Quality Control

Our Proxan Sodium is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure it meets high-purity standards and consistent performance. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles 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 controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after use to prevent absorption of atmospheric moisture. For long-term storage, consider using desiccants.
