Cellulose Acetate (CA) Syringe Filters - SF14493

Precision 0.22µm cellulose acetate membrane technology with integrated polypropylene prefiltration delivers validated bacterial retention on a gamma-sterilized 25mm platform, featuring 4.08cm² filtration area optimized for medium-volume sterile processing applications. Hydrophilic characteristics enable immediate aqueous sample processing without pre-wetting delays. Validated 40.6psi bubble point combined with prefiltration design supports demanding pharmaceutical quality control, biological sample preparation, and analytical workflows requiring absolute contamination control with efficient 100µL holdup for sample preservation in ready-to-use medium-volume sterile operations.

Key Cellulose Acetate Membrane Characteristics

• Validated 0.22µm sterile-grade retention provides bacterial removal for pharmaceutical and biological applications where absolute contamination control throughout sample processing remains critical
• Gamma-sterilized ready-to-use platform eliminates preparation requirements and contamination risks associated with handling nonsterile filters before critical sterile processing operations
• Integrated polypropylene prefilter captures gross particulates upstream of the sterile membrane, extending operational life and maintaining flow rates through moderately dirty samples
• Hydrophilic membrane architecture enables immediate aqueous sample processing without pre-wetting steps, eliminating preparation delays and accelerating workflow efficiency
• Aqueous-optimized compatibility maintains stable operation with water-based biological fluids and pharmaceutical buffers across diverse medium-volume laboratory applications

Key Construction Characteristics

• Moderate 100µL holdup volume optimizes yield during 10-100ml processing where recovery efficiency impacts both analytical precision and operational economics
• Generous 4.08cm² filtration area enables sustained 32ml flow rate performance at 87psi maximum operating pressure for medium-volume sterile filtration applications
• Universal Luer-Lok/Luer Slip interface ensures compatibility with standard laboratory syringes, enabling rapid connections without specialized adapters or workflow interruptions
• Thermally stable polypropylene housing maintains reliable structural integrity up to 60°C maximum temperature for ambient and moderately elevated processing conditions

Engineered to overcome your medium-volume sterile processing challenges where particulate loading compromises standard filters, gamma-sterilized prefiltration technology delivers quality assurance. Validated 40.6psi bubble point combined with integrated prefiltration ensures bacterial retention confidence throughout demanding pharmaceutical workflows. Ready-to-use gamma-sterilized construction with optimized holdup volume supports your laboratory operations requiring dependable yet economical sterile filtration of moderately dirty medium-volume samples.
