Quality Control

Our Triammonium Phosphate Trihydrate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, composition, and physical properties. Certificates of Analysis (COA) documenting these results are provided to guarantee traceability and consistency for your production 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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption and caking.
