Quality Control

Our Lutetium Oxide is produced under a stringent quality management system. Each batch undergoes comprehensive analysis to ensure it meets high-purity standards, typically ranging from 99.9% to 99.999% (3N to 5N), tailored to application requirements. Certificates of Analysis (COA) detailing purity and trace metal impurities are provided with every shipment. We support compliance with relevant industry standards, and specifications can be adjusted to meet specific customer or research-grade needs.

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). This material is hygroscopic (moisture-sensitive) and should be kept in a desiccated environment to prevent absorption of water and carbon dioxide from the air.
