Abstract: A rotational cadaver system is disclosed which incorporates a rotational storage rack. The rotational storage rack includes a first and second shaft and two wheels mounted thereto. The shaft is rotationally mounted on a plurality of legs. A number of branches are radially secured to each wheel and arms are pivotally secured to each branch. The arms include means for receiving a tray upon which a cadaver may be placed. The trays includes means for engagement with mechanical placement and retrieval means. The tray also include means for securing them to various types of autopsy tables. A motor is also provided for turning the shaft varying the position of the cadavers. A method is also disclosed for utilizing the system in conjunction with the performance of an autopsy.

Abstract: A system for identifying and tracking samples of biological material during the preparation of that tissue for microscopic evaluation. The system includes a plurality of colored aqueous embedding media, microscope slides marked to correspond to the colored embedding media, and, optionally, color-coded containers for the embedding media. A process for preparing samples of biological material using the identification system is also provided, as well as compositions for several embedding media including one or more coloring agents.
