ABSTRACT:
A system for eluting a daughter radioisotope from a parent radioisotope and containerizing the resultant eluate in an evacuated container having a rubber stopper, providing for delivery of eluant from a reservoir through a charge of the parent radioisotope in a generator and thence to a tubular needle adapted to be pierced through the stopper of the evacuated container for suctioning the eluant from the sealed eluant supply into the generator and for suctioning the resultant eluate into the container. The needle is at the lower end of a valve body having a valve plug rotatable therein between a closed and open position. The plug is adapted to be pushed down to push the valve body down to cause the needle to pierce the stopper, after which the plug is rotated to open position, in which it effects venting of the eluant reservoir to atmosphere, delivery of eluant from the reservoir to the generator, and delivery of eluate from the generator to the needle.
