Quality Control

Our Spiro-Meotad is produced under stringent quality management protocols to ensure batch-to-batch consistency and high performance in sensitive applications. Each lot is analyzed to confirm identity, purity, and the absence of critical impurities. Certificates of Analysis (COA) detailing all relevant specifications are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
