Quality Control

Our Sodium Glycerophosphate Hydrate is produced under strict quality management systems. We offer grades compliant with Pharmaceutical (USP/EP) and Food Grade (FCC) standards, ensuring suitability for sensitive applications. Every batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling. Certificates of Analysis (COA) documenting purity, heavy metals, and microbiological data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed immediately after use to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
