Description

American Optical AO 860 Sliding Microtome

The American Optical AO 860 sliding microtome is a fine instrument, ideal for accurately cutting hard objects such as bone, wood, frozen celloidin, and paraffin preparations. The heavy-duty frame, with its horizontal sliding track and precise feed mechanism, is securely mounted on a large hardwood base (21″w x 12″d).

Cutting thickness is adjustable from 1 to 40 microns using the automatic advance mechanism. When the automatic advance mechanism is removed, operation in manual mode allows for even thicker sections.

The American Optical AO 860 sliding microtome has easily adjustable vertical motion of specimen. A crank, geared to the 1/2″ diameter feed screw, allows the specimen to be moved, up to or away from, the cutting position quickly. The universal specimen holder allows X-Y orientation and manual advance and retraction. The specimen is moved precisely either automatically or manually, over a total feed excursion of 42mm. The specimen is oriented to desired angle by a bail and flange clamp with three adjusting screws.

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. The knife setting allows any desired cutting angle, or angle to direction of travel. A scale indicates the angle of tilt of the knife.
