Swinging Bucket vs. Fixed Angle Rotors

Hermle Z206-A紧凑的实验室离心机开放 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.

离心利用中心力将异质溶液的分离驱动到上清液和颗粒中。现代离心机通过以高速旋转溶液的旋转速率来增加重力的力量，以提高沉降速度。在此过程中，具有较高颗粒密度的材料会朝着离心轴（下管下）沉积，而颗粒密度较低的材料会沉积从离心轴远离沉积物。例如，悬浮液中的细菌细胞具有很高的颗粒密度，并且会倾向于底部。

A process that normally takes hours or days under the force of normal gravity (1 g) can be shortened to minutes when a force of 10,000 g is applied with a relatively inexpensive and easy-to-use piece of equipment. The faster the centrifuge turns (i.e., the higher the RPM), the faster the faster the sedimentation. Relative centrifugal force (RCF) is another way of expressing the gravitational force (g-force), or the turning of the rotor, which allows researchers to easily separate tissues, cells, organelles, and macromolecules for further investigation.

离心机结合了两种类型的转子之一，它们容纳了发生分离的管子。固定角转子相对于旋转轴，固定角度的管子以稳定的角度（通常为45°）固定管。当施加中心力时，摆动的桶圆圈摇摆，并将细胞保持大约90°角相对于旋转角度。回想一下，更密集的材料将分开向中心力的角度分开。因此，在摆动的桶转子中，颗粒的材料将在锥体离心管的底部形成，而在固定角度转子中处理的管将在侧面形成沉积物。如果将固体捕获到管的角度，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.
