1. When using various centrifuges, the centrifuge tube and its contents must be precisely balanced on the balance in advance. The weight difference during balance shall not exceed the range specified in the manual of each centrifuge. Each centrifuge has different rotors. For their respective allowable differences, the rotor must not be loaded with an odd number of tubes. When the rotor is only partially loaded, the tubes must be placed symmetrically in the rotor so that the load is evenly distributed around the rotor.
2. When centrifuging at a temperature lower than room temperature. The rotor should be pre-cooled in the refrigerator or in the rotor room of the centrifuge before use.
3. Do not leave at will during the centrifugation process, and observe whether the instrument on the centrifuge is working properly at any time. If there is any abnormal sound, stop the machine for inspection immediately and troubleshoot in time.
4. Each rotor has its maximum allowable speed and cumulative usage limit. When using the rotor, please refer to the manual and do not use it at excessive speed. Each rotor must have a use file to record the cumulative use time. If the rotor's maximum use limit is exceeded, it must be used at a reduced speed according to the regulations.
5. When loading the solution, proceed according to the specific operating instructions of various centrifuges, and select suitable centrifuge tubes according to the nature and volume of the liquid to be centrifuged. Some centrifuge tubes have no caps, and the liquid should not be packed too much to prevent centrifugation. Throwing out will cause the rotor to be unbalanced, rusty or corroded. The centrifuge tube of a preparative ultracentrifuge is often required to be filled with liquid to prevent the upper part of the plastic centrifuge tube from sinking and deforming during centrifugation. After each use, the rotor must be carefully checked, cleaned and wiped dry in time. The rotor is a key part of the centrifuge that must be protected. Be careful when moving it, and avoid collisions to avoid scars. When the rotor is not used for a long time, you must Coated with a layer of glazing wax for protection. It is strictly forbidden to use centrifuge tubes that are significantly deformed, damaged or aging.
