Abstract
An constant temperature circulator for maintaining a liquid at a constant temperature including a housing that encapsulates a controller, a display, a heating element, a temperature sensor, and an electric motor having an impeller. The housing includes a first port and a second port that cooperatively define a chamber that encapsulates the impeller, an aperture and an opening, such that actuation of the impeller when the electric motor is activated by the controller moves the liquid from the aperture, through the chamber and to the opening.
