Cellulose Acetate (CA) Syringe Filters - SF18289

Pharmaceutical and biotechnology labs need large-volume coarse prefiltration that handles viscous samples and heavy particulate loads without sacrificing speed or clogging membranes mid-process. Advanced 1.2µm cellulose acetate membrane technology removes gross particulates while maintaining your sample integrity and those rapid 180ml flow rates. Glass fiber prefilter paired with 4.9cm² filtration area and 120µL holdup volume gives you efficient prefiltration that protects expensive downstream equipment.

Key Cellulose Acetate Membrane Characteristics

• 1.2µm pore size tackles coarse prefiltration efficiently, catching large particles and debris that would otherwise overwhelm your finer membranes later
• Hydrophilic cellulose acetate wets instantly with aqueous samples, meaning you start filtering immediately without pre-treatment steps eating into your time
• Low protein binding keeps your biomolecules in solution where you need them, preventing losses that throw off your downstream analysis
• Handles aqueous biological solutions and buffer systems reliably, though you'll want to avoid aggressive organic solvents that can damage the membrane
• 80-170µm membrane thickness strikes the balance between durability for large-volume work and maintaining those impressive flow rates you need

Key Construction Characteristics

• 120µL holdup volume maximizes what you recover from large-volume samples, minimizing losses when every milliliter impacts your productivity
• Polypropylene housing stands up to 87psi operating pressure and 60°C temperatures, giving you flexibility across different processing conditions
• Luer-Lok inlet locks your syringe securely while the Luer Slip outlet makes collecting your sample straightforward and efficient
• 4.9cm² filtration area working with glass fiber prefilter delivers exceptional 180ml flow rates, letting you process samples quickly without cutting corners on quality

When your large-volume samples carry viscous solutions and heavy particulate loads that challenge standard prefiltration, glass fiber prefilter technology handles the dirty work upfront. Validated 5.8psi bubble point ensures consistent coarse particle removal while delivering those rapid 180ml flow rates that keep your workflow moving. Nonsterile design with autoclave and gamma sterilization options supports your operations where economical yet reliable prefiltration protects expensive analytical equipment and maintains sample recovery, making the difference between meeting deadlines and falling behind schedule.

• Biological Sample Prefiltration - Removes large particles from cell lysates and tissue homogenates before final filtration, preventing membrane clogging
• Protein Solution Processing - Filters protein formulations with minimal adsorption while removing aggregates that interfere with purification processes
• Cell Culture Media Preparation - Clarifies viscous media components and supplements, removing particulates while preserving growth factors essential for viability
• Environmental Sample Clarification - Prepares ground water and surface water samples for subsequent analytical testing by removing suspended solids and debris
• Aqueous Buffer Filtration - Removes large particles from laboratory buffers and reagent solutions for chromatography applications requiring prefiltration
• HPLC Sample Preparation - Protects analytical columns from particulate blockage by prefiltering samples before final clarification and injection
