A desiccator is commonly used to dry solids. It consists of a thick-walled glass container and a lid. It can be evacuated and heated. A drying reagent (e.g. H₂SO₄, P₄O₁₀, CaCl₂, Drierite, etc) is added in a bowl on the bottom of the desiccator to absorb a 'volatile solvent'. The drying can be carried out at ambient pressure or in vacuo. In either way, the ground glass joints have to be lubricated properly with special grease (very expensive!!). The bowl should be covered with tape and plastic netting to provide protection in case the desiccator implodes. If you have to evacuate the desiccator, make sure that you place it in a safe spot afterwards where nobody can knock it over. Attach a label on the top which informs other potential users about the content e.g. Compound A over sulfuric acid (James Miller).
