Conxport Spencer Rotary Microtome

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 cleaning, lubrication, setting, etc. the feed mechanism is dependent on the vertical movement of the object block. With every complete revolution of the counterbalanced drive wheel, the feed pawl engages precisely onto the gear which moves towards and advances the object holder through a cone, inclined plane mechanism in such 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 feed mechanism to prevent jamming and damage to the feed screws. The feed indicator is located in the front and the 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 micron each. The sturdy knife holder is an addition to knife elevating and leveling and provides lateral movements for complete use of the knife edge.The angle adjustable 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 microstructures. It is furnished in an attractive hammer tone finish and is packed with the following accessories in a wooden case along with an operating manual.

• Tissue Embedding cassette 1 packet of 50 pcs
