What is a Desiccator and How is it Used?
Overview of Desiccators
- The desiccator is a laboratory device designed to remove moisture from the air inside, allowing for the storage of substances sensitive to water.
- It consists of several parts: a thick glass capsule with a sliding lid and a perforated base, typically made of ceramic or plastic.
Functionality and Components
- To function effectively, desiccators require a drying agent, usually silica gel, placed in the lower cavity beneath the perforated base. This gel absorbs any moisture that enters the container.
- Proper sealing is crucial; all ground joints should be greased to ensure airtightness before adding silica gel and closing with the perforated base.
Usage Instructions
- After assembling the desiccator with samples inside, if vacuum conditions are needed, connect a vacuum pump to the valve to minimize air presence.
- Silica gel often includes an indicator that changes color when saturated with water; this signals when it needs drying in an oven for reuse.
