Abstract
A system, apparatus, and method for transferring chemical solutions and synthesizing a tracer. For transferring chemical solutions, the system comprises a primary container; a secondary container; a first line in communication with the primary container and the secondary container. The first line facilitates the flow of gas and/or liquid between the primary container and the secondary container. A valve located upstream of the secondary container and downstream of the primary container regulates flow within the first line; a second line in communication with the secondary container. For synthesizing a tracer, the system includes a source of a solution having a radionuclide. A first container has a tracer precursor and is in communication with the source of solution.
