ABSTRACT:
A microtome object holder clamping assembly is disclosed, having utility for positioning a ball-mounted specimen plate in a spatially fixed manner, but which is selectively repositionable by pivotal and/or rotational movement to dispose the specimen plate at any desired orientation relative to the microtome knife element. The object holder clamping assembly comprises first and second clamping members, one of which has a generally V-shaped, conical spherical contoured channel therein which is disposable in proximity to a spherically contoured cavity in a second clamping member, whereby the ball of the ball-mounted specimen plate may be clamped in a three-point contacting arrangement. The microtome object holder clamping assembly of the invention may be usefully employed in a variety of microtome structures, including microtome cryostats, for sectioning of selected specimens.
