Quality Control

Our Dilithium Sulphite is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, impurity profiles, and moisture content. We adhere to relevant industry standards for laboratory and technical-grade chemicals.

Storage

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