Abstract

A clamping device for a blade-shaped cutting knife of a microtome. The clamping device comprises a base part having a recess, a knife receptacle, an eccentric rod, and setscrews. The knife receptacle includes a blade rest and a pressure plate which is received in the recess of the base part. The eccentric rod is rotatably mounted in the base part and is provided for clamping the cutting knife between the pressure plate of the knife receptacle and the blade rest. The setscrews allow for both lateral and vertical movement of the pressure plate. Thus, by adjusting the setscrews, the edge of the pressure plate may be aligned with the cutting edge of the knife and variation in the thickness or geometry of cutting knife blade may be accommodated.
