A thermo-electric temperature controller for a liquid chemical bubbler container in which a thermally conductive platform in the housing is heated or cooled by thermo-electric devices for heating or cooling a liquid chemical bubbler container to maintain a preset temperature. The housing is formed with a side opening door to provide an access opening which allows installation and removal of the bubbler container laterally of the housing into a position on the thermally conductive platform. A heat exchanger is provided for the side walls of the bubbler container and includes a first semi-cylindrical section that is mounted at its lower end on the thermally conductive container support platform in heat exchange relation therewith and which extends upwardly around the side walls of the bubbler container, and a second movable heat exchange section which can be moved laterally through the access opening in the housing into opposed relation with the first heat exchange section to form a heat exchange enclosure therewith. The adjacent side edges of the first and second heat exchange members are formed so as to provide interengaging cams arranged to cam the second heat exchange member laterally toward the first heat exchange member as the second heat exchange member moves downwardly into engagement with the thermally conductive container support platform.
