Quality Control

Our Strontium Propionate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and heavy metal content. Certificates of Analysis (COA) documenting these results are provided and can be tailored to meet specific customer or regulatory requirements, including those for food-grade applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption and caking.
