Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

As shown in fig. 1 and 2, an anti-overflow centrifuge tube comprises a tube body 1, a fixing seat 2 and a supporting seat 10, wherein the top of the tube body 1 is provided with a corresponding top cover 3 through the fixing seat 2, the bottom of the top cover 3 is provided with a positioning rod 4, the periphery of the positioning rod 4 is sleeved with a positioning block 5, and the periphery of the positioning rod 4 is sleeved with a spring 6 at the bottom of the positioning block 5.

The bottom of the tube body 1 is sleeved with a supporting seat 10, a limiting ring 11 is arranged at the top of the supporting seat 10, and an amplifying lens 12 is arranged between the supporting seat 10 and the limiting ring 11.

In this embodiment, as shown in fig. 1, through the supporting seat 10 and the magnifying lens 12, the centrifuge tube can be supported in an auxiliary manner, and meanwhile, an operator can observe the bottom of the centrifuge tube conveniently.

The fixing seat 2 is internally provided with an opening 9, two sides of the top of the fixing seat 2 are provided with limiting grooves 7 corresponding to the positioning rods 4, and two sides of the fixing seat 2 are provided with inserted bars 8 corresponding to the positioning blocks 5 through reserved holes.

In this embodiment, as shown in fig. 4, the positioning rod 4 and the positioning block 5 are conveniently subjected to the limiting and fixing treatment through the limiting groove 7 and the inserting rod 8.
