About the sample
This is a commercial sample. It is packed in an ampoule under argon atmosphere covered with paraffin oil. The main reason for such a display is strontium’s high reactivity. Isolation from air and moisture should prevent corrosion of this metal. This sample has been donated by Metodija Najdoski.
