Keywords: Rotary Evaporator, Heating and Cooling Circulator, Recirculating Chiller
The high and low temperature integrated chiller is a new type of laboratory temperature control equipment, which has the functions of heating and cooling at the same time, and can realize the continuous temperature control of - 80 ℃ ~ 300 ℃ by the same medium, eliminating the tedious steps of changing the medium. The whole circulation system is completely closed, so there will be no oil mist at high temperature, and the water vapor in the air will not be absorbed at low temperature, so the efficiency of refrigeration and heating becomes higher.
