Cellulose Acetate (CA) Syringe Filters - SF14496

Biological samples and aqueous solutions often contain particulates that interfere with analytical measurements or cause instrumentation fouling during routine laboratory workflows. The SF14496 addresses challenge with a 0.45µm cellulose acetate membrane that clarifies samples while minimizing protein binding compared to other hydrophilic materials. Integrated glass fiber prefiltration extends service life when processing moderately particulate samples, protecting the primary membrane from premature fouling. The 33mm sterile configuration delivers 110mL throughput capacity for high-volume processing in pharmaceutical, biotechnology, and quality control laboratories.

Key Membrane Characteristics

• 0.45µm cellulose acetate membrane provides clarification with naturally hydrophilic surface chemistry for aqueous sample processing
• 4.6cm² filtration area in the 33mm diameter configuration enables large-scale sample preparation.
• Delivers 110mL volume throughput for high-volume clarification applications while maintaining low protein binding throughout processing
• 23.2psi bubble point ensures membrane integrity, while the 80-170µm thickness balances flow rate with mechanical strength
• Low protein-binding characteristics preserve biomolecule recovery during the filtration of proteins, enzymes, and biological extracts
• Integrated glass fiber prefilter captures coarse particles upstream to protect the primary membrane and extend operational life

Key Construction Characteristics

• Durable methacrylate butadiene styrene housing withstands operating pressures up to 87psi for demanding applications
• 110µL holdup volume balances the large membrane diameter with efficient sample recovery for your processing needs
• Dual luer-lok/luer slip inlet and outlet connections provide compatibility with standard syringes and automated dispensing systems
• Each filter arrives gamma-sterilized and individually packaged to maintain contamination-free conditions until use

Your clarification workflows gain efficiency from sterile-ready filters that eliminate preparation steps. The cellulose acetate membrane naturally resists protein adsorption while the glass fiber prefilter handles moderate particulate loads without compromising the primary membrane. The 33mm format processes larger sample volumes efficiently while maintaining the low protein binding that makes cellulose acetate ideal for biological solutions across pharmaceutical, biotechnology, and environmental testing applications.
