ABSTRACT:
A method and device for embedding in a plastic block a selected part of a specimen being prepared for microscopic examination. The device has a frame with a horizontally disposed base member and a vertically disposed headboard and footboard. A mold jockey slides longitudinally along the base member. A slide jocket slides transversely to the direction of motion of the mold jockey and supports a glass microscope slide horizontally above the mold jockey, such that a mold held in the mold jockey may be moved beneath any selected location on the microscope slide. A constricted mouth of a plastic mold held in the mold jockey is pressed against a plastic impregnated specimen held to the underside of the microscope slide. The plastic is cured, embedding a section of the specimen in the face of the plastic block formed within the plastic mold. After curing, excess plastic is removed, leaving the selected portion of the specimen embedded in the end of the plastic block, with a known orientation and location.
