Working principle

The magnetic stirrer utilizes the principle of magnetic field and vortex. The container of

the liquid to be stirred submerged in the stirrer is placed on the base of the magnetic stirrer.

When the magnetic stirrer is energized, a rotating magnetic field is generated near the base

to drive the stirrer to circulate in a circle. Movement, and then a vortex is formed in the liquid

in the container, so as to achieve the purpose of stirring the liquid.

method

1. Trial operation: put the mixer in a stable position, plug in the power supply, turn on the power

switch, the power indicator light is on, adjust the knob clockwise, and you can hear the running

sound of the motor in the machine from slow to fast.

2. When using, put the container in the center of the mixer, and put the stirrer in the center,

then start the machine, adjust the knob, select the required stirring speed, and gradually accelerate

or decelerate when adjusting the speed.

Compared with ordinary stirrers, magnetic stirrer has the following advantages:

1. The stirrer is made of PTFE and high-quality magnetic steel, which is resistant to high temperature, wear,

chemical corrosion, and strong magnetism;

2. Fully enclosed heating plate It can be used for auxiliary heatingand can be used for long-term heating;

3. It can be mixed in a closed container, which is ideal and convenient to use;

4. The magnetic stirrer adopts high-quality DC motor, with low noise and stable speed regulation;

5. The stirrer can set the temperature and temperature display, can be used for long-term heating,

and the digital display is intuitive and accurate. Features: The shell is injection-molded by special flame-retardant

reinforced plastic, and the magnetic stirrer has very high resistance to heat, acid, alkali and organic solvents. characteristic.

Magnetic stirrers are widely used for stirring solvents of different viscosities, and the stirring speed and heating temperature

can be continuously adjusted.
