The PSL Coldfinger CF 15120 is equipped with up to 15 measuring places for multi-place testing. Combining multiple cold fingers in one heating bath facilitates screenings on wax inhibitors, e.g. simultaneous testing of different chemicals on a single sample or testing of different inhibitor concentrations with the same sample. The Cold Finger can be run with separate temperature control and stirring speed for each rack of 5 measuring places, thus reducing full test procedure for a single sample immanently. The dry bath allows a precise temperature control up to +120 °C / +248 °F.
