Abstract
An apparatus (1) for dissolution testing comprises a tank (2) having a circular cylindrical outer body portion (21) with a transparent side wall and a circular cylindrical inner body portion (22) with a transparent side wall, wherein the inner body portion (22) is coaxially arranged with respect to the outer body portion (21) such that an outer interior (23) having a ring-shaped cross section is defined between the outer body portion (21) and the inner body portion (22) and an inner interior (24) having a circular cross section is defined inside the inner body portion. The apparatus (1) further comprises a plurality of dissolution vessels (4) arranged in the outer interior (23) of the tank and a heater assembly being arranged to heat a test media in the vessels (4) to a predefined temperature. The apparatus (1) according to the invention allows for a comparably precise monitoring of vessels (4) inside the tank (2) and/or an appropriate manipulation of the vessels (4) inside the tank (2).
