Quality Control

Our Spiramycin is produced and tested under a strict quality management system to ensure batch-to-batch consistency and reliability. Quality assurance includes comprehensive testing for identity, purity, and potency, aligning with industry standards for pharmaceutical and veterinary use. A Certificate of Analysis (COA) detailing specific results for assay, related substances, and microbiological purity is provided with each shipment to guarantee compliance with your specifications.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
