A 4-inch desiccator is a compact, laboratory-grade storage vessel designed to preserve moisture-sensitive materials by maintaining a low-humidity environment. Constructed from high-quality borosilicate glass, the desiccator features a tightly sealed lid, typically equipped with a ground-glass or silicone gasket interface, ensuring an airtight seal to prevent the ingress of moisture.
The desiccator includes a removable perforated plate or ceramic disc that holds desiccants such as silica gel or anhydrous calcium chloride in the lower chamber. The upper compartment accommodates samples, reagents, or instruments that require a dry atmosphere for storage or cooling after heating.
Key Features:
-
Internal Diameter: 4 inches (approx. 100 mm), ideal for small-scale laboratory use.
-
Material: Clear borosilicate glass for chemical resistance and visibility.
-
Seal: Airtight design with ground-glass joint or rubber gasket to ensure moisture exclusion.
-
Desiccant Chamber: Lower section designed to hold drying agents.
-
Application: Suitable for preserving hygroscopic chemicals, electronic components, and biological specimens.
The 4-inch desiccator is commonly used in educational, research, and industrial laboratories for maintaining sample integrity and preventing contamination from atmospheric moisture.
