Quality Control

Our Holmium Oxalate is produced under stringent quality management protocols. Each batch undergoes comprehensive analysis to verify identity, purity, and conformance to agreed specifications. We provide full traceability and support our products with detailed Certificates of Analysis (COA), which are available for every shipment. Our quality systems are designed to meet the rigorous demands of industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
