Abstract

A microtome, especially an ultramicrotome, is disclosed in which a foward-feed system for the specimen arm and/or knife of the microtome comprises, a stepping motor which is controlled by a pulse generator and which shifts the specimen arm and the knife relative to each other by an appropriate amount of forward-feed in accordance with a forward-feed value which is set at one of a plurality of preselector switches. In order to facilitate quick switching-over from one forward-feed amplitude to another, permitting the selection of forward-feed amplitudes which differ by an order of magnitude, for example if semi-thin sections are to be produced during a run of ultra-thin sections, the forward-feed amplitudes set by the preselector switches can be switched according to choice to the pulse generator for the stepping motor, by means of a changeover switch. This arrangement enables the operator to alter the forward-feed amplitude by one manual action, without disturbing the ongoing operation.
