Quality Control

Our Strontium Hydroxide is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) detailing assay, impurity profiles, and physical parameters. Our quality management system adheres to ISO standards, and we can support compliance requirements for REACH and other global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent absorption of moisture and carbon dioxide from the air. Store away from incompatible materials such as strong acids.
