ABSTRACT:
For the radiation-proof elution and metering of a radioactive nuclide from a nuclide generator into a stock ampoule, the generator located in a radiation-proof housing is connected, on the one hand, to a stock of liquid nuclide solvent and, on the other hand, to an aspiration and metering device, connected to a filling mechanism, for the eluate. The generator is then flushed through under program control with a predeterminable quantity of solvent and the eluate is transferred into an intermediate vessel of the aspiration device, whereupon a predetermined quantity of eluate is discharged by means of the metering device into the filling mechanism, in which this quantity is filled into a pierceable ampoule; the intermediate vessel, the aspiration and metering device and the filling mechanism are also accommodated in the radiation-proof housing, and the closure of the pierceable ampoule is moved into alignment with an orifice of the housing, through which orifice the particular quantity of eluate is taken out of the pierceable ampoule from outside the housing.
