1. Stable operation: Before starting the centrifuge, check whether it is stable and gradually adjust the speed gear, while observing the operating status of the centrifuge. After reaching the standard operating speed, the sample can be centrifuged.
2. Centrifugal speed selection: The selection of centrifugal speed should take into account factors such as the number of samples, the loading capacity of the centrifuge tube, and the density of the centrifugal agent. High or low centrifugal speed can cause differences or adverse effects on experimental results, so it is necessary to make reasonable choices according to the specific requirements of the experiment.
3. Centrifuge time: The centrifugation time must also be determined according to different experimental requirements, and can generally be comprehensively evaluated based on factors such as the density and use of the centrifugal agent. Both too short and too long centrifugation times may affect the stratification effect of the sample, which is not conducive to the accuracy and reliability of the experiment.
4. Monitoring the experimental process: Timely monitoring and adjustment are necessary for factors such as temperature and centrifugal force that may occur during the operation of the centrifuge. The experimental site should be kept clean to avoid unnecessary interference and error effects.
5. Shutdown and sample removal: After the experiment is completed, the centrifuge must be stopped and the speed must be reduced to 雩 before opening the centrifuge door and slowly removing the balanced centrifuge tube. Be very careful during operation to ensure the loading of the centrifuge tube, deformation and movement of the centrifuge tube and the centrifugal rotation axis.
