Laboratory Reactoris equipped with annular rare-earth magnetic coupling driver. It has big force moment, and is well sealed. The heating part which is in the bottom of the reactor case is made of 1Cr18NI9Ti stainless steel. Heating mode is electric heating and heat transfer oil heating, both of which have brilliant heating effect. The stirring bearing has a pipe box which is tough and self-lubricating. The agitating valve is the pushing type which can scatter the medium evenly and is suitable to stir media of many kinds. The accurate PID auto-controlled temperature controller is used in the heating control system, and it can control the temperature freely. This series product has the characteristics of low noise, smoothness of operation and simplified operation, and it is the ideal reaction vessel for various chemical reaction in lab.
