Quality Control

Our Lumogallion is produced under a strict quality management system to ensure batch-to-batch consistency and high purity for sensitive analytical applications. Each lot undergoes rigorous testing including identification, assay, and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing purity, performance in fluorometric assays, and other critical parameters is provided with every shipment to support your research and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants.
