The three-legged centrifuge is a kind of centrifugal equipment commonly used in the laboratory, which separates the mixed liquid by centrifugal force generated by high-speed rotation. In the process of using the centrifuge, the correct operation method and safety awareness are very important. Here we will introduce three points of attention, let you in the operation of the three-foot centrifuge more secure.

1. Select the appropriate centrifuge tube and rotor
When using a three-foot centrifuge, you must first select the appropriate centrifuge tube and rotor. The centrifuge tube should be able to withstand the centrifugal force generated during high-speed rotation, so pay attention to its maximum speed and maximum relative centrifugal force when choosing a centrifuge tube. The rotor needs to be selected according to the type and specification of the centrifuge tube, to ensure that the rotor and the centrifuge tube can be completely matched, to avoid the mismatch caused by the centrifuge imbalance or other security risks.

2. Equilibrium sample loading and avoidance of overspeed
During sample centrifugation, ensure balanced sample loading in the centrifuge. The samples should be evenly distributed in the holes of the rotor and balanced with each other.

in setting the speed of the centrifuge, we should pay attention to the maximum speed of the centrifuge and the maximum relative centrifugal force of the sample, to avoid overspeed and produce excessive centrifugal force, resulting in the imbalance of the centrifuge or other security risks.

3. Pay attention to the balance and stability of the centrifuge
Before starting the centrifuge, check the balance and stability of the centrifuge. First, put the unloaded rotor into the centrifuge for trial rotation to observe whether there is abnormal vibration or noise. If there is no abnormality, centrifuge the sample again.

During the operation of the centrifuge, it is necessary to avoid sudden shutdown or rapid speed change, so as not to cause the centrifuge to be unbalanced or other unexpected situations. It is very important for

to use the tripod centrifuge correctly. Only in strict compliance with the operating procedures and precautions, in order to ensure the safe operation of the centrifuge, both to protect personal safety, but also to protect the integrity of laboratory equipment. I hope everyone can strictly follow these precautions when using centrifuges to ensure the safety and stability of the laboratory.
