Quality Control

Our Calcium Phosphite is produced under a rigorous quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity and composition. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance protocols.

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 (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture.
