Quality Control

Our Sarpicillin is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including identification, purity assay, and impurity profiling via advanced techniques like HPLC and NMR, to ensure it meets rigorous standards suitable for research and development. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere conditions.
