  • Hotplate stirrer
    Patent number: 11504684
    Abstract: A hotplate device has a body with a platform for receiving a vessel that contains a sample to be heated. A heating element, arranged under the platform, provides heat to the platform, based on a set temperature and a measured temperature as sensed by at least one temperature sensor, proximate to the platform. A controller located in the body directs electrical power to the heating element. As a safety feature, a wireless communication feature allows a user to enter set temperature instructions from a mobile device when communication with the mobile device is enabled and established. A proximity feature, when enabled, allows the user to enter instructions only as long as the user remains in a predetermined proximity of the hotplate device.
