Cellulose Acetate (CA) Syringe Filters - SF18165

Medium-volume biological samples containing high particulate loads, such as those from cell culture supernatants, tissue homogenates, and environmental matrices, often clog filtration membranes prematurely, increasing processing time and reducing analytical throughput. Integrating glass fiber prefilters eliminates premature clogging. Combined with 0.45µm cellulose acetate membrane, 4.08cm² filtration area, and 100µL holdup volume, this system delivers efficient clarification performance.

Key Cellulose Acetate Membrane Characteristics

0.45µm pore size provides effective clarification for biological samples, removing particulates and cellular debris while maintaining solution clarity
Hydrophilic cellulose acetate construction enables rapid aqueous sample wetting without preparation steps, accelerating workflow efficiency
Preserves proteins and biomolecules with low binding affinity throughout filtration, maintaining concentration accuracy for quantitative applications
Resists aqueous biological matrices and buffer solutions while requiring protection from aggressive organic solvents
80-170µm membrane thickness delivers mechanical stability and consistent filtration performance across diverse sample types

Key Construction Characteristics

100µL holdup volume preserves samples in medium-volume applications where processing efficiency impacts laboratory productivity
Polypropylene housing rated to 87psi burst pressure and 60°C maximum temperature withstands routine laboratory conditions
Luer-Lok inlet combined with Luer Slip outlet enables secure syringe attachment and efficient sample recovery
4.08cm² filtration area with glass fiber prefilter captures high particulate loads before membrane contact, reducing clogging and extending filter life

Built to support your medium-volume clarification requirements where particulate loads challenge membrane performance, glass fiber prefilter technology extends operational life. Validated 23.2psi bubble point combined with low protein binding membrane construction ensures reliable clarification without biomolecule loss throughout processing. Nonsterile construction with autoclave and gamma sterilization options provides your laboratory operations with economical yet dependable filtration for biological samples, environmental testing, and analytical applications where extended filter life and sample recovery drive productivity.
