The apparatus consists of a benchtop case hosting the heating block and a frame supporting the stirring mechanism. The block has a series of jackets for the sample containers: a turntable permits to assemble the sample containers before putting them in the jackets all together. The block can reach temperatures up to 150°C +/- 0.1°C: it is heated by means of a coaxial heater. The stirring device is actuated by means of an electronically piloted gear reduced motor connected to a cam: it is regulated for 25 rpm.
