Use a Desiccator
A desiccator will provide an atmosphere with low humidity for the storage of
samples, precipitates, crucibles and other equipment.
Desiccants have a limited capacity to absorb moisture from the atmosphere.
Learn how to tell when your desiccant is no longer effective.
Do not place hot items in a desiccator. As the items cool, they can create a partial
vacuum in the desiccator and may spill when the desiccator is opened and air
rushes in.
