An arrangement to test the breakdown period and active ingredient release of a test substance comprises at least one heatable testing vessel 1 for the test solution, a mixer and an elevation and control unit. The testing vessel is surrounded by a cladding jacket 3 such that a gap 2 is formed between the jacket and the wall of the testing vessel. At least one heating means being a light-heat source 4, a glass heating element and Peltier element or a ceramic is attached below the testing vessel. In use, air is heated by the heating element and flows through the gap from an inlet 8 to an outlet 9 to heat the testing vessel. Preferably, the cladding jacket is attached to a base element 6 of a housing 16 which holds the light-heat source. Further, a disc 5 may be provided as a cover for the light-heat source wherein the disc is made of ceran or red-coloured glass which shields the visible light, or may be a metal disc. |
