Zusammenfassung: | A system and apparatus for precision temperature control of thermal bead baths used in biological laboratories to heat biological samples is disclosed. The system has 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 is in the recirculation pathway and is positioned to draw air through the air extraction port. At least one thermal sensor is connected to a control and is disposed in close proximity to one of the air injection ports. Beads used in thermal bead baths 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. |
