Quality Control

Every batch of our cyanine dye is produced and tested under strict quality management protocols to ensure consistent performance and purity for sensitive optical applications. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, absorbance maxima, and impurity profiles. Our commitment to traceability and documentation supports compliance in regulated research and manufacturing environments.

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 low-humidity environment to prevent degradation. For long-term storage, consider the use of desiccants.
