摆动铲斗与固定角度转子
当使用相对便宜且易于使用的设备时，通常需要缩短正常重力（1g）的力（1g）的时间或几天的过程。离心机转弯的速度越快（即，rpm越高），沉降越快越快。相对离心力（RCF）是表达重力（G-力）的另一种方式，或转子的转动，其允许研究人员容易地分离组织，细胞，细胞器和大分子以进一步调查。

摆动铲斗与固定角度转子
Researchers in biochemistry, molecular biology, medicine and other fields commonly use centrifugation to separate sample components, a technology that relies on gravity and mass: particles in a heterogeneous solution will over time separate based on size and density. Smaller, less-dense particles may also migrate downward, but at a much slower rate; some particles will never settle, but remain suspended in solution. Because centrifuges accelerate and enhance this process, they have found widespread use across the sciences since the late 19th century.
离心利用离心力使异质溶液分离成上清液和颗粒。现代离心机通过以高速速率纺丝溶液来增加重力的力，以增加沉淀率。在此过程中，具有高粒子密度的材料将朝向离心轴（向下管）沉积物，而具有较低粒子密度的材料将从离心轴沉积。例如，悬浮液中的细菌细胞具有高颗粒密度，并且倾向于沉降到底部。
当使用相对便宜且易于使用的设备时，通常需要缩短正常重力（1g）的力（1g）的时间或几天的过程。离心机转弯的速度越快（即，rpm越高），沉降越快越快。相对离心力（RCF）是表达重力（G-力）的另一种方式，或转子的转动，其允许研究人员容易地分离组织，细胞，细胞器和大分子以进一步调查。
离心机采用两种类型的转子之一，其中发生分离的管。固定角转子相对于旋转轴线以稳定角度（通常为45°）的管子保持管。当施加离心力并相对于旋转角度将近似90°角保持细胞时，摆动铲斗转子摇摆。回想一下，更致密的材料将分离为向心力的角度。因此，在摆动铲斗转子中，粒状材料将在锥形离心管的底部形成，而在固定角转子中处理的管将形成侧面的沉降。如果固体陷入管的角度，这可能是有问题的。
The fact that swinging-bucket rotors offer a superior sedimentation location makes them the obvious choice for centrifuging samples under most conditions; however, fixed-angle rotors offer valuable benefits that often make them a more desirable choice. What are they? First, due to its simple and efficient tube spacing, a fixed-angle rotor can hold a greater quantity of tubes compared to its swinging-bucket counterpart, making it more practical for high-throughput applications. Next, as a result of the rigid design of the metal alloy material, fixed rotors can withstand much higher gravitational forces necessary when separating biological macromolecules such as RNA, DNA and protein. Finally, researchers often wish to wash the pelleted material repeatedly after centrifugation. The placement of the pellet on the side of the tube allows it to be washed with solution more easily without the possibility of disturbing the pellet.
