Abstract

A device for controlling the temperatures in a cooling chamber for a microtome, in particular an ultramicrotome, comprises at least two different temperature control circuits for controlling the temperatures of the specimen and of the cutter. The control circuit for the temperature of the specimen (8) and the control circuit for the temperature of the cutter (9), as well as, if appropriate, the control circuit for the temperature of the chamber gas, have a common setting element (17), such that the control circuit can be programmed to an identical temperature as the set value.
