Immersion and bridge thermostats can be combined with variable bath sizes/depths. Thanks to their extendable telescope bridges, bridge thermostats can be adapted to bath vessels with a length of 550 mm.  With the different pump models, immersion depths and heating outputs, baths with larger volumes or baths with greater immersion depths can be circulated and their temperature controlled easily, and this with a temperature stability of up to +-0.01 K. Immersion and bridge thermostats can also be used to control the temperature of external systems.
