FAQ
Frequently Asked Questions
Extremely rarely. It might appear in specialized contexts like museology (preserving artifacts) or food processing, but it remains a technical term.
A drying agent called a desiccant, such as silica gel, calcium chloride, or phosphorus pentoxide, is placed at the bottom.
No, not in modern English. The agent noun 'desiccator' refers exclusively to the apparatus.
A desiccator is typically for laboratory use, creating a static dry environment. A dehydrator (e.g., for food) actively circulates warm air to remove moisture.
