  • Patent number: 10134496
    Abstract: Methods and devices for directing a waste fluid from a radiopharmaceutical synthesis system to a waste vessel are provided. In one example, the method includes serially connecting a primary waste vessel to a secondary waste vessel with a fluid conduit, including a waste valve connected to the fluid conduit extending between the primary waste vessel and secondary waste vessel; opening the waste valve so as to allow fluid communication between cavities of the primary and secondary waste vessels; drawing a low pressure in both waste vessels; closing the waste valve so as to fluidically isolate the secondary waste vessel from the primary waste vessel, discharging the waste fluid through a pump valve into the primary waste vessel, and opening the waste valve to evacuate the waste fluid from the primary waste vessel into the secondary waste vessel.
