Abstract
A two-part histologic tissue processing and embedding structure comprises an open-ended base pan and a perforated top member. For processing, the base pan and top may be sna-fitted together to form a compact housing for holding and transporting the tissue specimens through the various processing liquids. For embedding, the top is inverted so that the top and base pan may be loosely seated together as a mold for receiving paraffin which solidifies to embed the tissue specimen. For slicing, the base pan is used as a microtome clamp aligning device and is then removed and the top serves a mounting device for mounting the embedded specimen in a microtome clamp during slicing, and for storage the base pan may be secured back onto the top and placed over the remaining unsliced embedded specimen for protection.
