The magnetic stirrer is easy to operate, stable in performance and small in size, and is suitable for use when the stirring capacity is not large and the solution does not need to be heated.

1. Put the instrument flat, put the container containing the liquid in the middle of the front of the instrument, put an appropriate stirring bar in the container, and make it suck into the center, the container should not be made of ferromagnetic material.
2. Plug in the power supply, turn on the power switch, the power indicator light is on, turn the speed control knob clockwise, the agitator will run from slow to fast, and the speed should not be too fast to prevent the agitator from escaping. If the agitator escapes, it should be turned off and on again. .
3. Note: The power supply needs to be reliably grounded; the solution in the container should not be overfilled, so as not to overflow when stirring.
