Supply of second-hand three separation horizontal screw centrifugesThe operation method of a horizontal centrifuge: 1. When using a horizontal centrifuge, the centrifuge tube and its contents must be precisely balanced on a balance in advance. The weight difference during balancing must not exceed the range specified in the instructions of each centrifuge. Each centrifuge has its own allowable difference for different rotors, and odd numbered tubes must not be loaded in the rotors. When the rotors are only partially loaded, the tubes must be symmetrically placed in the rotors to evenly distribute the load around them.

2. When centrifuging at a temperature lower than room temperature. The rotary head should be placed in the refrigerator or in the rotary head chamber of the centrifuge for pre cooling before use.

3. During the centrifugation process, it is not allowed to leave at will. The instruments on the centrifuge should be observed at all times to ensure that they are working properly. If there is any abnormal sound, the machine should be stopped immediately for inspection and troubleshooting should be promptly carried out.

4. Each rotor has its own maximum allowable speed and cumulative usage. When using the rotor, please refer to the instruction manual and do not use it at excessive speed. Each rotary head must have a usage record, recording the accumulated usage time. If the maximum usage of the rotary head is exceeded, it must be used at a reduced speed according to regulations.

5. When loading the solution, it is necessary to follow the specific operating instructions of the horizontal screw centrifuge, and select the appropriate centrifuge tube according to the nature and volume of the liquid to be centrifuged. Some centrifuge tubes have no cover, and the liquid should not be loaded too much to prevent it from being thrown out during centrifugation, causing the rotor to be unbalanced, rusted or corroded. For the centrifuge tube of the preparation high-speed centrifuge, it 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 inspected, cleaned and wiped dry in a timely manner. The rotor is a key component that needs to be protected in the centrifuge. When moving it, be careful not to collide to avoid scratches. When the rotor is not used for a long time, it should be coated with a layer of gloss wax for protection. It is strictly prohibited to use centrifuge tubes that are significantly deformed, damaged or aged.
