By setting the liquid recovery mechanism, it is convenient to recover samples. It meets the need for convenient and reliable pipetting in biomedical experiments.
[0048] As Figures 1 to 6 shown in the figure, further, the test tube breaking mechanism 3 includes: a breaking thimble 31 and a test tube limiting wall 32. The top of the test tube limiting wall 32 is open, one side of the test tube limiting wall 32 is communicated with one end of the groove body 1, and the breaking thimble 31 is installed in the test tube limiting wall 32.
[0049] The beneficial effects of adopting the above further technical solution are as follows: the breaking thimble is used for positioning and breaking the bottom of the test tube for easily releasing liquid. The test tube limiting wall can prevent the released liquid from splashing and polluting the surrounding reagents or environment while limiting the test tube for easily releasing liquid.
[0050] Among them, the test tube limiting wall 32 can be square, circular, triangular, rhombic, oval or rectangular.
[0051] As Figures 1 to 6 shown in the figure, further, the breaking thimble 31 is a cross-shaped breaking thimble, and the breaking thimble 31 is located in the middle of the test tube limiting wall 32.
[0052] The beneficial effects of adopting the above further technical solution are as follows: the breaking thimble is used for positioning and breaking the bottom of the test tube for easily releasing liquid. The breaking thimble is located in the middle of the test tube limiting wall, which is convenient for positioning the test tube for easily releasing liquid with the breaking thimble and facilitating breaking the wall of the test tube for easily releasing liquid through the breaking thimble.
[0053] As Figures 1 to 6 shown in the figure, further, one side of the test tube limiting wall 32 is provided with a side opening 33, the side opening 33 is adapted to the groove body 1, and the side opening 33 of the test tube limiting wall 32 is communicated with one end of the groove body 1.

The test tube limiting wall can limit the test tube that can easily release liquid and prevent the splashing of the released liquid from polluting the surrounding reagents or the environment.
[0062] The bottom of the sample addition tank is asymmetrically conical, which is more in line with the inclination angle of the pipette during the sample addition operation.
