Quality Control

Our Carbonic Acid, Copper Salt is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent composition, purity, and performance. Key parameters such as copper content, carbonate content, and impurity levels are verified. Certificates of Analysis (COA) documenting these results are available for every shipment to support your quality assurance protocols.

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. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent absorption of atmospheric moisture.
