摘要

Arrangement for testing of the disintegration time and the active substance release of a testpiece with at least one heatable test vessel (1) for the test solution with a casing body (3) is surrounded in such a way that, between the wall of the casing (3) and the wall of the test vessel (1) an intermediate space (2) is formed, through which heated air can flow out, a stirrer and - an evaluation and control unit, characterised in that below the test vessel (1) at least one light - heat source (4) or a glass - heating element is arranged, for the through the intermediate space (2) flowing heated air inlet openings (8) and outlet openings (9) are provided, below the test vessel (1) an axis (10) is disposed vertically, which with its upper end by a disk (5) extends between the test vessel (1) and the light - heat source (4) is arranged and which, on its upper end, a sensor (7), of which the positioning of the test vessel (1) and the detected with the evaluation - and control unit is connected.
