Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and easily oxidized nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to equilibrate to room temperature before opening to prevent moisture condensation.
