Turbidity 40 NTU

Turbidity Standard Solution 40 NTU is a high-purity, pharmacopeial-grade solution used in pharmaceutical, environmental, and analytical laboratories for the calibration and testing of turbidimeters and nephelometers that measure low to moderate turbidity levels in aqueous samples.

🏭⚗️ Production
Produced under strictly controlled conditions to ensure high purity, accurate turbidity, and minimal contamination. The solution is prepared using stabilized formazin or equivalent polymeric dispersions to achieve a precise turbidity of 40 NTU and is supplied in sealed, light-protected, chemically resistant containers to prevent particle settling, contamination, or degradation. Quality is verified according to pharmacopeial and analytical standards for turbidity stability, uniformity, and reproducibility.

🔬 Properties
A clear to slightly opalescent suspension with a defined turbidity of 40 NTU. Stable under proper storage conditions but may show minor particle settling if exposed to extreme temperatures, strong light, or prolonged storage; gentle mixing restores uniformity.

🧪 Applications
Used in pharmaceutical, environmental, and water quality laboratories for the calibration and accuracy testing of instruments measuring low to moderate turbidity. Ideal for validating nephelometric and turbidimetric methods in drinking water, effluent monitoring, and laboratory quality control procedures requiring low turbidity reference standards.

⚠️ Safety
Generally considered low-hazard but should be handled with care to avoid ingestion, inhalation of aerosols, or contact with skin and eyes. Wear appropriate protective gloves, goggles, and lab coat when handling. Store in a cool, dry place in tightly sealed, light-protected containers. Dispose of according to laboratory and environmental safety regulations.
