Senior precision rotary microtome is as per Spence A.O. 820 and is the most advanced sectioning equipment for medical colleges, universities, research laboratories, hospitals and educational institutions. The internal mechanism and knife holder rest on a heavy and rigid base to render a shake proof operation. The latest designed protective cover is hinged to the base and swings back so that the interior parts will be completely exposed for convenient cleaning, lubrication & setting etc the feed mechanism is dependent on the vertical movement of the object block. With every complete revolution of the counter balanced drive wheel the feed pawl engages precisely on to the teeth of the ratchet gear which moves towards and advances the object holder thought a cone, inclined plane mechanism in such a precise increments that tissues can be sectioned even in one micron thickness. When the limit of the feed is reached at the end, a safety device automatically disengages the fee mechanism to prevent jamming and damage to the feed screws.

The feed indicator is located in the front and feed setting is controlled by a knurled knob at the back of the microtome, to adjust section thickness from 1 50 microns in steps of one microns each. The sturdy knife holder in addition to knife elevating and leveling provides lateral movements for complete use of knife edge.

The angle adjustable up to 300 is indicated on a reference scale. The knife supplied with the microtome is fabricated from high carbon fine grain tool steel which is heat treated for proper temper and tested for micro structures. It is furnished in attractive hammer tone finish and is packed with following accessories in a wooden case along with operating manual.
