SELF-DRIVING CENTRIFUGE OF THROW AWAY TYPE

摘要

PROBLEM TO BE SOLVED: To provide a self-driving centrifuge (20) of a throw away type. SOLUTION: The self-driving centrifuge (20) of the throw away type has a preassembly (21) constituted by stacking cones on each other and has first and second rotor shell sections (22 and 23). The rotor shell sections (22 and 23) are constituted by injection molding of plastic materials and the shells are formed by joining engaging edges (26 and 27) to each other. A plastic hub (25) of an injection molding is assembled into the central opening existing in the lower half of the rotor shells and is extended upward to enter the hollow inside. A centering spool (24) is assembled to the central opening existing in the upper half of the rotor shells and is extended downward to enter the hollow inside.
