These apparatus are intended for solutions of low viscosity in open or closed vessels. Stiring is accomplished by a magnetised tefflon coated paddle to be placed in the container. Each appratus of operated on a bench (Table), a stand or a laboratory scaffold as well. The intessity of stirring, depending on requirements, can be adjusted with the voltage controller incorporated which also ensures adjustments from vey low to the maximum agitation. But have additional Hot Plate to achive heating of solutions to be stirred. The heating is controlled by three heat controlled/energy regulator which ensures regulation at any desired percentage of the capacity of heater. 220/230 volts AC, 50 Hz.
