How a Centrifuge Works - Drucker Diagnostics

Filtering does not work to centrifuge blood samples because the blood components are too small. In either method, the particles are suspended in liquid and separated in the centrifuge machine. The separation happens due to centrifugal force, which pushes objects outward – toward the tip of the tube, in the case of blood tubes – as they are
