A desiccator vacuum is a laboratory apparatus used to store and preserve moisture-sensitive materials. It typically consists of a clear, airtight container and a source of vacuum, such as a pump or a vacuum valve, to remove the air and create a low-humidity environment inside the container.
The materials being stored are placed on a shelf inside the container, and the vacuum is applied to remove any air and moisture that might cause degradation of the materials over time.
Desiccator vacuums are commonly used in chemical, pharmaceutical, and scientific research to store samples, reagents, and other sensitive materials. They help to prolong the shelf life and maintain the quality of the materials being stored.
