ABSTRACT:
To transfer fluids between receptacles at controlled times and temperatures for analysis of the fluids, the receptacles are carried by shuttles which are replaceable and movable within the chemical analyzer and have fluids deposited in them automatically at predetermined times and locations under the control of a program card as they move through temperature-controlled zones at speeds established to keep the receptacles in the temperature-controlled zones long enough to complete a reaction. Two of the shuttles are driven and pull or push the other shuttles in a circular path. In one embodiment, a second circle of shuttles or a reel carrying receptacles moves in the reverse direction from a first group of shuttles so that fluids may be transferred from one receptacle to another at predetermined points to provide greater flexibility in the analyzing apparatus.
