An apparatus for controlling the removal of one or more phases from a liq-liquid extractor having a mixer and a settler for light and heavy phases. The apparatus has a riser tube for the removal of one or more of the heavier phases having one end connected to an opening in the wall of the settler adjacent to a heavier phase and the other end open at a height of a light phase in the settler and a gas intake tube having one end connected to a gas source and its opposite end connected to the riser tube. The control apparatus of the instant invention is particularly suitable for the treatment of organic solvent wastes from radioactive systems.

Apparatus for the controllable removal of one or more phases from a

Apparatus for taking samples of toxic and/or radioactive liquid substances y introducing such substances into sample vessels, the apparatus including a holder for holding such a vessel, at least one needle head filling system composed of upwardly pointing hollow needles for introducing a sample of one such substance into such a vessel at a filling position, and inlet and outlet conduits for pneumatically conveying vessels to or from the holder at a transfer position, with the holder being composed of a turntable having a sleeve for accommodating such vessel and mounted to undergo rotary movement to convey a sample vessel held in the sleeve between the filling and transfer positions, and with the apparatus further including a stand supporting the filling system below the holder, and a lifting device connected for imparting a translational movement to the holder to bring a vessel in the holder to operative association with the filling system, the lifting device being arranged such that the translational movement which it produces is independent of the rotary movement of the turntable.
