ABSTRACT:
A disintegration testing device for detecting the disintegration behavior of solid particles, in particular tablets, in a liquid, which comprises a supporting or holding device including a carrier which is movable in the upward and downward directions for supporting a vessel containing solid particles, a liquid bath into which the vessel can be submerged, a first lifting device which during normal operation moves the carrier and thus the vessel in the liquid in the upward and downward directions, and a second lifting device elevating the vessel from the liquid upon termination of one testing operation. The first lifting device includes a lifting arm which is driven by a motor through a drive shaft and a first roller disposed at a given distance spaced therefrom and supporting the supporting device. The second lifting device includes a second roller which is slidably movable out of the lifting arm and disposed at a greater radial distance from the driving shaft and supporting the supporting device upon it having been pushed in the outward direction for carrying out a larger stroke.
