The present invention provides EWOD devices, reactant delivery systems, and methods for preparing radioactive compounds using these devices and delivery systems. A first substrate having one or more fluid paths includes a number of individual electrically conductive electrode pads spaced from and insulated from the fluid paths. The conductive pads are separated from each other by a non-conductive space and have electrically conductive lines attached thereto, each conductive line 52 being provided to send an electrical signal to the conductive pad, A conductive line is attached to the conductive pad to provide an electrically directed movement of fluid droplets along the fluid path, a first substrate, one or more fluid delivery sites, and a first One or more reaction sites or heater sites 44 positioned along the fluid path on the substrate, the fluid path from one or more fluid delivery points to one or more reaction sites or heating In the organ part That.
