Title:
ROTOR FOR CENTRIFUGE, AND CENTRIFUGE
Document Type and Number:
WIPO Patent Application WO/2021/100333
Kind Code:
A1
Abstract:
When this centrifuge is operated, local stress applied to a liquid-feeding groove formed in the upper surface of a rotor core is averaged to minimize deformation of the rotor core. A rotor core 40, which is mounted inside a rotor used for continuous centrifugation, has a columnar solid section 41, blades 58 expanding radially outward from the solid section 41, and a disc section 44 extending radially outward from the upper surface of the solid section 41, the upper surface of the rotor core 41 being provided with a liquid-feeding grove 52 that continues radially outward from the center vicinity to the outer side. A stress-mitigating groove 57 that extends radially outward is formed in the lower surface of the liquid-feeding grove 52. The stress-mitigating groove 57 is formed in a position overlapping the position of the liquid-feeding grove 52 when the disc section 44 is viewed along the axial direction.
