Quality Control

Our Strontium Chloride Dihydrate is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and physical properties. Certificates of Analysis (COA) documenting results for key parameters such as assay, heavy metals, and loss on drying are available upon request. We adhere to relevant industry guidelines to support applications in technical and research sectors.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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, which can lead to caking or degradation.
