Title:
CENTRIFUGE AND ROTOR USED IN SAME
Document Type and Number:
WIPO Patent Application WO/2022/070536
Kind Code:
A1
Abstract:
This invention reduces variation in amounts of cleaning liquid fed into a plurality of test tubes in a cleaning liquid introduction step for a centrifuge for cleaning blood cells or other living cells. A cleaning liquid distribution element (50) attached to an upper portion of a rotor body (31) comprises an upper distribution element (51) and lower distribution element (61) and is fed cleaning liquid from a cleaning liquid introduction opening (54) during the rotation of a rotor (30). The cleaning liquid enters into a recessed inside part of the lower distribution element (61). The cleaning liquid that has entered the inside part is moved radially outward by centrifugal force from the vicinity of the center of rotation so as to climb an inclined part (64). A plurality of cleaning liquid passages (67) are radially formed at a lower annular part at the distal end of the inclined part (64), and the cleaning liquid is discharged radially outward from discharge openings (67b) in the cleaning liquid passages (67). The formation of the inclined part (64) makes it possible to evenly distribute the cleaning liquid into test tubes (80).
