Quality Control

Our Antibiotic 308 is manufactured and tested to meet the rigorous standards required for pharmaceutical applications. Quality assurance protocols are designed to ensure batch-to-batch consistency, high purity, and compliance with relevant guidelines. A comprehensive Certificate of Analysis (COA), detailing identity, purity, and impurity profiles, is provided with each shipment to support your quality systems.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
