Quality Control

Our L-Ornithine Sulphate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, specific rotation for chiral identity, and heavy metal screening, to ensure it meets the high standards required for pharmaceutical and nutraceutical applications. Certificates of Analysis (COA) confirming compliance with in-house specifications 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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of moisture from the air, which can lead to caking or degradation.
