Drierite is a laboratory
grade desiccant. Please be advised that there are different grades of desiccants.
Unlike store bought, or "paint grade" desiccants that only absorb a small percentage
of their mass. Drierite instantly absorbs 6.6 weight percent water by chemical
action, creating the hemihydrate of calcium sulfate. drierite granules have 38
percent pore space volume, which accounts for its high absorption capacity.
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 desiccating effect
of the cobalt chloride. The non-indicating white drierite is suitable if moisture
indication isn't important in your operation.
Regeneration:
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.
Myco Supply carries
both one pound bottles of Drierite as well as larger five pound bottles of both
non-indicating and indicating Drierite.
