Question 1: What should be noted when placing centrifuges?

Answer: Centrifuges are usually placed in a dry place away from direct sunlight. The centrifuge has a relatively large heat dissipation capacity. Do not stack debris around it, and keep it at least 10cm away from walls, baffles, and other objects that are not breathable and have poor heat dissipation. Meanwhile, try to place the centrifuge separately in a room and avoid placing organic reagents or flammable materials around it.

Question 2: What maintenance should be paid attention to for centrifuges?

Answer: After each use, the centrifuge cover should be opened to allow the heat or water vapor to evaporate naturally. If low-temperature centrifugation was used before and there may be ice formation, wait for the ice to melt and clean it with dry cotton cloth in a timely manner. When there is no obvious water vapor, cover the lid. If the centrifuge rotor can be replaced, each rotor should be removed promptly after use, cleaned with clean, dry medical gauze, and placed upside down. Do not use sharp tools to scrape. Aluminum rotors should be cleaned regularly, and centrifuges should be maintained and inspected regularly. Operators should cut off the power when leaving. First time users should consult with personnel who have used it before or refer to the instruction manual as the main reference, and should not use it blindly.

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

Answer: We need to pay attention to various aspects when using it. After selecting the rotor and setting the parameters, observe the centrifuge for a while until it reaches high speed and runs stably before leaving. If you hear any abnormal sound or smell any odor during operation, you should immediately apply the brakes, press the "stop" button, and if necessary, cut off the power. The centrifuge tubes must be placed symmetrically, and the corresponding centrifuge tubes should have equal weights as much as possible. During the operation of the instrument, it is forbidden to open the centrifuge cover. At the same time, it is necessary for all laboratory personnel to develop good registration habits, so as to know who has used it before and the condition of the instrument when it was used before; The second way is to know the number of times the centrifuge has been used, in order to determine whether maintenance or replacement is needed.

Question 4: What are the common accidents of centrifuges?

Answer: Due to the high frequency of use of centrifuges, there is a high frequency of machine damage and accidents, mainly caused by improper operation by laboratory personnel. Common problems include: the lid cannot be opened, the centrifuge tube cannot be removed, the centrifuge button does not work, and more serious problems include uneven force on the shaft causing bending, motor burnout, horizontal bucket throwing, and even more serious accidents causing injury. Correct operation and reasonable maintenance are the key to ensuring the normal operation of instruments and extending their service life. Centrifuges with high performance must be operated correctly and maintained regularly. By observing the operating status, listening to sounds, regularly diagnosing, and promptly addressing issues, we can reduce the failure rate, extend the service life, and maximize the efficiency of the centrifuge.
