What should be paid attention to when using centrifuge and how to maintain it

matters needing attention:

1: What are the common troubles of centrifuges?

Because of the high frequency of using centrifuge, the main cause of machine damage and frequent incidents is improper operation of laboratory personnel. Common problems include: the cover can not be opened, the centrifugal tube can not be taken out, the centrifugal button does not work, and the more serious problem is that the shaft is under uneven stress, leading to twists and turns, motor burning, horizontal bucket pop-up, and even more serious incidents. Injuries and so on.

2: What should be paid attention to in the specific operation?

Pay attention to all aspects when using. Select the machine head, set the parameters, observe the centrifuge for a period of time, and when the centrifuge reaches the maximum speed and stable operation, it will be detached. If there is abnormal noise or odor during operation, brake immediately, press the "stop" button, and cut off the power supply if necessary. It is necessary to place the centrifugal tubes symmetrically, and the corresponding tubes should have the same weight as far as possible. In the process of equipment operation, absolutely stop opening the centrifuge cover! Together, all laboratory personnel should develop outstanding registration habits. First of all, we can know who has used it and the state of the equipment. Secondly, we can know how many times the centrifuge has been used and whether it needs to be repaired or replaced.

3: Centrifuges are generally placed in a dry place away from direct sunlight. The heat dissipation of the centrifuge is large, and no debris should be accumulated around the centrifuge. The distance from the wall, baffle and other airtight and poor heat dissipation articles shall not be less than 10cm. At the same time, the centrifuge should be placed in a separate room as far as possible, and organic reagents and inflammables should not be placed around.

4: In order to extend the service life of centrifuge, what maintenance should be paid attention to?
After each use, the centrifuge cover should be opened to allow the heat or steam to evaporate naturally. If you've used cryogenic centrifugation before, there may be ice. Wipe the dry gauze in time, when it is not covered with ice. If the centrifuge head can be replaced, it should be taken out in time after use, cleaned with clean and dry medical gauze, and placed upside down. Don't scratch with sharp objects. The aluminum rotor should be cleaned frequently, and the centrifuge should not be regularly protected and maintained. Cut off the power supply when the operator leaves. The initial user should consult the person who has used it or refer to the instruction manual. Don't use it blindly.
