Quality Control

Our Egs Crosslinker is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay by HPLC and identification by spectroscopic methods, to ensure high purity and consistent performance. A detailed Certificate of Analysis (COA) is provided with each shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation by atmospheric moisture.
