A mains electricity (AC-powered) device designed for total elimination and/or inactivation of microorganisms from medical/dental devices and related products using boiling water as the sterilizing agent. It typically consists of a container intended to be filled with water, in which devices are submerged, and an apparatus to boil the water for a specific period. The device is almost exclusively used in remote areas, at home (e.g., for baby bottle sterilization), and/or in emergency situations.
