The Microprocessor Tissue Processor is a productivity tool for the electron microscopy laboratory. It uses a proven robotics system to move baskets of tissue from one vial to another and agitates at the time and force program, at the temperature desire. Microprocessor Tissue Processor is the only system that uses sealed vials for all reagents. With any other carousel system, the operator is potentially exposed to multiple hazardous vapors upon trying to inspect the process, change vials, retrieve the stack, etc.
