Cellulose Acetate (CA) Syringe Filters - SF14491

Small-volume pharmaceutical workflows face persistent challenges maintaining validated bacterial retention while processing samples containing moderate particulate loading that rapidly fouls single-membrane filters, creating operational bottlenecks in sterile testing. Standard filters lack prefiltration capacity for dirty samples. Gamma-sterilized cellulose acetate membrane technology with integrated polypropylene prefiltration resolves these limitations through ready-to-use multi-stage design. Technical specifications include validated 40.6psi bubble point ensuring 0.22µm bacterial retention, compact 13mm platform with 1.09cm² filtration area, and minimal 20µL holdup supporting 8ml flow rate with 10ml throughput capacity for reliable small-volume sterile processing.

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 reduces 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 while incompatible with organic solvents, acids, and bases

Key Construction Characteristics

Minimal 20µL holdup volume preserves valuable samples during 1-10ml processing where every microliter directly impacts analytical precision and experimental outcomes
Compact 13mm platform provides space-efficient sterile filtration for small-volume applications with 8ml flow rate performance at 87psi maximum operating pressure
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

Built to support your small-volume sterile processing requirements where particulate loading compromises standard filters, gamma-sterilized prefiltration technology delivers operational excellence. Validated 40.6psi bubble point combined with prefiltration ensures bacterial retention confidence throughout pharmaceutical workflows. Ready-to-use gamma-sterilized construction with minimal holdup volume supports your laboratory operations requiring dependable yet economical sterile filtration of moderately dirty small-volume samples.
