Quality Control

Our Strontium Sulfite is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. The product is tested against rigorous in-house specifications, which typically include parameters for assay, heavy metal content, and insolubles. A Certificate of Analysis (COA) detailing the results for each production lot is provided to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its property of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep container tightly sealed when not in use to minimize exposure to air and moisture.
