Abstract
A microtome for producing thin sections for microscopy is suggested that has a high level of automation and can be operated ergonomically. The microtome has a sectioning knife, a specimen holder, a first and a second motor unit operating the knife, a control system and an operating unit comprising a first and a second operating element. The first operating element controls the relative displacement between the sectioning knife and specimen holder, while the second operating element adjusts the advance rate of the displacement. The first operating element is a rotating ring and the second element is a rotary knob, concentrically within the rotating ring.
