Abstract
A system for precision temperature control of thermal bead baths used in biological laboratories to heat biological samples. An insulated outer shell and an inner shell sealed together to form a recirculation pathway. The inner shell has an air extraction port opening into the recirculation pathway and at least one air injection port opening into the recirculation pathway. A fan in the recirculation pathway draws air through the air extraction port. A thermal sensor is connected to a control and is disposed in close proximity to one of the air injection ports. Thermal beads are placed in a mesh basket inside the inner shell. The fan draws air from the inner shell through the beads and into the recirculation pathway, where the air is heated by a thermal element. The air flows past the thermal element and through the air injection ports back into the inner shell.
