    Introduction to the adjustment method of the water bath constant temperature oscillator The water bath constant temperature oscillator is a biochemical instrument that combines a temperature-controlled constant temperature water bath and an oscillator.
    Preparation of indispensable laboratory equipment
    .

    The water bath constant temperature oscillator is a biochemical instrument that combines a temperature-controlled constant temperature water bath and an oscillator.
    Shaking culture of liquid and solid compounds
    .

    Before the initial use, the water bath constant temperature oscillator should first check the thermostat power plug with a multimeter for a safety check, use one stop of the measuring resistance, and measure whether there is a short circuit or poor insulation between the upper phase, middle and ground of the plug; Add distilled water as required, connect the power plug to the power supply, turn on the power switch on the control box and the electric pump switch to make the water in the tank circulate and convect; adjust the constant temperature water bath to the set temperature
    .

    Assuming that the room temperature is 20°C and the experimental temperature is to be set to 25°C, the adjustment method of the water bath constant temperature oscillator is as follows: first unscrew the locking screw of the screw adjusting cap on the upper end of the mercury contact thermometer, and then turn the magnetic screw adjusting cap to make the temperature indicating nut When the temperature is about 2~3°C lower than the experimental temperature to be set, turn on the heater switch to heat.
    If the water temperature of the water bath constant temperature oscillator is quite different from the set temperature, it can be heated with high power first.
    When the water temperature of the constant temperature water tank is close to the set temperature , switch to low-power heating
    .

    Watch the reading of the thermometer, when it reaches about 23°C, turn the magnetic screw adjustment cap again, so that the contact and the mercury column are just on and off
    .

    At this point, heat slowly until the temperature reaches 25°C, and then tighten the locking screw
    .

       1.
    After the instrument has been used for a long time, natural wear and tear is a normal phenomenon
    .

    After using the water bath constant temperature oscillator for one year, if it is found that the motor has abnormal noise, the heating system is abnormal, the bearing of the transmission part is worn, the belt is loose or cracked, the heating constant temperature is abnormal, the electronic control element is missing, etc.
    Services will continue to be provided to assist in processing
    .

       2.
    Correctly use and pay attention to the maintenance of the instrument to keep it in good working condition and prolong the service life of the instrument
    .

       3.
    During the continuous operation of the water bath constant temperature oscillator, regular inspections should be made every three months: check whether water droplets, dirt, etc.
    fall on the motor and control components; check the water quality and cleanliness in the water tank; check the fuse, control components and fastening screws
    .

       4.
    The bearing of the transmission part of the water bath constant temperature oscillator has been filled with an appropriate amount of grease before leaving the factory.
    During the continuous operation of the instrument, the grease should be filled every six months, and the filling amount accounts for about 1/3 of the bearing space
    .

       The above is the relevant introduction about the adjustment method of the water bath constant temperature oscillator.
    I believe that everyone has a corresponding understanding of this after reading, and everyone can use it as a reference.
    I hope it will be helpful to you
