About the sample | This is a commercial sample from one of the research laboratories. It is packed in an ampoule under an air atmosphere. The main reason for such a display is not to protect the iodine from the air, but to keep it closed. Otherwise, with time, it can diffuse through plastic and contaminate the surrounding. |
