PROBLEM TO BE SOLVED: To miniaturize a desk-top centrifugal separation device and to reduce the cost by enabling to change the attitude of a sample tube from the vertical attitude at the time of stopping a spinner to the horizontal attitude during the centrifugal operation without using a mechanical supporting structure of a sample tube such as gyro supporting in a desk-top centrifugal separating device. SOLUTION: A downward corn type rotary disk 52 around the position of a spindle shaft 31 of a driving motor 30 is provided on a spinner 50 driven by the driving motor 30, plural fitting holes H2, H2... for fitting the sample tube are formed into long holes or elliptical long holes long in the radial direction of a direction, to which the centrifugal forced is worked, on the rotary disk 52. The sample tube is let fall and fitted into each fitting hole H2 to enable to swing the lower end part by the centrifugal force in a range of the length of the long fitting holes H2, H2.... |
