ABSTRACT:
A generator of radionuclides such as technetium-99m comprises a generator column (10) containing the radionuclide, a first reservoir (16) for eluent, a second reservoir (18) to contain a volume of the eluent required for a single elution, and a vessel 40 to contain eluate. First, a pre-set volume of eluent is transferred from the first to the second reservoir; then the eluent is sucked from the second reservoir through the column into the eluate vessel. A hydrophobic filter 32 adjacent the second reservoir (18) permits the use of air to dry the column (10) and to bring the partly filled eluate vessel (40) to atmospheric pressure.
