Claim:
1. An article of laboratory glassware for directing the flow of chemical materials, the article comprising: a glass manifold having a plurality of first ports and at least one second port and a plurality of stopcock housings, each stopcock housing having an inlet port and an outlet port for carrying the flow of and controlling the flow of chemical materials, wherein one of the ports of each of the stopcock is connected to one of the manifold first ports; a plurality of rotating plugs, each rotating plug associated with a particular stopcock housing and rotationally fitted into the associated stopcock housing, wherein the rotation of each rotating plug is driven by the rotational output of an associated planetary gear arrangement; a plurality of electrically-operated motors, each electrically-operated motor associated with a particular rotating plug, its associated stopcock housing, and the corresponding associated planetary gear arrangement, wherein the rotation input of the corresponding associated planetary gear arrangement is driven by an associated electrically-operated motor, wherein each of the rotating plugs comprises a first elongated opening and a second elongated opening connected by a passageway through the rotating plug thereby connecting the inlet port with the outlet port of each stopcock, and further wherein the first and the second elongated openings define an area for carrying the flow of chemical materials, and wherein each of the at least one output ports of the manifold is terminated to a ground glass joint.
