Cellulose Acetate (CA) Syringe Filters - SF18284

Large-volume biological samples containing suspended particulates and cellular debris from cell culture supernatants, tissue homogenates, and environmental matrices challenge sterile filtration membranes, causing premature clogging and reducing processing throughput throughout contamination-sensitive workflows. Glass fiber prefilter technology eliminates premature clogging and extends operational life. Combined with gamma-sterilized 0.22µm cellulose acetate membrane, 4.9cm² filtration area, and 120µL holdup volume, ready-to-use construction delivers contamination-free bacterial retention.

Key Cellulose Acetate Membrane Characteristics

• 0.22µm pore size delivers sterile-grade bacterial retention for cell culture media and biological preparations requiring microbiological control
• Hydrophilic cellulose acetate construction provides instant aqueous sample processing without pre-wetting requirements, streamlining high-volume workflows
• Low protein binding affinity maintains biomolecule concentrations throughout filtration, preserving sample integrity for downstream quantitative applications
• Resists aqueous biological matrices and buffer solutions while requiring protection from aggressive organic solvents and harsh chemicals
• 80-170µm membrane thickness ensures mechanical robustness and consistent filtration performance throughout large-volume sterile processing applications

Key Construction Characteristics

• 120µL holdup volume preserves samples in large-volume applications where recovery efficiency impacts laboratory productivity
• Polypropylene housing withstands operating pressures to 87psi and temperatures to 60°C, accommodating diverse processing conditions
• Luer-Lok inlet with Luer Slip outlet provides secure syringe attachment and facilitates efficient sample recovery
• 4.9cm² filtration area with glass fiber prefilter delivers 40ml flow rates while capturing high particulate loads before bacterial retention

Engineered to overcome your large-volume sterile filtration challenges where particulate loads compromise membrane performance and contamination control is critical, glass fiber prefilter technology extends filter life. Validated 40.6psi bubble point combined with low protein binding membrane construction ensures bacterial removal without biomolecule losses throughout processing. Ready-to-use sterile construction supports your laboratory operations requiring reliable bacterial retention for tissue culture media, protein solutions, and biological samples where extended operational life and immediate availability drive productivity.
