Spencer Senior Rotary Microtome

Senior Precision Rotary Microtome is the most precise and uniform sectioning equipment for Medical Colleges. Universities, Research Laboratories, Hospitals and Educational Institutions. The internal mechanism and knife holder rests on a heavy-duty and rigid base to render a shake proof operation. A protective aluminium cover is hinged to the base and swings back so that the interior parts are completely exposed for convenient setting. cleaning, lubrication etc. Feed mechanism is dependent upon the vertical movement of the object block. With every complete revolution of the counter balanced drive wheel, the feed pawl engages with the teeth of the ratchet gear which moves towards and advances the object holder through a cone inclined plane mechanism in precise increments so that the tissues can be sectioned even to a thickness of one micron. When the limit of the feed reaches at the end, a safety device automatically disengages the feed mechanism to prevent jamming and avoid damage to the feed screws.

The feed indicator, graduated in microns, is conveniently located in the front for instant references and its setting is controlled by a knurled knob at the back of the microtome. The sturdy knife holder in addition to knife elevating and levelling provides lateral movement for complete use of knife edge. The angle adjustable up to 30° 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 & tested for Micro structures.

A lever is provided to lock counter balanced drive wheel and specimen block is stopped at the top of its excursion, providing ample clearance space for safety insert and removal of knife and block holders. A quick flip of the lever releases the drive wheel.
