HEATING DEVICE WITH A PHASE CHANGE TEMPERATURE CONTROLLER A heating device demonstrating an improved temperature control and a method of main taining a steady-state temperature at an essentially constant value are disclosed. The heating device comprises a thermally-conductive chamber containing a material capable of undergoing a phase change at or near the desired steady-state temperature. The heating device is useful in a variety of applications, and especially applications requiring the maintenance of a steadystate temperature over relatively long time periods, such as in diagnostic assays of biological fluids, like the hemoglobin AlC (HbAlc) assay of whole blood.
