Cellulose Acetate (CA) Syringe Filters - SF18274

Medium-volume biological samples with high particulate loads from environmental water matrices, cell culture supernatants, and tissue homogenates frequently cause premature membrane clogging, compromising analytical throughput and requiring multiple filter changes throughout processing workflows. Glass fiber prefilter technology eliminates premature clogging. Combined with gamma-sterilized 0.45µm cellulose acetate membrane, 4.08cm² filtration area, and 100µL holdup volume, ready-to-use construction delivers contamination-free clarification.

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 surface enables instant aqueous sample processing without pre-wetting steps, eliminating workflow preparation time
Low protein binding affinity preserves biomolecules throughout filtration, maintaining concentration accuracy for quantitative downstream analysis
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 across diverse medium-volume applications

Key Construction Characteristics

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

When your medium-volume samples contain high particulate loads that challenge membrane performance and require contamination-free processing, glass fiber prefilter technology extends filter life. Validated 23.2psi bubble point combined with low protein binding membrane construction ensures reliable clarification without biomolecule losses throughout processing. Ready-to-use sterile construction supports your laboratory operations requiring economical yet dependable filtration for biological samples, environmental testing, and pharmaceutical applications where extended operational life and immediate availability drive productivity.
