Abstract

A rotary microtome includes a crank mechanism for moving an object carriage up and down in a vertical path and a drive mechanism for driving the crank mechanism. The object carriage has a receptacle for a specimen holder. A mass-balancer balances the moveable masses of the microtome. The mass-balancer has a pretensioned, adjustable spring element and a pivotably mounted lever for compensating different inertial forces of the microtome in combination with the spring element. A drawing element connects the lever to the object carriage. The mass-balancer is indirectly connected to the drive mechanism by the drawing element.
