Thumbnail Filmstrip of CA Syringe Filter, 0.45um, 33mm, Luer-Lok/Luer Slip, Nonsterile, 100/Pk Images
Cellulose Acetate (CA) Syringe Filters - SF14490
Featuring economical 0.45µm cellulose acetate membrane technology with integrated glass fiber prefiltration, these filters combine high-capacity 33mm platform design and 4.6cm² filtration area for efficient clarification of large-volume particulate-laden samples requiring sustained throughput. Hydrophilic construction enables immediate aqueous processing without pre-wetting delays. Superior 74ml flow rate with validated 23.2psi bubble point supports rapid processing of biological and pharmaceutical samples where particulate removal maintains analytical precision in high-volume workflows demanding cost-effective clarification with optimized 110µL holdup for sample preservation across demanding operations.
Key Cellulose Acetate Membrane Characteristics
- High-volume 0.45µm clarification efficiently removes particulates from large aqueous sample batches while maintaining rapid 74ml flow characteristics for demanding processing operations
- Hydrophilic membrane design provides immediate filtration capability without pre-wetting requirements, eliminating preparation steps and accelerating throughput efficiency in routine workflows
- Integrated glass fiber prefilter captures significant dirt-loads before reaching the cellulose acetate membrane, extending operational life and sustaining flow rates through dirty matrices
- Aqueous-optimized compatibility maintains stable operation with water-based biological fluids and buffers while incompatible with organic solvents, acids, and bases
- Autoclavable platform enables users to sterilize filters in-house at 121°C for 30 minutes, supporting customized preparation protocols and reducing operational costs
Key Construction Characteristics
- Enhanced 110µL holdup volume optimizes yield during high-volume processing where extended throughput capacity justifies moderate retention for operational efficiency
- Large 4.6cm² filtration area sustains exceptional 74ml flow rate performance at 87psi maximum operating pressure for high-capacity clarification applications
- Dual Luer-Lok/Luer Slip connectivity provides flexible interface options with standard laboratory syringes, eliminating adapter requirements and streamlining workflow integration
- Thermally stable housing operates reliably up to 60°C maximum temperature for ambient and moderately elevated processing conditions
When your high-volume clarification workflows demand exceptional throughput with extended dirt-load capacity, cellulose acetate prefiltration technology achieves workflow efficiency. Validated 23.2psi bubble point combined with glass fiber prefiltration ensures processing confidence throughout demanding applications. Autoclavable construction with optimized holdup volume supports your laboratory operations requiring economical yet reliable clarification performance across diverse large-volume aqueous sample matrices.
