Automatisches Auflösungsuntersuchungssystem

A dissolution testing system including a base (26); a plurality of vessels (31) mounted on the base; an agitation mechanism (33-35) for agitating a liquid content (32) of the vessels; and a head (38) supported above each of the vessels and operable to automatically inject a liquid media into the vessel. Retained by the control head (38) is a spray wash tube (39) connected to the spray wash line (16), a media fill tube (41) connected to the fill line (19), an aspiration probe (42) connected to the aspirate line (18), a sampling probe (43) connected to the sampling line (17), a pH adjustment and media replacement tube (44) connected to a pH adjustment and media replacement line (45) and a temperature detector (46). Also retained by the control head (38) is an aspiration probe drive mechanism (48), a sample probe drive mechanism (49) (Fig.3), a stepping motor (51) (Fig.4) and an interconnect board (52). Connected to the interconnect board (52) is a cable connector (53) that receives a plug (54) (Fig.5) on the electrical cable (21). The head is covered by a cover (50). A sample tablet dispenser (57) is mounted on the control head (38) and is coupled to the stepping motor (51).
