Quality Control

Our Calcium Tellurite is manufactured under controlled conditions to ensure high chemical purity and batch-to-batch consistency. Quality is verified through a suite of analytical techniques including X-ray diffraction (XRD), inductively coupled plasma (ICP) analysis, and titration methods. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment. We adhere to ISO 9001 quality management principles, and our processes are designed to meet the stringent requirements of research and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from incompatible materials such as strong acids and reducing agents. The container must be kept tightly sealed due to the hygroscopic (moisture-sensitive) nature of the compound.
