ABSTRACT:
A microtome, in particular a rotational microtome, comprising a base frame (10) on which is provided a specimen holding device (32) for performing a vertical cutting movement. The microtome further has a knife holding device (12) for a cutting element (24) which is formed by a cutting knife (26) or a cutting blade combined with a blade holder. A considerable cost saving and a substantially enhanced level of torsional stiffness and stability when the cutting forces take effect is achieved in that in the microtome the knife holding device (12) has two side plate portions (14) which project forwardly from the lower end portion (16) of the base frame (10).
