Quality Control

Our Strontium Selenite is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Production adheres to current Good Manufacturing Practices (cGMP) where applicable. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles, available upon request. We can tailor specifications to meet the requirements of pharmaceutical, electronic, and research grades.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from incompatible materials such as strong acids and reducing agents. This material is moisture-sensitive; ensure containers are kept tightly sealed to prevent absorption of atmospheric moisture.
