Quality Control

Our Calcium Oxide is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity. Production adheres to relevant industrial standards, and each lot is accompanied by comprehensive analytical documentation. Certificates of Analysis (COA) detailing assay, impurity profiles, and physical specifications are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed in a cool, dry, and well-ventilated area. Store away from incompatible materials such as strong acids and organic solvents. Typical recommended storage temperature is 15-25°C.
