SUMMARY The design and construction of a thermoelectric cooling stage and its use for the determination of the supercooling points of microscopic organisms is described. Stage cooling is produced by a Peltier unit with a refrigerated circulator as a heat sink. Control is achieved by automatically comparing the temperature input to a reference ramp and varying the power input to the Peltier module accordingly.
