An ideal instrument for use in biological educational field engaged in research work. The heavy cast base micro tome spencer type helps in ensuring rigidity and stability with protecting aluminium housing. The feed mechanism used here is independent of the vertical movement of the object block with every complete revolution of the counter balanced drive wheel, the feed pawl engaged precisely into the teeth of the ratchet wheel, feeding on the forward stroke. The ratchet wheel rotates a feed screw which advance. The cone measure distance from left to right across the face of a vertical moving inclined plane. The compound side way provides smooth accurate object travel with 111 micro tome automatic feed. The release device is provided with it to disengages the mechanism automatically and feed is adjustable with the help of knurled knob at the back of micro tome from 1 to 50 microns. From the very first step of 1 micron, feed indicator is graduated in micron. It is conveniently placed on the front that works with the help of cord and pulley system. The locking device which locks the counter balance device wheel securely the object blocks stop at the top of its excursion so that sufficient space for orientation and fixing of blocks is obtained. Ball and flange type object clamp accommodates specimen up to 32 x 27 mm. 3 screw rigidly lock the object clamp into the position. The micro tome is given the finish in chemically resistant paint and hard chrome to the ether parts. They are available with the following accessory.
