ABSTRACT:
A dissolution tester has a plurality of test vessels for receiving dissolution samples and a plurality of stirring elements for stirring the dissolution samples, the stirring elements being disposed in a vertically adjustable housing. A discharging device is provided having discharging tubes for discharging predetermined volume fractions of the dissolution samples to the test vessels. The discharging tubes are disposed at a predetermined working position in the test vessels in accordance with the filling level of the dissolution sample and the stirring element used. The discharging tubes are disposed on a frame and the frame is disposed on the housing in vertically adjustable manner. A stepping motor moves the frame and thus the discharging tubes to the particular working position in program-controlled fashion in accordance with the input data on the filling level and the stirring element. A computing device stores the measurement data and predetermined parameters.
