CA Membrane Circle (OE 66), 0.2um Pore Size, 110mm Circle (50 pcs) SKU: 10404126

Cellulose Acetate (CA) Membrane Filters - 10404126

Precision-manufactured Hydrophilic membrane with a verified 0.2 pore structure delivers consistent retention performance across demanding laboratory filtration workflows. Additionally, precision membrane geometry balances retention sharpness with sustainable flow rates, minimizing the pressure buildup that leads to premature filter replacement. Controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

• Particularly well suited for electrophoresis and immunoassay support applications where predictable binding behavior is essential.
• Offer improved chemical resistance to low molecular weight alcohols compared to MCE.
• Manufactured with a uniform pore structure that maintains consistent retention characteristics across the full membrane surface.
• Cellulose Acetate membranes combine high flow rates with exceptional thermal stability.
• Naturally hydrophilic and compatible with aqueous biological solutions without pre-wetting or surfactant treatment.

Microbial enumeration methods require complete retention at the rated pore size and a surface that supports colony growth without inhibition, and the membrane specifications above confirm both requirements for your culture-based workflows. The thermal tolerance of cellulose acetate allows autoclaving for applications where you need a sterilized membrane seated in your holder before introducing the sample, simplifying aseptic technique in your workflow. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Hydrophilic

• Enzyme Sterilization - Preserves enzymatic activity during cold sterilization, preventing the denaturation often caused by surface binding.
• Low Binding Filtration - Ideal for filtering dilute protein solutions where maximum recovery is needed to maintain experimental accuracy.
• Wine Stability Testing - Filters wine samples to check for colloidal stability, ensuring the product will not precipitate during shelf storage.
• Groundwater Filtration - Filters dissolved metals samples without adsorption, ensuring the filtrate represents the true environmental state.
• Biological Fluid Prep - Clarifies urine or cerebrospinal fluid for clinical chemistry without removing the low-abundance proteins of interest.
• Nutrient Analysis - Clarifies water for nitrate/phosphate testing without leaching nitrogenous material that could bias the results.
