ABSTRACT:
An apparatus for selectively injecting a reagent into a reaction chamber from a plurality of reagent reservoirs disposed in a circular configuration includes a separate dispenser mounted on each reagent reservoir. A vertically extending rod having a horizontally extending lever connected thereto is positioned concentrically within the circular array of reservoirs and drive motors are provided for rotating and reciprocating the rod and lever to selectively engage and operate the desired dispenser. Each dispenser is provided with its own distribution tube which directs the reagent in the reservoir directly into a selected reaction chamber, thereby preventing cross contamination of the reagents.
