Quality Control

Our Germanium Ditelluride is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed for critical parameters including purity, crystalline phase, and metallic impurities. A Certificate of Analysis (COA) detailing these results is provided with every shipment to support your quality assurance and R&D documentation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is moisture-sensitive (hygroscopic) and should be handled under an inert atmosphere (e.g., argon or nitrogen) for long-term storage to prevent oxidation.
