DescriptionThis Boecker microtome is made of brass. The rectangular base holds a tubular specimen holder driven by a vertical screw mounted below it. On either side of the specimen holder is a pillar. These pillars support a set of three thick brass plates with slots to accommodate the specimen tube. The lowest horizontal plate has a dovetailed track. The middle horizontal plate slides in this track at right angles to the lower plate. The top horizontal plate slides at right angles to the middle plate in a similar track on the middle plate. The top and middle plates move together when the vertical operating handle is pulled to the right. The steel knife is held in a clamp attached to the top plate.
