Centrifugal separation technology has also undergone several generations of replacement, from medical centrifuges, low-speed refrigerated centrifuges, high-speed centrifuges to high-speed refrigerated centrifuges, ultra-large capacity refrigerated centrifuges, ultra-centrifuges, ultra-refrigerated centrifuges, and intelligent high-speed refrigerated centrifuges.

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

Answer: The centrifuge is generally placed in a dry place away from direct sunlight. The heat dissipation capacity of the centrifuge is relatively large. Do not stack debris around it. Keep it at least 10cm away from the walls and baffles such as airtight and poor heat dissipation. At the same time, the centrifuge should be placed in a separate room as much as possible. Never place organic reagents and flammable materials around.

Question 2: What maintenance should the centrifuge take care of to prolong its life?

Answer: After each use, you must open the centrifuge lid to allow the heat or water vapor to evaporate naturally. If you used low temperature centrifugation before, there may be ice, you must wait for the ice to melt, and wipe it with a dry cotton gauze in time. Close the lid when there is no obvious water vapor. If the centrifuge rotor can be replaced, take out each rotor in time after use, scrub it with a clean, dry medical gauze, and place it upside down. Never use a sharp knife to scrape. The aluminum rotor should be cleaned more often. At the same time, the centrifuge should not be maintained and repaired frequently. The operator should cut off the power when leaving. The first-time user should consult a person who has used it before or refer to the instruction manual, and do not use it blindly.

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

A: When we use it, we must pay attention to it from all aspects. After selecting the rotor and setting the parameters, observe the centrifuge for a while, and wait for the maximum speed and stable operation before leaving. If you hear abnormal sound or smell during operation, you should take the brake immediately, press the "Stop" button, and cut off the power if necessary. Centrifuge tubes must be placed symmetrically, and the corresponding centrifuge tubes should be as equal as possible. During the operation of the instrument, it is absolutely forbidden to open the centrifuge lid! At the same time, it is necessary for all laboratory personnel to develop good registration habits. The first one can know who used it before and the condition of the instrument when it was used before; the second one can know the number of times the centrifuge has been used. To know if it needs to be repaired or replaced.

Question 4: What are the common accidents of centrifuges?

Answer: Due to the high frequency of use of the centrifuge, the machine is damaged and the frequency of accidents is high. The main reason is caused by improper operation of the experimental staff. Not working, the more serious problems include uneven bending of the rotating shaft, motor burnout, horizontal bucket throwing out, more serious accidents and even injury.
