    What are the precautions for the use of floor centrifuges? Floor-standing centrifuge is one of many types of centrifuges.
    It is also called vertical centrifuge.
    Its application range is also relatively wide, such as laboratory, scientific research, industry and other fields
    .

    But no matter what kind of place it is used in, the matters to be paid attention to are the same
    .

    Let's take a look at what matters should be paid attention to in the use of vertical centrifuges
    .

    1.
    The main power plug should be removed when the equipment is not used for a long time or repaired
    .

    If the main power plug is not removed, the instrument is still powered
    .

    2.
    It is forbidden to operate the rotor with large weighing deviation and unbalanced operation
    .

    3.
    It is forbidden to operate beyond the high speed set by the rotor, otherwise it is prone to vicious accidents
    .

    4.
    If there are cracks in the rotor body or the hanging cup, it is forbidden to use it, otherwise there will be a burst safety accident
    .

    Unbalanced rotor (blood bag, vial or tube balance difference, asymmetric placement of separated samples) is prohibited
    .

    5.
    The rotor should be properly installed on the rotor seat to ensure that the transfer pins are meshed with each other, and the transfer pins in the rotor core holes are inserted into the gaps of the transfer pins of the rotor seat to ensure the rotor falls
    .

    Before use, carefully observe the rotor and test cup for cracks and rust marks, and prohibit the use of cracked or rusted rotors
    .

    6.
    When the centrifuge is running, it is forbidden to open the door of the centrifuge chamber
    .

    7.
    It is forbidden to use the centrifuge without debugging the level
    .

    8.
    Check whether the external power supply meets the standard
    .

    9.
    It is forbidden to change the parameters of the inverter
    .

    10.
    Select the corresponding rotor and centrifuge tube according to the sample requirements
    .

    The rotor is prohibited from rotating higher than the specified high speed
    .

    If stainless steel centrifuge tubes are used, the set speed should be reduced to below 80% of the high speed
    .

    to ensure safe use
    .

    If the specific gravity of the solution is higher than 1.
    2, the allowable high speed should be reconfirmed as follows
    .

    N=n(1.
    2/S) In the formula: N----the newly confirmed permitted high speed n----the originally specified high speed S----the specific gravity of the solution to be separated Eleven, centrifuge tube or centrifuge bag After loading the sample, balance it with a double-disc balance, the difference should not exceed 0.
    5 g, and then put it into the rotor symmetrically, and cover the door
    .

    Centrifuge tubes should be renewed on time, and centrifuge tubes that are about to burst should not be used
    .

    The above is the relevant introduction about the key points of the use of the floor-standing centrifuge.
    I believe that everyone has a corresponding understanding of this after reading, and I hope it will be helpful to everyone
    .
