Embodiment Construction

[0029] figure 1 An exemplary centrifuge rotor 10 according to an embodiment of the invention is shown. The rotor 10 includes a rotor body 12 having an upper surface 14 and being symmetrical about an axis of rotation 16 of the rotor body 12 about which a sample (not shown) is centrifugally rotated. An elongated stiffener 18 surrounds a circumferentially extending sidewall 19 of the rotor body 12 ( image 3 ) substantially smooth outer surface 20 extending continuously. As used herein, the term "substantially smooth" to describe the outer surface 20 is intended to describe the surface 20 having no stepped configuration and substantially no corners or sharp edges. Accordingly, the terms defined above are not intended to define the surface roughness of surface 20 . Furthermore, the rotor body 20 may be shaped such that the substantially smooth outer surface 20 requires no additional machining or finishing prior to the application of the reinforcement 18 .

Abstract

A fixed angle centrifuge rotor is provided. The rotor includes a rotor body having a circumferential sidewall and a plurality of tubular cavities. Each of the cavities has an open end and a closed end and is configured to receive a sample container therein. A pressure plate is operatively coupled to the plurality of tubular cavities so that the pressure plate, in combination with the plurality of tubular cavities, defines an enclosed hollow chamber between each adjacent pair of the plurality of tubular cavities. Each of the plurality of tubular cavities has a sidewall facing an interior of the rotor body and a bottom wall at the closed end.

Description

[0001] cross reference [0002] This application claims priority on the filing date of US Patent Application Serial No. 12 / 616,276, filed November 11, 2009, the entire contents of which are expressly incorporated herein by reference in their entirety. technical field [0003] The present invention relates generally to centrifuge rotors, and more particularly to fixed angle rotors for centrifuges. Background technique [0004] Centrifuge rotors are commonly used in laboratory centrifuges to hold samples during centrifugation. Although centrifuge rotors can vary significantly in construction and size, a common rotor construction is a fixed-angle rotor with a solid rotor body within which are distributed radially and symmetrically about the axis of rotation a plurality of unit bore cavities . Samples are placed in cavities such that multiple samples can be subjected to centrifugation. [0005] Conventional fixed angle centrifuge rotors can be made of metal or various other m...
