Some common problems and solutions for medical centrifuges

Question 1: What should I pay attention to when placing the centrifuge?

A: The centrifuge is usually placed in a dry place away from direct sunlight. Centrifuge heat dissipation is relatively large, do not pile up debris around, surrounded by walls, baffles and other items that are not airtight, poor heat dissipation, at least 10cm. At the same time, the centrifuge should be placed in a room as far as possible, and no organic reagents or flammable materials should be placed around.

Question 2: What maintenance should the centrifuge pay attention to, which can extend the life?

A: After each use, the centrifuge cover should be opened to allow the heat or moisture to evaporate naturally. If you have used low temperature centrifugation before, there may be ice. If the ice melts, wipe it with dry cotton gauze. Then cover the cover when there is no obvious water vapor. If the centrifuge rotor can be replaced, each rotor should be removed in time after use, cleaned with a clean, dry medical gauze, and placed under the buckle. Do not use a sharp scraper. The aluminum rotor should be cleaned frequently, and the centrifuge should not be maintained and repaired frequently. The operator should cut off the power when leaving. For the first time users, please consult the personnel who have used it before or refer to the instruction manual. Do not use it blindly.

Question 3: What should we pay attention to when doing specific operations?

A: When we use it, we must pay attention to it from all aspects. After selecting the rotor and setting the parameters, it is necessary to observe the centrifuge for a while, and then reach the maximum speed and run stably before leaving. If you hear abnormal sounds or smell any smell during operation, you should immediately take the brakes, press the “Stop” button, and turn off the power if necessary. The centrifuge tubes must be placed symmetrically, and the corresponding centrifuge tubes should be as equal as possible. It is absolutely forbidden to open the centrifuge cover during the operation of the instrument! It is also necessary to develop good registration habits for all personnel in the laboratory. The first one can know who used it before, the condition of the instrument before use; the second can know the number of times the centrifuge is used. To know if it needs to be repaired or replaced.

Question 4: What are the common accidents in centrifuges?

Answer: Because the frequency of use of the centrifuge is high, the machine has damage and the frequency of the accident is high. The main reason is caused by improper operation of the experimenter. Common problems are: the cover cannot be opened, the centrifuge tube cannot be taken out, and the centrifuge button is pressed. Not working, the more serious problem is that the uneven rotation of the shaft causes the bending, the motor burns out, the horizontal bucket is thrown out, the more serious accidents even hurt people and so on.
