Different Types of Centrifugation Techniques

2022-4-13 · Centrifuges have a speed range that they can achieve, which varies depending on the centrifuge. A low-speed centrifuge may spin at as little as 300 RPM, whereas a high-speed centrifuge may spin at up to 15000 RPM. Ultracentrifuges, the most powerful type of centrifuge, are also available; they can spin at speeds in excess of 150,000 RPM.

Centrifugation: Explanation, Appliions, Sample Questions

2022-4-5 · Centrifugation is the process in which a centrifugal force is applied to separate two mixtures of liquids. In this process, the denser component of the mixture moves away from the shaft and the lighter one towards the shaft. This process is too fast and more time-consuming than churning, so it is used most widely.
