ABSTRACT:
Disclosed is an apparatus for slicing tissue sections from a frozen specimen for microscopic analysis or the like without allowing tissue debris or dust to become airborne and thereby transport bacteria or viruses from one specimen to other specimens or to an operator. This is achieved by slicing the specimen while submersed in a subzero dielectric liquid and passing a conveyor, such as a statically charged web or film, adjacent the point of sectioning so that the tissue sections and associated tissue debris generated therewith are attracted to the web and adhere thereto. The conveyor transports the tissue sections, and associated debris adhering thereto, through a sterilizer and staining tanks whereafter the tissue is transferred to a slide for microscopic examination.
