Abstract: Techniques herein provide a hot plate with extremely precise and uniform temperature control. Such techniques herein include a hotplate containing a fluid and being configured to maintain and/or control a phase mixture of this fluid. A corresponding temperature of the phase mixture in turn heats the hot plate. A given phase change temperature is controlled by material selection and material additives. Accordingly, a temperature of an entire hot plate chassis can be controlled by maintaining a phase change mixture of liquid and solid material, or gas and liquid material, thereby providing an exact temperature within 0.01 to 0.0001 degrees uniformly across the entire hot plate chassis.
