Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-2, a magnetic annular centrifuge tube rack comprises an upper rack body 1, a lower rack body 2, a placing disc 3, an annular magnetic ring 4 and a disc-shaped magnetic ring 5.

The lower support body 2 is in the shape of a circular groove with an open upper end, and the upper support body 1 is in the shape of a circular groove with an open lower end. Go up support body 1 with lower support body 2 is mutually supported, 1 lower extreme of going up support body is equipped with

spacing boss

101, 2 upper ends of lower support body be equipped with the corresponding spacing groove of spacing boss 101. The annular magnetic ring 4 is embedded in the upper frame body 1, the disc-shaped magnetic ring 5 is embedded in the lower frame body 2, the annular magnetic ring 4 and the disc-shaped magnetic ring 5 are both axially magnetized magnets, and the annular magnetic ring 4 and the disc-shaped magnetic ring 5 are mutually attracted. When the upper frame body 1 is placed on the lower frame body 2, the limiting boss 101 on the upper frame body 1 corresponds to the limiting groove on the lower frame body 2, and the upper frame body 1 and the lower frame body 2 are relatively fixed through mutual attraction of the annular magnetic ring 4 and the disc-shaped magnetic ring 5.

A plurality of centrifugal tube placing holes 102 are formed in the upper frame body 1 along the circumferential direction. When the centrifuge tube 6 is placed on the magnetic annular centrifuge tube rack, the bottom of the centrifuge tube 6 is supported on the bottom surface inside the lower rack body 2, the tube wall in the middle of the centrifuge tube 6 is tightly attached to the inner annular surface of the annular magnetic ring 4, and the tube wall at the lower part of the centrifuge tube 6 is tightly attached to the inner annular surface of the disc-shaped magnetic ring 5.
