrane with validated 40.6psi bubble point integrity and gamma sterilization packaging delivers immediate bacterial retention capability for micro-volume biological samples requiring contamination-free processing throughout critical applications. Critical cell culture media sterilization and protein solution filtration benefit from ready-to-use membrane performance. Combined hydrophilic wetting characteristics with 1µL holdup volume and low protein binding properties ensure efficient sterile filtration without preparation delays.

Key Cellulose Acetate Membrane Characteristics

• 0.22µm pore size provides sterile-grade bacterial retention for cell culture media and sensitive biological preparations requiring microbiological control
• Hydrophilic cellulose acetate membrane enables immediate aqueous sample processing without pre-wetting steps, eliminating workflow delays
• Low protein binding affinity preserves biomolecules throughout filtration, maintaining accurate concentrations for downstream quantitative analysis
• Maintains compatibility with aqueous protein solutions and biological buffers while requiring protection from aggressive organic solvents
• 80-170µm membrane thickness provides mechanical durability and consistent filtration performance throughout micro-volume processing applications

Key Construction Characteristics

• 1µL holdup volume maximizes recovery in micro-volume applications where complete sample retrieval determines experimental success
• Polypropylene housing withstands operating pressures to 87psi and temperatures to 60°C, supporting diverse sample processing requirements
• Luer-Lok inlet combined with Luer Slip outlet ensures secure syringe attachment and facilitates convenient sample collection
• 0.125cm² filtration area with polypropylene prefilter removes large particulates before membrane contact, protecting bacterial retention capability

Engineered to overcome your micro-volume sterile filtration challenges where bacterial retention and sample recovery are critical, gamma-sterilized construction eliminates preparation time. Validated 40.6psi bubble point combined with low protein binding membrane construction delivers consistent bacterial removal without biomolecule losses throughout processing. Ready-to-use sterile design supports your laboratory operations requiring reliable bacterial retention for tissue culture media, protein solutions, and biological samples where contamination control and immediate availability determine analytical success.
