Immuno histo chemistry tissue processing system

A tissue processing system for processing a laboratory slide, said system comprising:

• an enclosure comprising interconnected structural members;
• a slide carriage mounted to one of the interconnected structural members for receiving the laboratory slide;
• a cartridge that is positioned at an elevation above the laboratory slide, wherein the cartridge comprises discrete wells that are each filled with reagent fluid, each discrete well having an exit port through which fluid is distributed directly onto the laboratory slide, wherein each exit port is positioned at an elevation directly above the laboratory slide;
• a manifold that is fixedly mounted to one of the interconnected structural members and positioned at an elevation directly above the laboratory slide, wherein the manifold comprises a first fluid passageway including an inlet port and a plurality of outlet ports that are fluidly connected to the inlet port by internal passages and positioned to direct a fluid stream onto the laboratory slide, wherein the outlet ports are fluidly isolated and fluidly disconnected from the exit port of each discrete well of the cartridge, and wherein the outlet ports are stationary and do not move with respect to the enclosure;
• and
• means for moving the slide carriage relative to the outlet ports and the exit port to adjust a point on the laboratory slide at which fluid is delivered onto the laboratory slide by either the manifold or the cartridge.
