Patent number: 9481705Abstract: A modular chemical production system includes multiple modules for performing a chemical reaction, particularly of radiochemical compounds, from a remote location. One embodiment comprises a reaction vessel including a moveable heat source with the position thereof relative to the reaction vessel being controllable from a remote position. Alternatively the heat source may be fixed in location and the reaction vial is moveable into and out of the heat source. The reaction vessel has one or more sealing plugs, the positioning of which in relationship to the reaction vessel is controllable from a remote position. Also the one or more reaction vessel sealing plugs can include one or more conduits there through for delivery of reactants, gases at atmospheric or an elevated pressure, inert gases, drawing a vacuum and removal of reaction end products to and from the reaction vial, the reaction vial with sealing plug in position being operable at elevated pressures.Type: GrantFiled: November 13, 2015Date of Patent: November 1, 2016Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Nagichettiar Satyamurthy, Jorge R. Barrio, Bernard Amarasekera, R. Michael Van Dam, Sebastian Olma, Dirk Williams, Mark Eddings, Clifton Kwang-Fu Shen
