Histotechnology device

Rotary microtome

The invention relates to a microtome, in particular a rotary microtome (), comprising a micrometer mechanism () having a drive () for producing a relative movement between an object holder () and a blade and a positioning device acting on the micrometer mechanism () to influence the relative movement, the positioning device comprising an advancing device () and a trimming device () interacting with the advancing device (), said microtome being designed and modified with regard to a simple and reliable adjustment of the trimming device () as well as activation/deactivation of a retraction by structurally simple means in such a way that the positioning device has a combined actuating device () for both an adjustment of the trimming device () and also an activation/deactivation of a retraction which can be carried out by means of the advancing device ().
