Quality Control

Our Calcium Iodide Tetrahydrate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and composition. Certificates of Analysis (COA) documenting results for assay, heavy metals, and other critical parameters are available upon request to support your quality assurance protocols.

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 opening to prevent absorption of atmospheric moisture.
