These compact refrigerated circulators with insulated refrigeration baths are ideal for direct temperature control from −90 up to +200 °C. The low bath volume and high heating and cooling capacity means short heating and cooling rates, which can be increased by using the optional displacement inserts. Optional calibration inserts enable circulators to be used as calibration baths.
