A Programmable Temperature-Controlled Microscope Stage for Biomedical Investigations

A microprocessor-based device was designed to work in conjunction with a Cambion bipolar controller to generate temperature regimens consisting of predetermined rates of heating and cooling interposed with intervals of time at fixed temperature. The composite device is used for maintaining small pieces of tissue at fixed temperature on the stage of a microscope. The device employs four integrated circuit chips including one EPROM.
