[0035] like Figure 1-Figure 6 As shown, the present embodiment provides a test tube rack 100, which includes a rack body 1, a visual window 2 and a positioning assembly 3. A plurality of shelf positions 11 are provided on the rack body 1, each shelf position 11 includes a plurality of test tube holes 111, and the number of test tube holes 111 included in each shelf position 11 is equal to the number of test tubes included in the row of test tubes 200, so as to adapt to the row of test tubes 200. The visual window 2 can show the bottom of the row of test tubes 200, and the positioning assembly 3 is arranged on the side of the shelf position 11 facing the bottom of the row of test tubes 200. The positioning assembly 3 can support and position each tube column of the row of test tubes 200 from the circumferential direction of the tube column of each test tube in the row of test tubes 200. The circumferential support positioning of the positioning component 3 enables the row of test tubes 200 to be placed in place on the shelf 11, so that the bottom surfaces of each test tube in the row of test tubes 200 are on the same horizontal plane, which makes it convenient for the pipetting head to move the same displacement in the height direction to achieve pipetting of the row of test tubes 200, and the pipetting situation can be checked through the visual window 2, thereby reducing the error of pipetting and ensuring the accuracy of the test results.

[0036] It should be noted that the row of test tubes 200 includes a plurality of test tubes arranged in sequence and integrated with each other, each test tube includes a tube column and a tube head, the tube heads of the plurality of test tubes are interconnected and formed as one body, and each tube column is placed corresponding to a test tube hole.

[0037] Of course, the test tube rack 100 provided in this embodiment is not limited to accommodating a row of test tubes 200, and can also accommodate a single test tube, which is not limited to this.

[0038] like Figure 1 As shown, the rack body 1 is also provided with an anti-slip strip 12. The provision of the anti-slip strip 12 can play an anti-slip role, making it easy to automatically grab the test tube rack 100.

[0039] like Figure 2 and Figure 3 As shown, the positioning assembly 3 includes a positioning block, which is arranged on the side of the placement position 11 facing the bottom of the tube of the row of test tubes 200, and a plurality of positioning blocks are arranged at intervals on the circumference of each test tube hole 111 to support and position the tube column of the row of test tubes 200.

[0040] Furthermore, the positioning block includes a first positioning block 31 and a second positioning block 32. The first positioning block 31 is arranged between two adjacent test tube holes 111, and at most one second positioning block 32 is arranged on the circumference of each test tube hole 111. In other words, the first positioning block 31 is shared between two adjacent test tube holes 111, and the second positioning block 32 is used alone for a circle of test tube holes 111 closest to the outer contour of the rack body 1. Such a setting can save the number of positioning blocks, and make reasonable use of the space of the test tube rack 100, thereby improving space utilization.

[0041] Specifically, in this embodiment, four positioning blocks are arranged on the circumference of each test tube hole 111 to support and position the tube column of the test tubes 200 in a row. The four positioning blocks may be four first positioning blocks 31, three first positioning blocks 31 and one second positioning block 32, or two first positioning blocks 31 and two second positioning blocks 32. Of course, the number of positioning blocks arranged on the circumference of each test tube hole 111 may also be other numbers, which is not limited thereto.

[0042] It should be noted that the first positioning block 31 is not only shared by two adjacent test tube holes 111 in each storage position 11 , but may also be shared by two adjacent test tube holes 111 in different storage positions 11 , and this is not limited.

[0043] In this embodiment, the test tube holes 111 can be arranged in rows, and the number of test tube holes 111 in each row or column can be an integer multiple of the number of test tubes included in the row of test tubes 200. The specific distribution position of the placement position 11 is not limited as long as it is convenient for placing the row of test tubes 200.

[0044] In other embodiments, positioning blocks on the circumference of each test tube hole 111 may also be provided separately.

[0045] Furthermore, two opposite cambered surfaces are arranged on the first positioning block 31 to match the cylindrical surfaces of two adjacent tube columns. Such arrangement facilitates two adjacent test tube holes 111 to share the same first positioning block 31 .

[0046] Correspondingly, a curved surface can be directly provided on the second positioning block 32 to provide good support and positioning for the pipe column.

[0047] Furthermore, chamfers are provided on the curved surfaces of the first positioning block 31 and the second positioning block 32 to prevent the pipe column from being scratched and to protect the pipe column to a certain extent.

[0048] like Figure 1 , Figure 4-Figure 6As shown, the test tube rack 100 further includes a flange 4, which is protruding from the rack body 1. When multiple test tube racks 100 are stacked, the flange 4 can cover the rack body 1 of another adjacent test tube rack 100 to prevent the stacked test tube racks 100 from tipping over.

[0049] Furthermore, the flange 4 and the rack body 1 form a boss 6 . When a plurality of test tube racks 100 are stacked, the boss 6 can abut against the rack body 1 of another adjacent test tube rack 100 .

[0050] Furthermore, the test tube rack 100 further includes a support platform 5 , which is connected to the boss 6 . When a plurality of test tube racks 100 are stacked, the support platform 5 can support the rack body 1 of another adjacent test tube rack 100 .

[0051] Specifically, the size of the support platform 5 is larger than that of the boss 6. When multiple test tube racks 100 are stacked, and one of the rack bodies 1 is misaligned on the boss 6 of the adjacent test tube rack 100, the support platform 5 can prevent the test tube rack 100 from tilting, making it easier to stack.

[0052] Furthermore, a first cavity 13 is formed on the frame body 1 , and a second cavity 41 is formed on the flange 4 . The first cavity 13 and the second cavity 41 are communicated with each other, and the boss 6 and the support platform 5 are both disposed in the first cavity 13 and the second cavity 41 .

[0053] Furthermore, the flange 4 and the rack body 1 are provided with a plurality of viewing windows 2 at intervals along their outer contours, so as to facilitate observation of the bottoms of the row of test tubes 200 from multiple directions, so as to understand the pipetting conditions of the pipetting head. Specifically, the viewing windows 2 can be provided on the sides of the flange 4 and the rack body 1.

[0054] Specifically, each viewing window 2 is connected to the first chamber 13 and the second chamber 41 so as to observe the pipetting conditions at the bottom of the row of test tubes 200 .

[0055] It should be noted that the test tube holes 111 can be arranged in rows. Since the visual window 2 is provided on the side of the rack body 1 and the flange 4, the row of test tubes 200 placed on the outer shelf position 11 can directly observe the bottom of the row of test tubes 200 through the visual window 2, and the row of test tubes 200 placed on the inner shelf position 11 may be blocked, making it inconvenient to observe. In this embodiment, the setting of the visual window 2 is to facilitate the setting of the moving path of the automated pipetting head, and it is not necessary to observe the bottom of the row of test tubes 200 every time the pipetting is performed. Before the pipetting, it is necessary to perform a trial pipetting, observe the row of test tubes 200 row by row or column by column, remove the row of test tubes 200 from the rack body 1 after observation, and then observe the next column or row, so there will be no situation where the row of test tubes 200 is blocked and cannot be observed. Before pipetting, multiple rows or columns of test tubes 200 are observed to determine the moving path of the automated pipette tip, thereby obtaining the moving standard of the pipette tip. That is, after completing the trial pipetting, the pipette tip can pipette the test tubes 200 in a row within the moving path, and ensure that the bottom of the test tubes 200 is pipetted thoroughly before performing formal pipetting. After the formal pipetting, the pipetting situation at the bottom of the test tubes 200 is no longer observed.

[0056] Although the utility model has been described in detail above by means of general description, specific implementation methods and tests, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
