Abstract
A centrifuge arrangement comprises a rotor mounted for rotation about an axis and a relatively thin-walled, onepiece, conically-shaped container having a circumferential wall and an upper and a lower portion integrally connected with the circumferential wall. The lower portion is adhesively secured to a rotor with a hardenable substance which cures over a period of time, thus permitting adjustment of the connection between the container and the rotor so that they rotate without causing undesirable vibrations. A rolling method of making the conically-shaped container is also disclosed.
