    A magnetic stirrer is a laboratory instrument for liquid mixing, mainly used for stirring or simultaneous heating to stir liquid or solid-liquid mixtures
    of low viscosity.
    Its basic principle is to use the principle of same-sex repulsion and opposite-sex attraction of magnetic fields, and use the magnetic field to push the magnetic stirring bar placed in the container to run in a circular circle, so as to achieve the purpose of
    stirring the liquid.
    With the heating temperature control system, the sample temperature can be heated and controlled according to the specific experimental requirements, and the temperature conditions required by the experimental conditions can be maintained to ensure that the liquid mixture meets the experimental needs
    .
    Precautions 1.
    When stirring, it is found that the stirring bar is jumping or not stirring, please cut off the power supply to check whether the bottom of the beaker is flat and the position is correct, and at the same time, please measure that the current voltage is between 220V ± 10V, otherwise the above situation
    will occur.
    2.
    The heating time should generally not be too long, intermittent use to prolong the life, and do not heat
    when not stirred.
    3.
    Medium speed operation can work continuously for 8 hours, high-speed operation can work continuously for 4 hours, and prevent violent vibration during work
    .
    4.
    Electricity: The power socket should use a three-hole socket and must be properly
    grounded.
    5.
    The instrument should be kept clean and dry, and the solution should not flow into the machine to avoid damage to the machine, and the power should be cut off when it is not working
