Quality Control

Our Diam 4 is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) detailing all test results is provided with each shipment.

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 sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, and open flame.
