Abstract
A superfusion apparatus for the controlled reaction of a sample within a test chamber through controlled exposure to a series of reagents in a set test sequence is provided for electrical or chemical stimulation to determine if a receptor binding compound is an agonist or antagonist. The superfusion apparatus provides a mass production but meticulously controlled sample environment for controlling temperature, quantity and arrangement of reagents and wash fluids to provide a high reproducability of results which may be compuer assisted. The device has a fully automated mode or a manually operated mode. The fully automated mode allows for the storage and execution of a number of different tests to be performed on the samples due to the provision of desired sequences of test parameters.
