A microtome has a blade holder on which a blade is mounted, an anti-roll device for supporting a section preparation that has been produced by means of the blade, and a suction device by means of which the section preparation can be picked up by suction and carried off. The suction device has a nozzle, with an adjustably mounted nozzle body, and a suction channel. Provision is made that the anti-roll device is mounted on the nozzle body and is adjustable, in particular pivotable, together therewith.
