Before using the magnetic stirrer, check if its power supply is connected and if the speed control knob has been reset to zero. The speed control knob must be reset to zero to ensure experimental safety. Place the container containing the solution on the instrument tableMixing position, place the mixer inside, plug in the power plug, turn on the power, and the power indicator light will turn on. Turn on the mixing switch, the indicator light is high, turn the speed control knob clockwise from slow to fast, adjust it to the desired speed, and use the mixerDrive the solution to rotate and homogenize.

The machine is equipped with a heating device. Heating is required. Insert the sensor plug into the back of the instrument and adjust the temperature control knob to the desired temperature. If heating is not required, adjust the temperature knob to zero and unplug the sensor plug.

If the heating temperature is above 70C, the continuous heating time should not exceed 2 hours. If the heating temperature exceeds 80C, the upper opening of the container should be covered. After stirring the solution thoroughly (the solution is transparent and clear), first turn the speed control knob counterclockwiseAdjust the direction from fast to slow to zero. If using the heating function, adjust the temperature control knob to zero, then turn off the power switch, and finally remove the dispenser containing the solution. Clean the magnetic stirrer and its surrounding environment.
