Myco Supply carries both an indicating drierite and a non-indicating drierite. Indicating drierite is blue when dry and changes to pink upon absorption of moisture. The color change is pronounced and clearly visible. This makes indicating drierite valuable when it is necessary to know with certainty that dryness is being maintained and to signal when the drying agent should be refreshed. It has the same efficiency as regular drierite, and somewhat greater capacity due to the desiccanting effect of the cobalt chloride. The non-indicating white drierite is suitable if moisture indication isn't important in your operation.

For the regeneration of drierite, the granules may be spread in layers one granule deep and heated for 1 hour at 210° C or 425° F. The regenerated material should be placed in the the original glass container and sealed while hot. Each glass jar contains one pound of drierite.
