<p>A laboratory incubator (10) having an improved temperature control assembly (14) that more effectively maintains the temperature within the incubator in a desired range and more accurately controls the rate of heat loss from the laboratory incubators as ambient temperatures rise. The incubator includes a housing (12) having an enclosed incubation chamber (18) therein; a heater (22) positioned within the housing for heating the chamber; a cooling device (24) positioned within the housing for cooling the walls of the housing; and a controller (26) for controlling the operation of the heater and the cooling device to maintain a temperature in the chamber within a set temperature range. The cooling device includes an electrically operated peltier device operable to both cool the chamber and to assist the heater in heating the chamber.</p> |
