A thermal immersion circulator is an electrically powered device that circulates and heats a warm fluid kept at an accurate and stable temperature. It is used in process, environmental, microbiological, hazardous waste, and other laboratories. Since 2005 they have also been used for sous-vide food cooking, a method that uses airtight plastic bags in a water bath at accurately regulated temperatures much lower than usually used for cooking.
