Quality Control

Our Tris(2,2,6,6-Tetramethyl-3,5-Heptanedionato)Ytterbium is manufactured under controlled conditions and undergoes rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Certificates of Analysis (COA) detailing purity, identity, and specific impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, it is recommended to handle and store the material under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation. Recommended storage temperature: 2-8°C for long-term stability.
