Quality Control

Our 4-o-Methyl-Glucuronoarabinogalactan is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing parameters such as carbohydrate profile, moisture content, and microbial limits are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept sealed to prevent moisture absorption, which can affect product performance and stability.
