PCT No. PCT/DE96/01771 Sec. 371 Date Apr. 6, 1998 Sec. 102(e) Date Apr. 6, 1998 PCT Filed Sep. 19, 1996 PCT Pub. No. WO97/14035 PCT Pub. Date Apr. 17, 1997The invention relates to a device for determining the dissolution time of medication in pressed form, like tablets and capsules, (especially to DAB 10, 3rd Supplement 1994, or the European Pharmacopoeia or USP [USA]), consisting of a frame (1) with a central column (7) and a base plate (3, 10) having a plurality of holes (5, 5', 11) covered from below by a mesh (4). Test tubes (6, 6') are arranged upright in said holes inside the frame (1). A disk (8, 15) can be movably inserted into said test tubes to weight the individual pressed medication. An electric coil (12) is disposed around each hole (11) and on and/or in the base plate (10), wherein the electric coil forms part of an electrical oscillation circuit (17). A conductor loop (16) is disposed on and/or in the disk (15) for damping the electrical oscillation circuit (17) depending on distance. The electric coil (12) and the conductor loop (16) together are connected to an electric supply and evaluation device (20, 23) to generate oscillations and evaluate the measurement results.
