  • Patent number: 10184868
    Abstract: The invention relates to a device and a method for testing tablets. In the process, a tablet is brought onto a rotary disk (1) by a transport rack (6). The rotary disk (1) positions the tablet (7) along one or more positioning surfaces by rotating. The positioning surfaces are preferably an abutment (2) and a stop (3). As soon as the tablet (7) is aligned on a positioning surface, a test of the tablet (7) is carried out by means of a breaking jaw (4). The breaking jaw can test the diameter as well as the breaking resistance of the tablet (7). The transport rack removes the tablet or the tablet debris from the rotary disk (1) after the tablet (7) has been checked.

  • Patent number: 5796016
    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.
