Abstract:
1. A centrifugal separator comprising: a plurality of specimen containers; a rotor having a plurality of holding cavities for holding each of the plurality of specimen containers, respectively; a drive unit that rotates the rotor; and a rotor chamber that accommodates the rotor; wherein a transverse cross sectional shape of each of the plurality of holding cavities is a substantially triangular shape having one vertex on an inner circumference side of the rotor, wherein 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, and wherein a spacing between sides of the substantially triangular shape in a circumferential direction of the rotor gradually increases 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, wherein a transverse cross sectional shape of each of the specimen containers is a substantially equilateral triangle, and each of the plurality of specimen containers are configured to be inserted into each of the plurality of holding cavities which are arranged at a plurality of positions in a circumferential direction, and wherein a diameter of the rotor is between 350 mm and 450 mm, a height of the rotor body is between 200 mm and 250 mm, and a specimen capacity of each of the plurality of specimen containers is greater than 1200 ml.
