Abstract: Apparatus and method for producing a radiopharmaceutical formulation utilize a radiation-shielding container for receiving a vial having the non-radioactive components necessary to form a radiopharmaceutical formulation therein. A mixture of such non-radioactive components and a radioactive liquid added thereto is both heated and cooled using a thermoelectric element. The container comprises a hollow outer shielding member formed from a radiation shielding material and a vial holder formed from a highly heat conductive material received therewithin. The vial holder includes a skirt portion that defines a socket. The socket is sized to receive in an intimate heat transmissive relationship a mounting projection that is itself connected in thermally conductive contact with the thermoelectric element.
