CA Membrane Circle (OE 67), 0.45um Pore Size, 110mm Circle (50 pcs) SKU: 10404026

Cellulose Acetate (CA) Membrane Filters - 10404026

Precision-manufactured Hydrophilic membrane with a verified 0.45 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Built for consistent results, precision-manufactured Hydrophilic membrane with a verified 0.45 pore structure delivers consistent retention across the full operating range. Accordingly, each membrane disc reflects a manufacturing standard where retention characteristics, physical integrity, and dimensional accuracy are verified before release.

Material Specifications

• Distinguished by their very low protein binding, making them ideal for protein recovery.
• Economical bulk packaging supports laboratories with high consumable throughput where individual sterile wrapping is unnecessary.
• Particularly well suited for electrophoresis and immunoassay support applications where predictable binding behavior is essential.
• Cellulose Acetate membranes combine high flow rates with exceptional thermal stability.
• Manufactured with a uniform pore structure that maintains consistent retention characteristics across the full membrane surface.

Reproducible particle counting and size distribution analysis start with a membrane surface that captures particles uniformly — the pore consistency documented above ensures your counts reflect the sample, not random variation in the filter. Addressing this directly, compatibility with dilute acids and aqueous buffers covers the matrix range typical in clinical, environmental, and food testing laboratories, reducing the number of membrane types you need to stock. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

Wettability

Hydrophilic

• Enzyme Sterilization - Preserves enzymatic activity during cold sterilization, preventing the denaturation often caused by surface binding.
• Isotope Studies - Used in binding studies where the membrane itself must not interact with the radioactive ligand or the receptor protein.
• Tissue Culture Media - Sterilizes heat-labile media components with minimal hold-up volume, ensuring expensive additives are not wasted.
• Wine Stability Testing - Filters wine samples to check for colloidal stability, ensuring the product will not precipitate during shelf storage.
• Nutrient Analysis - Clarifies water for nitrate/phosphate testing without leaching nitrogenous material that could bias the results.
• Biological Fluid Prep - Clarifies urine or cerebrospinal fluid for clinical chemistry without removing the low-abundance proteins of interest.
