Collector-type magnetic stirrer DF-101S-type collector-type magnetic stirrer DF-101S in DF-101B, based on the increase of high-precision time proportional digital temperature controller and intelligent digital display temperature in two models, arbitrarily set fixed, automatic thermostat, easier to use, intuitive, high precision, reliable standard. This machine has: electric mixer, magnetic stirrer, regulator, heater, temperature controller five functions. Is the chemical laboratory equipment into one of several commonly used. Largely avoided the connection between the devices to each other, the replacement of the trouble, but reduce the number of unsafe factors, greatly improving the work efficiency, cost, effectiveness ratio is very prominent.
