Cellulose Acetate (CA) Syringe Filters - SF18288

Processing large sample volumes with heavy particulate loads means you're constantly fighting clogged membranes, wasting time on filter changes when you need results fast. Glass fiber prefilter technology tackles this head-on by capturing debris before it reaches your membrane. Gamma-sterilized 0.8µm cellulose acetate membrane paired with 4.9cm² filtration area gives you contamination-free coarse prefiltration that keeps your workflow moving.

Key Cellulose Acetate Membrane Characteristics

• 0.8µm pore size handles coarse prefiltration work efficiently, catching large particulates and aggregates that would otherwise clog your finer membranes downstream
• Hydrophilic cellulose acetate wets instantly when aqueous samples hit it, so you skip the pre-treatment hassle and get straight to filtering
• Low protein binding keeps your valuable biomolecules in solution instead of stuck to the membrane, maintaining concentrations you can count on
• Works reliably with aqueous biological solutions and buffer systems, though you'll want to steer clear of aggressive organic solvents
• 80-170µm membrane thickness gives you the durability you need for large-volume work without sacrificing those rapid flow rates

Key Construction Characteristics

• 120µL holdup volume means you're recovering more of your sample in large-volume applications where losing even small amounts hurts productivity
• Polypropylene housing stands up to 87psi operating pressure and 60°C temperatures, handling whatever processing conditions you throw at it
• Luer-Lok inlet locks your syringe securely in place, while the Luer Slip outlet makes sample collection straightforward
• 4.9cm² filtration area working with glass fiber prefilter delivers impressive 150ml flow rates, letting you process samples quickly without cutting corners

When you're processing large sample volumes loaded with particulates that slow everything down and burn through expensive membranes, glass fiber prefilter technology extends your filter life significantly. Validated 11.6psi bubble point ensures consistent coarse particle removal while maintaining those rapid 150ml flow rates you need. Ready-to-use sterile construction means no prep time where contamination control matters, giving you reliable prefiltration for biological samples, pharmaceutical testing, and environmental work where speed and sample recovery determine whether you meet deadlines.
