Water-thermostattable cell holders are available in single cell or sample changer (linear or carousel) configurations. When connected to a constant-temperature circulating water bath, these cell holders ensure constant sample temperature.

For precise and rapid temperature control, a range of Peltier-effect thermocells is available in single cell or sample changer (linear or carousel) versions. Peltier-effect controllers are useful in applications where an accurate constant temperature or an accurate controlled temperature ramp is required. Optional sample immersion probes are available for accurate monitoring of the true sample temperature.
