1. Neither can these hydrates be dried using standard desiccator methods. 2. A stopcock may be included to permit the desiccator to be evacuated. 3. The crucible with the sample and lid is allowed to cool in a desiccator . 4. To prevent adsorption of moisture from the surrounding air, glassware is cooled in a desiccator . 5. The desiccator contains desiccant to absorb moisture from the air inside, so the air inside will be completely dry. 6. Because RbCl is hygroscopic, it must be protected from atmospheric moisture, e . g . using a desiccator . 7. Where a desiccator alone is unsatisfactory, the sample may be dried at elevated temperature using Abderhalden's drying pistol. 8. Often some sort of humidity indicator is included in the desiccator to show, by color changes, the level of humidity. 9. A desiccator is a heavy glass or plastic container used in practical chemistry for making or keeping small amounts of materials very dry. 10. They should also be coated ( typically with germanium ) and stored in a desiccator , to minimize interaction with atmospheric water vapors.
