Quality Control

Our Erbium(III) Chloride is produced under stringent quality management systems to ensure batch-to-batch consistency and high chemical purity. We offer various grades, including standard, high-purity (99.9%, 99.99%, 99.999%), and ultra-dry anhydrous forms, tailored to specific application requirements. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, trace metal analysis, and physical characteristics. Our quality protocols are designed to meet the demanding standards of the optoelectronics and advanced materials industries.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, this material must be stored in a cool, dry place under an inert atmosphere or in a desiccator to prevent moisture absorption. For long-term stability, maintain storage temperatures between 15-25°C. Keep away from incompatible substances.
