Circulating thermostats

A.KRÜSS offers two thermoelectric circulation thermostats with integrated Peltier technology for external temperature control. The temperature is generated by means of a current flow through semiconductors. So can be done by simply reversing the direction of flow in a small space both heating and cooling. The A.KRÜSS circulating thermostats fulfill all standard tasks and routine work in laboratories and industry. They are specially designed for sample temperature control, analysis tasks and for the temperature control of our high-quality laboratory equipment such as polarimeters and refractometers.
