PROBLEM TO BE SOLVED: To provide an inexpensive centrifuge which can easily be manufactured in particular and whose pipeline is exposed to a relatively less mechanical load so that the number of its revolution can be enhanced. SOLUTION: The centrifuge which has a rotation frame 1 installed on a stand 2 that can be revolved and a separation unit 4 that can revolve around a central rotation axis A with twice the revolution of the rotation frame toward the same revolving direction, where the pipeline 6 that supplies or discharges a liquid is connected with the separation unit 4 and led to a static connection site 5 in a loop state around the separation unit. At least one guide element 7, 8 is provided to support the pipeline and has a support surface 10 for the pipeline. The support surface of the guide element is composed of a rotation plane curved line, while a radius R2 of each curvilinear circle contacting with the curved line at one point increases when a distance between a point of contact and the central rotation axis A is increased. An abrasion in this status is uniform over the whole surface of contact and the life span becomes longer accordingly. COPYRIGHT: (C)2003,JPO
