Quality Control

Our Lithium Bromide is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, heavy metal content, and other critical parameters. A Certificate of Analysis (COA) is provided with every shipment, detailing the results of tests such as assay, chloride content, sulfate content, and loss on drying. We support compliance with relevant industrial and regulatory standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, the product must be stored in a cool, dry, and well-ventilated area. The storage temperature should be maintained between 15°C and 25°C (59°F and 77°F). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking and reduced efficacy.
