CA Syringe Filters, 5.0um, 30mm, Luer-Lok/Luer Slip, Sterile, 100/Pk SKU: SF18290

Cellulose Acetate Syringe Filters, 5.0µm, 30mm, Sterile

Featuring a 5.0µm cellulose acetate membrane in a 30mm diameter configuration, these sterile syringe filters deliver efficient gross filtration for protecting sensitive downstream analytical equipment and processes. The integrated glass fiber prefilter extends service life dramatically. Combined with a 4.9cm² filtration area and 300ml flow capacity, this design handles viscous samples where rapid processing matters most.

Key Cellulose Acetate Membrane Characteristics

• Naturally Hydrophilic Surface: Water-based samples flow immediately without pre-wetting steps, streamlining your sample preparation workflow and eliminating methanol compatibility concerns.
• Low Protein Binding Affinity: Preserves protein concentrations in biological samples by minimizing adsorption losses, essential when working with precious samples where recovery matters.
• Excellent Aqueous Compatibility: Maintains stable performance across biological buffers, culture media, and pharmaceutical formulations without membrane degradation or leachables.
• Large Pore Structure Benefits: The 5.0µm pore size removes particulate contamination and protects chromatography columns while maintaining exceptional flow rates through challenging sample matrices.
• Temperature Sensitivity Considerations: Operates reliably up to 60°C for most aqueous applications, though organic solvent compatibility is limited compared to more chemically resistant membrane materials.

Key Construction Characteristics

• Minimal Sample Loss: A 120µL holdup volume maximizes sample recovery in your large-volume applications, preserving costly reagents and valuable specimens.
• Dual Prefilter Protection: Integrated glass fiber prefilter captures high dirt loads before they reach the membrane surface, preventing premature clogging when your samples carry heavy particulate burdens.
• Durable Polypropylene Housing: Withstands operating pressures up to 87psi and temperatures to 60°C, providing mechanical strength for manual syringe pressure or vacuum manifold configurations.
• Universal Connection Compatibility: Luer-Lok and Luer Slip fittings adapt to standard laboratory syringes and tubing systems, integrating seamlessly into existing sample preparation protocols.

When your laboratory processes large sample volumes with significant particulate loads, you need filtration capacity that doesn't force repeated filter changes mid-batch. The 30mm diameter platform delivers 4.9cm² of active filtration area with glass fiber prefilter reinforcement, processing up to 110ml throughput per device. This combination maintains consistent flow rates and reliable particle removal across your most demanding sample preparation workflows, giving you the processing capacity to complete batch runs without interruption.

• HPLC Mobile Phase Prefiltration - Removes particulates from solvents before they reach expensive pump seals and column frits, extending instrument service intervals.
• Cell Culture Media Clarification - Eliminates cellular debris and aggregates from conditioned media while preserving secreted proteins for downstream analysis applications.
• Analytical Sample Preparation - Protects LC-MS ion sources and HPLC columns from particulate fouling in complex biological matrices and environmental samples.
• Aqueous Buffer Filtration - Clarifies phosphate buffers, Tris solutions, and electrophoresis reagents without chemical interaction, maintaining pH stability throughout processing.
• Viscous Sample Processing - Handles thick solutions and emulsions that would clog finer membranes, keeping your workflow moving when sample complexity challenges traditional filters.
• Prefiltration Protection - Protects sterile membranes and analytical equipment from gross contamination, extending downstream 0.22µm filter life.
