FunctionDesiccators are used to dry substances by placing them inside together with a hygroscopic substance like an acid or a salt. They can also be used to store substances at a constant, controllable humidity level by placing a substance with specific hygroscopic properties, and which has already absorbed water, in the desiccator.
In desiccators of the shape seen in this object, the hygroscopic substance is usually placed in the lower level.
This desiccator's lid has a hook to hang objects from the above (See object No. 4350).
