A heated cabinet or chamber used for drying, heating, or sterilizing objects, particularly in laboratory or medical contexts.
From French 'étuve,' from Old French 'estuve,' related to Latin 'ex-' (out) and possibly 'stufa' or 'stupa' (heated chamber). The term refers to a device that uses heat, and entered English from French scientific terminology.
The etuve was an essential piece of early medical and scientific equipment—before modern ovens and autoclaves, these heated chambers were how scientists sterilized their tools and dried their samples, making them crucial for preventing contamination.
