A flying leads assembly includes a flying lead having an inner layer which forms a liquid passage and an outer layer which acts as a sacrificial layer in use, thereby allowing integrity of the passage to be maintained for a long period of time. A further layer is provided intermediate the inner and outer layers which can be used to provide support to the assembly. The flying lead assembly, or a number of assemblies, are then located in a guide with lubricant material.

A centrifuge apparatus includes a plurality of modules, each including a rotatable body, housing and flying leads, assembly. The modules can be selectively interconnected to allow adaptation of the processing capacity of the apparatus to process a liquid to remove components therefrom and/or to process a number of different liquids and allow the separation of one or more types of components therefrom simultaneously.

Provided is a centrifuge. In a centrifuge having a rotor with a rotor body that holds a sample and that is rapidly rotated, an inclined surface that extends upward as it extends radially outward is formed on an upper-side outer peripheral portion of the rotor, in a region that is at a radially outward side and at an upper side of the outer edge of an opening. The inclined surface is a continuous ring-like inclined surface that has the same cross-sectional shape in the circumferential direction and is formed into a straight-line shape or a curved-line shape in cross-section along a rotation central axis. Although winds occur during high-speed rotation of the rotor, the winds are rectified by the inclined surface, and a component force for pressing the rotor body in a downward direction acts thereon.

Accurate measurement of acceleration caused by imbalance in the balance of a rotor is realized even in high-speed rotation with an acceleration sensor which has a processing speed required in low-speed rotation and a control unit. A centrifuge according to the present invention includes a rotor, a drive source for rotating the rotor, a rotating shaft for coupling the rotor and the drive source, an acceleration sensor, and a control unit. The acceleration sensor outputs values indicating acceleration in two different directions which are perpendicular to an axial direction of the rotating shaft. The control unit obtains an acceleration corresponding value, which is a value corresponding to acceleration in a direction perpendicular to the axial direction of the rotating shaft, based on values indicating acceleration in the two different directions and stops rotation of the rotor in a case where the acceleration corresponding value satisfies a determination criteria.
