Frequently Asked Questions (FAQs)
1. What is the use of vacuum desiccator in laboratory?
A vacuum desiccator is used in the laboratory to remove air and moisture using a vacuum or vacuum pump. It helps create a dry environment for storing sensitive materials and can also be used for degassing techniques.
2. What are the different types of desiccators in the laboratory?
There are four basic types of desiccators used in the laboratory: standard, automatic, gas purge, and vacuum. The selection of the desiccator type depends on the application, space requirements, and items to be stored. Choosing the right desiccator ensures optimal storage conditions.
3. How does a desiccator prevent moisture from being absorbed?
A desiccator prevents moisture from being absorbed by using a desiccant, which is an adsorbent substance. The desiccant attracts water vapor molecules, collecting and holding them on its surface. Common desiccants include silica gel, activated alumina, clay, and molecular sieves.
4. What is the purpose of using a desiccator while cooling the sample after heating?
Using a desiccator while cooling a sample after heating serves two purposes. Firstly, it prevents moisture from the air from being absorbed by the sample. Secondly, it helps remove any trace amounts of moisture present in the sample, ensuring its integrity and accuracy.
5. What is the temperature of a vacuum desiccator?
The temperature of a heated vacuum desiccator can be adjusted from ambient temperature to a maximum of 170 °C. This adjustable temperature range allows for precise control and customization based on the specific requirements of the experiment or process.
6. What are the two drying agents used in a vacuum desiccator?
The two drying agents commonly used in a vacuum desiccator are sulfuric acid (H2SO4) and phosphorous pentoxide (P4O10). These acidic drying agents are not in direct contact with the solution but are used within the desiccator to maintain a dry environment. It is important to handle these agents with caution as they are aggressive reagents.
7. What should you not do with a desiccator?
It is important not to leave the desiccator open for extended periods, except when transferring samples in or out. The desiccator is designed to provide a dry environment, and leaving it open can compromise its effectiveness. The desiccator can be used to store samples in a dry environment by utilizing the available holes.
