Quality Control

Our Cesium Tungstate is produced and tested under stringent quality management protocols to ensure batch-to-batch consistency and purity. Each lot is analyzed for key parameters including assay, impurity profiles, and physical characteristics. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment and is available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, the material must be stored in a cool, dry place with minimal humidity exposure. Recommended storage temperature is between 15°C and 25°C. Keep the container tightly sealed when not in use to prevent moisture absorption and caking.
