Quality Control

Our Lactaroviolin is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and identity confirmation via spectroscopic methods (IR, NMR). We provide detailed Certificates of Analysis (COA) with every shipment, ensuring traceability and compliance with your research or production 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 light-sensitive and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
