Membrane Filter, CA, 0.45um, 50mm, Nonsterile, 200 Pk SKU: SF18195

Cellulose Acetate (CA) Membrane Filters, 0.45µm, 50mm - SF18195

Designed to protect sensitive chromatography columns from clogging, the Cellulose Acetate (CA) Membrane Filters delivers exceptional retention of particulates without compromising flow rates. To ensure analytical precision, the unit is constructed with a high-grade Cellulose Acetate (CA) membrane providing a consistent 0.45 cutoff that passes only your target analyte. Delivered as precision-cut discs, these membranes ensure compatibility with all standard filter holders and funnels. 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
• Verified 0.45 retention rating for clarification

You can streamline your sample preparation process significantly by adopting a filtration solution designed to handle your specific volume requirements. You invest significant resources into your samples; safeguarding them with a proven filtration barrier is a cost-effective insurance policy for your lab. 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.
