Now, if we take the test tube and we place it inside a centrifuge, a process known as centrifugation takes place. And centrifugation is this process by which we use angular motion. We basically accelerate our test tube to very high rotational speeds. And what this allows us to do is it basically allows us to separate the different components inside our homogenic mixture based on things like mass, density, size and shape, as we'll see in just a moment. But first, let's actually discuss briefly the physics behind the process of centrifugation. Let's see how it actually works.
