Abstract
A cryostatic microtome has a cryostatic chamber, and a microtome arranged in the cryostatic chamber, and including a specimen holder and a knife holder. In order to maintain high dynamics with respect to temperature changes and thereby a rapid matching to changing specimen consistencies, a coolable specimen holder and a coolable knife holder are provided, so that both the temperature of the specimen holder and also the temperature of the knife holder are adjustable independently of each other. Sections of improved quality can be attained by the free and independent temperature adjustment of the knife and specimen.
