Quality Control

Our Rarechem Al Bo 1277 is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high performance. Production adheres to relevant industrial standards, with rigorous testing for chemical composition, particle size distribution, and crystalline structure. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and key physical parameters is provided with each shipment to guarantee specification compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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, which can affect product performance. Keep away from incompatible materials such as strong acids.
