Quality Control

Our Dipotassium Telluride is produced and handled under controlled conditions to ensure batch-to-batch consistency and high chemical purity. Quality is verified through a suite of analytical techniques including assay, identification, and impurity profiling. A Certificate of Analysis (COA) detailing specific results is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and oxygen-sensitive nature, this material must be stored under an inert atmosphere (e.g., argon or nitrogen) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. The container should be kept tightly sealed when not in use to minimize exposure to moisture and air.
