Cellulose Acetate (CA) Syringe Filters - SF18285

Pharmaceutical and biotechnology laboratories require large-volume sterile filtration solutions for cell culture media, protein formulations, and biological samples where bacterial retention combined with low protein binding characteristics preserve sample integrity throughout critical processing workflows. Cellulose acetate membrane technology delivers reliable bacterial removal. Hydrophilic design with 4.9cm² filtration area, polypropylene prefilter integration, and 120µL holdup volume enables efficient bacterial retention for large-volume biological samples.

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 membrane enables immediate aqueous sample compatibility without pre-wetting requirements, accelerating workflow efficiency
• Preserves proteins and biomolecules with low binding affinity throughout filtration, maintaining concentration accuracy for quantitative downstream applications
• Maintains compatibility with aqueous biological solutions and buffer systems while requiring protection from aggressive organic solvents
• 80-170µm membrane thickness delivers mechanical durability and consistent filtration performance throughout large-volume processing applications

Key Construction Characteristics

• 120µL holdup volume optimizes yield in large-volume applications where sample recovery directly impacts analytical productivity
• Polypropylene housing withstands operating pressures to 87psi and temperatures to 60°C, supporting diverse laboratory processing conditions
• Luer-Lok inlet combined with Luer Slip outlet provides secure syringe attachment and facilitates efficient sample recovery
• 4.9cm² filtration area with polypropylene prefilter delivers 40ml flow rates while removing large particulates before bacterial retention

When your large-volume samples require sterile-grade bacterial retention and low protein binding for sensitive biological applications, cellulose acetate technology delivers reliable processing. Validated 40.6psi bubble point combined with polypropylene prefilter construction ensures consistent bacterial removal without biomolecule losses throughout processing. Nonsterile design with autoclave and gamma sterilization options supports your laboratory operations requiring economical yet dependable bacterial retention for tissue culture media, protein solutions, and biological samples where sample integrity and processing efficiency drive analytical success.
