Quality Control

Every batch of Erigoster B is produced and controlled under a strict quality management system. Our products undergo rigorous analytical testing, including chromatographic purity assays and identity confirmation, to ensure they meet the exacting standards required for research and development applications. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment. We support compliance needs for projects requiring materials traceable to cGMP or other regulatory guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep the container tightly sealed to protect from moisture. For long-term storage, consider inert atmosphere conditions.
