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.
Claims16
A device for controlling the temperatures in a cooling chamber for a microtome, comprising:
- a control unit for providing an indication of temperatures in the microtome and for indicating a set value, said control unit including a microcontroller having a first temperature control circuit for controlling a temperature of a specimen disposed in the microtome and a second temperature control circuit for controlling a temperature of a cutter of the microtome;
- and
- a setting element common to said first and second control circuits, wherein said first and second control circuits are capable of being programmed to a substantially identical temperature as said set value.
A method of controlling one or more temperatures in a cooling chamber for a microtome, comprising:
- controlling a temperature of a specimen disposed in the microtome;
- controlling a temperature of a cutter of the microtome;
- and
- pre-selecting a set value temperature of the specimen and the cutter with a common setting element such that the temperatures of the specimen and the cutter are capable of reaching a substantially identical temperature as said set value.
A device for controlling the temperatures in a cooling chamber for a microtome, in particular an ultramicrotome, having at least two different temperature control circuits for controlling the temperatures of the specimen and of the cutter, wherein (at least) the control circuit for the temperature of the specimen (8) and the control circuit for the temperature of the cutter (9) have a common setting element (17), by means of which the control circuit can be programmed to an identical temperature as the set value.
