| 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.
