Abstract
A rotor body () for a laboratory centrifuge includes a rotor hub () which is inserted in a central opening and on the outside of which, at least one helically curve continuous groove () runs so as to form a transport facility for cooling air. The cooling air is effective in the direction of the axis () of the rotor hub () between the upper side () and the underside () of the rotor (). In this manner, a cooling airstream which runs axially through the rotor () and undergoes direct thermal exchange with the rotor () and the mixtures to be treated in the laboratory centrifuge can be realized. No additional installation volume is required for this measure and equalization of the temperature of the rotor and the housing accommodating the rotor can be achieved.
