Quality Control

Our rubidium is produced and handled under stringent quality protocols to ensure high purity and batch-to-batch consistency for industrial and research applications. We provide comprehensive Certificates of Analysis (COA) detailing purity, metallic impurities, and packaging integrity. Quality assurance adheres to relevant material specifications, and custom purity grades are available to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its nature as an easily oxidized (store under inert atmosphere) metal, rubidium must be stored and handled under an inert atmosphere such as argon or mineral oil to prevent violent reaction with air and moisture. Store in a cool, dry, well-ventilated area away from incompatible materials like water, acids, and halogens.
