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 (,) and the control circuit for the temperature of the cutter (,), as well as, if appropriate, the control circuit for the temperature of the chamber gas, have a common setting element (,), such that the control circuit can be programmed to an identical temperature as the set value.

Chamber for freeze-drying by cryosorption

A method for metal-mirror cryofixation of bio-medical or similar technical specimens in which a specimen is brought into contact with a highly polished, cooled metal mirror in order to cool at least a marginal zone of the specimen suddenly to a low temperature. In order to avoid deformation of the specimen caused by freezing, provision is made, immediately after the first contact between the specimen and the metal mirror, to press the latter against one another by an additional independent force until the specimen is completely frozen. A cryofixation device for this purpose comprises a force generating device, for example, a separate power storage device (135) which, under control, functions after contact between the specimen (106) and metal mirror (102), in other words exerts the additional force between the specimen and the metal mirror (FIG. 7).

Cryogenic-fixation apparatus comprises a light source, a beam from which enter cooling liquid in a bath, through a window in the underside of the bath. The beam can be directed upwardly by means of a reflecting prism. When a lid of the bath is closed, the beam leaves the space defined by the path through an exit port in the lid, and is incident upon a specimen mounted on a specimen holder located above the exit port, the specimen holder being secured to an injector rod.
