Intelligence creates the future
Keywords: Rotary Evaporator, Heating and Cooling Circulator, Recirculating Chiller
The heating circulator can realize dynamic temperature control from - 30 ℃ to 200 ℃. It also has the function of heating and refrigeration. The product is efficient and quick, and the liquid filling is simple. The whole liquid circulation is a closed system, without oil mist and water absorption, which ensures the safety of the experiment and the service life of the heat conducting medium. International brand compressor and circulating pump are adopted, with stable performance and reliable quality; The product has self diagnosis function, refrigerator overload protection, high pressure switch, overload relay, thermal protection device and other security functions.
