Membrane Filter, CA, 0.22 um, 110mm, Nonsterile, 50 Pk SKU: SF18159

Cellulose Acetate (CA) Membrane Filters, 0.22µm, 110mm - SF18159

For critical applications requiring absolute sterility assurance, the Cellulose Acetate (CA) Membrane Filters series provides a verified barrier against bacterial contamination. To achieve this medical-grade standard, the filter utilizes a Cellulose Acetate (CA) membrane that provides a sharp 0.22 cutoff necessary for sterilizing biological fluids. Manufactured with strict thickness tolerances, these membranes provide a reliable barrier for critical filtration steps without compromising flow. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.

Key Cellulose Acetate (CA) Membrane Characteristics

• Cellulose Acetate (CA) membrane with hydrophilic affinity
• Moderate Binding characteristics
• Compatible with general aqueous solutions and weak organic solvents
• Sensitive to strong acids, alkalis, and oxidizing agents
• 0.22 rating suitable for sterile filtration

By selecting a filter that matches the exact chemical nature of your samples, you ensure that your workflow remains uninterrupted by membrane failures. You can rely on the certified integrity of these units to protect your critical samples and instrumentation from damaging contaminants. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
