The second clearance groove 500 is used by the user to pick up and put in the second connector 350 with their fingers or other tools. The third clearance groove 600 is used by the user to pick up and put in the needle 310 and the needle protective sleeve 320 with their fingers or other tools. The fourth clearance groove 700 is used by the user to pick up and put in the first part 331 of the tubing with their fingers or other tools. The fifth clearance groove 800 is used by the user to pick up and put in the second part 332 of the tubing with their fingers or other tools.

[0054] refer to Figure 3 The first connector receiving portion 220 is used to house a pipette connector, namely the first connector 340 (see reference). Figure 4 The pipette 300 includes an annular protrusion 321 at the tail of the needle 310. The width of the first connector receiving portion 220 along the second direction Y is greater than the first width w1 of the needle receiving portion 210 along the second direction Y and the second width w2 of the first tubing receiving portion 230 along the second direction Y. The first connector receiving portion 220 includes a first portion 221, a second portion 222 and a third portion 223. The second portion 222 is connected to the first clearance groove 400. The third length h3 of the first portion 221 along the first direction X is greater than the fourth length h4 of the third portion 223 along the first direction X.

[0055] Specifically, refer to Figure 4The first connector 340 includes a first connector first part 341, a first connector second part 342, and a first connector third part 343. The first part 221 is used to place the first connector first part 341 and the annular protrusion 321, and the third part 223 is used to place the first connector third part 343. Therefore, the third length h3 of the first part 221 along the first direction X must be greater than the fourth length h4 of the third part 223 along the first direction X. The first connector second part 342 is disposed in the intersection area of ​​the second part and the first clearance groove 400. Since the first clearance groove 400 extends along the second direction Y, the width of the first connector second part 342 along the second direction Y is not limited by the width of the first connector receiving part 220 along the second direction Y.

[0056] It should be noted that, given that the first connector 340 needs to be fitted onto the outer surface of the needle 310 and the first part of the tubing 331 along the axial direction, the length and width of the first connector 340 along the second direction Y must be greater than the width of the needle 310 and the first part of the tubing 331 along the second direction Y.

[0057] refer to Figure 4 The width of the first connector receiving portion 220 along the second direction Y is less than the width of the first connector 340 along the second direction Y. That is, the third width w3 of the first portion 221 along the second direction Y and the fourth width w4 of the third portion 223 along the second direction Y are respectively less than the width of the first connector 340 along the second direction Y. The width of the first connector receiving portion 220 along the second direction Y is less than the first diameter D1 of the annular protrusion 321. The first connector receiving portion 220 is used for interference fit with the first connector 340 and the annular protrusion 321.

[0058] Specifically, the first part 341 and the third part 343 of the first connector are respectively interference-fitted with the first part and the third part, thereby ensuring that the first connector 340 can be firmly fixed to the first connector receiving part 220.

[0059] For example, both the first portion 341 and the third portion 343 of the first connector are cylindrical structures. Therefore, the third width w3 of the first portion 221 along the second direction Y and the fourth width w4 of the third portion 223 along the second direction Y are smaller than the second diameter D2 of the first portion 341 and the third diameter D3 of the third portion 343, respectively, thereby achieving an interference fit. However, those skilled in the art will understand that in other embodiments, the first portion 341 and the third portion 343 of the first connector can be other shapes, such as cuboids, cubes, etc., as long as the maximum width of the first portion 341 and the third portion 343 along the second direction Y is greater than the width of the first portion along the second direction Y and the width of the third portion along the second direction Y, respectively. This application does not impose any limitations on this.

The second part 352 is located in the fifth part 242, which is the intersection area of ​​the fifth part 242 and the second clearance groove 500. Since the second clearance groove 500 extends along the second direction Y, the width of the second part 352 along the second direction Y is not limited by the width of the second connector receiving part 240 along the second direction Y.

[0062] refer to Figure 6 The width of the second connector receiving portion 240 along the second direction Y is less than the width of the second connector 350 along the second direction Y. That is, the sixth width w6 of the fourth portion 241 along the second direction Y and the seventh width w7 of the sixth portion 243 along the second direction Y are respectively less than the width of the second connector 350 along the second direction Y. The second connector receiving portion 240 is used for interference fit with the second connector 350.

[0063] Similarly, the first part 351 of the second connector 350 is interference-fitted with the fourth part 241, and the third part 353 of the second connector is interference-fitted with the sixth part 243, thereby ensuring that the second connector 350 can be more firmly fixed to the second connector receiving part 240.

[0064] For example, both the first portion 351 and the third portion 353 of the second connector are cylindrical structures. Therefore, the sixth width w6 of the fourth portion 241 along the second direction Y and the seventh width w7 of the sixth portion 243 along the second direction Y are smaller than the fourth diameter D4 of the first portion 351 and the fifth diameter D5 of the third portion 353, respectively, thereby achieving an interference fit. However, those skilled in the art will understand that in other embodiments, the first portion 351 and the third portion 353 of the second connector can be other shapes, such as cuboids, cubes, etc., as long as the maximum width of the first portion 351 and the third portion 353 along the second direction Y is greater than the width of the fourth portion 241 along the second direction Y and the seventh width w7 of the sixth portion 243 along the second direction Y, respectively. This application does not impose any limitations on this.

[0065] It should be noted that in this embodiment, the first connector 340 and the second connector 350 are the same shape and size. However, those skilled in the art will understand that in other embodiments, the first connector 340 and the second connector 350 may have different shapes and sizes, and this application does not impose any restrictions on this.

[0066] refer to Figure 7 The first depth d1 of the first connector receiving portion 220 is greater than the second depth d2 of the needle receiving portion 210 and the third depth d3 of the first tubing receiving portion 230, and the first portion 221, the second portion 222, and the third portion 223 have the same depth; the fourth depth d4 of the second connector receiving portion 240 is greater than the third depth d3 of the first tubing receiving portion 230 and the fifth depth d5 ​​of the second tubing receiving portion 250, and the fourth portion 241, the fifth portion 242, and the sixth portion 243 have the same depth.

In other words, the bottoms of the needle receiving portion 210, the first connector receiving portion 220, the first tubing receiving portion 230, the second connector receiving portion 240, and the second tubing receiving portion 250 are respectively arc-shaped.

[0069] However, those skilled in the art will understand that in other embodiments, the bottom of the needle receiving portion 210, the first connector receiving portion 220, the first tubing receiving portion 230, the second connector receiving portion 240, and the second tubing receiving portion 250 may be other shapes, such as squares, triangles, etc., and this application does not limit them in this regard.

[0070] refer to Figures 9 to 11 The side wall 900 of the pipette tray 100 is inclined inward along the third direction Z. Several protrusions 910 are provided on the side wall at intervals. The side wall 900 and the protrusions 910 form a pipette tray receiving cavity 920, which is used to place another pipette tray 100. The third direction Z is perpendicular to the first direction X and the second direction Y, respectively.

[0071] Specifically, the side wall 900 of the pipette tray 100 is inclined inward along the third direction Z, that is, the pipette tray 100 is arranged in a trapezoidal shape, and several spaced protrusions 910 are provided on the side wall 900, which can form a stable nested receiving cavity, realize the stacking and storage of multiple pipette trays 100, and ensure the stability during stacking, effectively reduce space occupation, and facilitate the transportation of a large number of pipette trays 100.
