Quality Control

Our Cobalt Chloride is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. The product is tested against rigorous in-house specifications, which may include parameters such as assay, heavy metal content, and insolubles. A Certificate of Analysis (COA) detailing the results is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture.
