Just letting a suspension sit on the laboratory bench does the same thing: gravity separates the components by density (not weight). That's why you stir paint before you use it: it has partially separated, and has done so without the without the use of a centrifuge.
- samatman 13y agoIt is in fact density, although in my defense I meant molecular weight. But was still wrong ;-) However, there are many suspensions which will never settle under standard gravity, but which will rapidly settle in a centrifuge. We call these colloids.
