A laboratory centrifuge is a piece of equipment generally driven by an electric motor and some older ones usually spun with hand, that puts an object in a rotation around a fixed axis, applying a force perpendicular to the axis. It spun liquid samples at high speeds and thus creates a strong centripetal force causing the denser materials to travel toward the bottom of the centrifuge tube more rapidly than they would under the force of normal gravity. The present high cost of imported centrifuges necessitates the design and construction of an electrical centrifuge using local raw materials. The use of steel for the construction of the body, and aluminum for the centrifuge head, rotor and buckets, made the centrifuge cheaper and more adaptable to the local environment. The inner chamber which consists of four rotors could accommodate four test tubes at a centrifugation cycle. The average speed of a centrifuge is 100RPM (100 rotations per minutes) and the average time is five minutes while the maximum time is 10 minutes. The duration of successful centrifugation is 5 minutes. ...
