[0003] When using the centrifuge, first, the upper cover of the centrifuge is tightly covered, and then the solid-liquid mixed liquid is introduced into the centrifuge. The centrifuge generates centrifugal force by rotation, so that the solid and liquid are separated. At this time, the liquid forms a liquid surface under the action of centrifugal force.
