Quality Control

Our Barium Hydroxide is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure it meets precise chemical and physical specifications, including assay, heavy metal content, and clarity of solution. A Certificate of Analysis (COA) detailing purity and test results is provided with every shipment to guarantee traceability and compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids. Due to its hygroscopic nature, the container must be kept tightly sealed to prevent absorption of moisture and carbon dioxide from the air, which can degrade the product quality. Recommended storage temperature is 15-25°C.
