Quality Control

Our Holmium products are manufactured and tested under strict quality management protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) detailing purity, metallic impurities, and other critical parameters. Our quality systems support compliance with relevant industry standards for research and high-tech manufacturing. For specific grade requirements or regulatory documentation (e.g., REACH), please contact our technical support team.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry place, ideally under an inert atmosphere (e.g., argon) to prevent oxidation. Recommended storage temperature is 15-25°C. Keep away from strong acids and oxidizing agents.
