Electric laboratory centrifuge is a desktop centrifuge and widely applied in biological, chemical, pharmaceutical and other research and production departments of education, its maximum speed could reach 4000 rpm/min for the separation and identification and radioimmunoassay cells and large particles and so on. A centrifuge is a piece of equipment, generally driven by an electric motor , that puts an object in rotation around a fixed axis, applying a force perpendicular to the axis. A centrifuge is also used to separate the components of blood in blood banks. The centrifuge works using the sedimentation principle, where the centripetal acceleration causes denser substances to separate out along the radial direction (the bottom of the tube). By the same token lighter objects will tend to move to the to top.
