CA Syringe Filters, 0.8 um, 30mm, Luer-Lok/Luer Slip, 100/Pk SKU: SF18287

Cellulose Acetate (CA) Syringe Filters - SF18287

Featuring a 0.8µm cellulose acetate membrane with a validated 11.6psi bubble point and polypropylene prefilter integration for large-volume samples containing suspended particles, this syringe filter removes aggregates before they reach sensitive analytical instruments. Rapid 150ml flow rates mean you process samples faster. Hydrophilic design with 4.9cm² filtration area and 120µL holdup volume supports prefiltration applications where protecting downstream equipment matters most.

Key Cellulose Acetate Membrane Characteristics

• 0.8µm pore size provides effective coarse prefiltration for biological samples, removing large particulates and aggregates before downstream processing
• Hydrophilic cellulose acetate construction enables immediate aqueous sample processing without pre-wetting requirements, accelerating workflow efficiency
• Minimizes adsorption of proteins and biomolecules throughout filtration, maintaining concentration accuracy for quantitative downstream applications
• Maintains compatibility with aqueous biological solutions and buffer systems while requiring protection from aggressive organic solvents
• 80-170µm membrane thickness balances mechanical durability with rapid flow characteristics for efficient large-volume prefiltration applications

Key Construction Characteristics

• 120µL holdup volume preserves samples in large-volume applications where recovery efficiency impacts analytical productivity
• Polypropylene housing withstands operating pressures to 87psi and temperatures to 60°C, accommodating diverse laboratory processing requirements
• Luer-Lok inlet combined with Luer Slip outlet ensures secure syringe attachment and facilitates convenient sample recovery
• 4.9cm² filtration area with integrated polypropylene prefilter captures high particulate loads, delivering 150ml flow rates for rapid processing

Built to support your large-volume prefiltration needs where particulate removal and rapid flow rates are essential, cellulose acetate technology delivers dependable processing. Validated 11.6psi bubble point combined with polypropylene prefilter construction ensures you get efficient coarse particle removal without compromising flow rates.
