Polarimeter

The waterbath with the most modern comfort and highest safety The
Memmert waterbath is available in six sizes and two performance classes. In addition to the Basic class for simple temperature control tasks, the Excellent version offers precise test procedures with maximum safety: electronic overtemperature protection and a multitude of visual and acoustic signals, e.g. when the filling level is too low, overtemperature, but also for input acknowledgement or at the end of the programme. In the largest water bath model, an optional circulation pump ensures even better thermal homogeneity of the water.
