The invention concerns a rapid-action automatic sampling apparatus comprising an intermittently operable sampling probe which is immersible alternately into a sample-containing vessel and a washing vessel. The probe is arranged on an arm secured to a vertical lifting rod which is journalled both for axial displacement and for rotation about its own axis and which is connected with a crank mechanism, including a swivel arm, for lifting or lowering the rod. There is a further mechanism for rotating the rod between two angular positions: this mechanism is arranged on the rod and its mounting and on the swivel arm. |
