摘要： A rotor includes a plurality of holding cavities for holding specimen containers, respectively. A transverse cross sectional shape of the holding cavity is a substantially triangular shape having one vertex on an inner circumference side of the rotor. Two vertices of the substantially triangular shape are arranged on an outer circumference side of the rotor so as to have equidistance from a rotary shaft of the rotor. Spacing between sides of the substantially triangular shape in a circumferential direction of the rotor gradually increase over 60% or more a radial length of the holding cavity from an innermost circumferential position to the outer circumference side of the rotor when viewed in its transverse plane.

摘要： A centrifugal separator includes: a sample line; and a rotating apparatus portion including a rotor that has a rotor chamber. The centrifugal separator centrifugally separates a sample by supplying the sample from the sample line into the rotor and driving to rotate the rotor in the rotor chamber and discharges the centrifugally separated sample from the rotor via the sample line. The centrifugal separator includes: a sterilizing apparatus for sterilizing at least a portion with which the sample is brought into contact by making a sterilizing fluid flow through the sample line.

摘要： A desk-top centrifuge is provided which includes a switching element disposed between a dc power supply and a motor and a controlling circuit. The controlling circuit receives a voltage of power regenerated by the motor to provide a pulse width-controlled on-off signal to the drive switching element to control speed of the motor. The controlling circuit increases an on-duration in which the on-off signal is at an on-level at a given rate to turns the motor slowly. The centrifuge has a safety guard system made up of a door switch and a door lock switch which are installed in series between the dc power supply and the motor and work to establish electric communication between the dc power supply and the motor when the door is closed and locked.
