Arrangement for testing of the disintegration time and the active substance release of test specimens in liquids

摘要

The invention relates to an arrangement for testing the disintegration time and the active substance release of a testpiece with at least one heatable test vessel for the test solution, a stirrer and - an evaluation and control unit, wherein the test vessel is surrounded with a casing body so that, between the wall of the casing and the wall of the test vessel an intermediate space is formed below the test vessel at least one light - heat source or a glass - heating element is arranged and for the by means of the light - heat source or of the glass - heating element is to be heated air which flows through the interspace, inlet and outlet openings are provided.With the present invention combines the advantage that an elegant, trouble-free and low-maintenance technical solution is provided, which a visual check of the test vessel and thus of the additive of the test specimen is made possible and which can be made inexpensively. This makes possible a from the source of the heat immediately separate contactless heating of the test solution. In addition, it is connected with low energy costs.
