Quality Control

Our Levofloxacin Lactate is manufactured under strict quality management systems, targeting compliance with pharmaceutical-grade (USP/EP) standards. Every batch undergoes comprehensive analytical testing including HPLC for assay and impurity profiling. A Certificate of Analysis (COA) detailing purity, identity, and specific tests is provided with each shipment to ensure traceability and regulatory support.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent degradation. For long-term storage, consider conditions under an inert atmosphere.
