CA Syringe Filter, 0.22 um, 33mm, Double Luer Lock, Sterile, 100/Pk SKU: SF18283

Cellulose Acetate (CA) Syringe Filters - SF18283

Featuring 0.22µm cellulose acetate membrane with 40.6psi bubble point validation, gamma sterilization packaging, 5cm² filtration area, and modified butadiene styrene housing for high-volume biological samples requiring contamination-free bacterial retention without preparation delays. Ready-to-use sterile construction eliminates preparation time and workflow interruptions. Double Luer Lock connection combined with 200µL holdup volume and low protein binding ensures secure processing for tissue culture media and protein solutions demanding immediate sterile filtration capability.

Key Cellulose Acetate Membrane Characteristics

• 0.22µm pore size provides sterile-grade bacterial retention for cell culture media and biological preparations requiring microbiological control
• Hydrophilic cellulose acetate surface enables instant aqueous sample processing without pre-wetting steps, streamlining high-volume workflows
• Low protein binding characteristics preserve biomolecule concentrations throughout filtration, maintaining sample integrity for downstream quantitative analysis
• Maintains compatibility with aqueous biological solutions and buffer systems while requiring protection from aggressive organic solvents
• 80-170µm membrane thickness provides mechanical durability and consistent filtration performance throughout high-volume sterile processing applications

Key Construction Characteristics

• 200µL holdup volume minimizes loss in high-volume applications where sample recovery directly impacts laboratory productivity
• Modified butadiene styrene housing withstands operating pressures to 87psi and temperatures to 60°C, supporting diverse processing conditions
• Double Luer Lock connection system ensures secure syringe attachment on both inlet and outlet, preventing leaks throughout processing
• 5cm² filtration area with polypropylene prefilter delivers 40ml flow rates while removing large particulates before bacterial retention

When your high-volume samples require sterile-grade bacterial retention without preparation delays or contamination risks, gamma-sterilized construction delivers immediate processing capability. Validated 40.6psi bubble point combined with low protein binding membrane construction ensures 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 processing efficiency and immediate availability determine analytical success.
