AO 860 Sliding Microtome

The AO Sliding Microtome model 860 includes a standard knife holder, specimen holder, base mounting board, bottle of microtome oil, one new Rankin Biomedical stainless steel knife, 1" spacer block, and a new freezing stage. This fine instrument is ideal for accurately cutting hard objects such as bone, wood, frozen celloidin, and paraffin preparations. The universal specimen holder allows X-Y orientation, manual advance & retraction. The thickness of specimen sections can be adjusted from 1 to 40 microns using the automatic advance mechanism. In manual operation the automatic advance mechanism is easily removed for even thicker sections. A crank geared to the 1/2" diameter feed screw allows the object to be moved up to, or away from, the cutting position quickly. The specimen is moved precisely either automatically or manually, over a total feed excursion of 42mm. The knife setting allows any desired cutting angle, or angle to direction of travel. It has easily adjustable vertical motion of specimen. The knife is clamped to a 3 1/2"W x 6"L block, which slides on a horizontal surface at the top of the main casting. A scale indicates the angle of tilt of the knife. The specimen is oriented to desired angle by a bail and flange clamp with three adjusting screws. The heavy frame with a horizontal sliding track and precise feed mechanism is mounted on a large hardwood base. The freezing stage (including 2 fiberboard rings) operates on ethanol and dry ice. The freezing platform measures 3 1/4" x 4" and is suitable for cutting blocks up to 3" x 2". AO 969 Pike Oil is recommended for lubrication. An optional adjustable knife holder ($750), if available, can be used in place of the standard knife holder. A reconditioned Sturkey 240mm Stainless Steel Flatback Knife is available for $400. Dimensions are 17 1/2"L x 11"W x 11 1/2"H. Net weight is approximately 80 lbs and shipping weight is approximately 150 lbs.
