[0036] like Figure 1-Figure 8 As shown, the present embodiment provides an anti-skew test tube rack 100, which includes a rack body 1, an anti-skew component 2 and a card cover assembly 3. The rack body 1 is provided with a plurality of placement positions 11 for placing test tubes 200. The anti-skew component 2 is arranged one-to-one corresponding to the placement positions 11. The anti-skew component 2 includes a plurality of anti-skew blocks 21, and each anti-skew block 21 is arranged at a circumferential interval along the corresponding placement position 11. The anti-skew component 2 can support and limit the tube column 202 from the circumferential direction of the tube column 202 of the test tube 200 to prevent the tube column 202 from being skewed. The card cover assembly 3 can clamp the tube cover 201 of the test tube 200. The setting of the card cover assembly 3 can prevent the tube cover 201 from moving, making it easy to take liquids and pipette liquids; the setting of the anti-skew component 2 can play a role of circumferential support and limitation on the tube column 202, which can prevent the tube column 202 from tilting, making it easy to take liquids and pipette liquids, while also preventing the contents in the test tube 200 from spilling out, avoiding contamination of the anti-skew test tube rack 100, and avoiding wasting the contents.

[0037] Furthermore, each anti-skew block 21 is provided with a chamfer 22. Specifically, the chamfer 22 is provided on an end of each anti-skew block 21 away from the resting position 11. The provision of the chamfer 22 can prevent the end surface of the anti-skew block 21 away from the resting position 11 from scratching the tube column 202 of the test tube 200.

[0038] Furthermore, each anti-skew block 21 has a curvature so as to better fit with the tube column 202 of the test tube 200 and play a better supporting and limiting role.

[0039] Furthermore, a visual window 12 is provided on the rack body 1, through which the bottom of the tube column 202 can be seen, so as to check the pipetting situation and provide calibration for the pipetting. Specifically, the visual window 12 can be opened on the side of the rack body 1, and the visual window 12 can be a cavity.

[0040] In this embodiment, the size and number of the viewing windows 12 are not limited and can be set according to actual needs, as long as it is convenient to observe the remaining contents at the bottom of the column 202 to judge the pipetting situation.

[0041] It should be noted that a plurality of the shelves 11 are arranged in rows. Since the visual window 12 is provided on the side of the rack body 1, the test tubes 200 placed on the shelves 11 located on the outside can directly observe the bottom of the test tubes 200 through the visual window 12, and the test tubes 200 placed on the shelves 11 located on the inside may be blocked. In this embodiment, the visual window 12 is provided to set the moving path of the automated pipette tip, and it is not necessary to observe the bottom of the test tube 200 every time the pipetting is performed. Before the pipetting, it is necessary to perform a trial pipetting, observe the test tubes 200 row by row, and after the observation, remove the test tubes 200 in the row or column from the rack body 1, and then observe the next column or row. Therefore, there will be no situation where the test tubes 200 are blocked and cannot be observed. After observing multiple rows or columns of test tubes 200 before pipetting, the moving path of the automated pipette tip is determined, thereby obtaining the moving standard of the pipette tip. That is, after completing the trial pipetting, the pipette tip can pipette the test tube 200 within the moving path and ensure that the bottom of the test tube 200 is pipetted thoroughly before performing formal pipetting. After the formal pipetting, the pipetting situation at the bottom of the test tube 200 is no longer observed.

[0042] Furthermore, the anti-skew test tube rack 100 also includes a base 4, and the rack body 1 can be placed on the base 4. The base 4 can lift the test tube 200 located on the shelf position 11, so that the upper end of the tube column 202 of the test tube 200 is separated from the upper end surface of the shelf position 11, so as to facilitate the removal of the test tube 200 from the anti-skew test tube rack 100.

[0043] Furthermore, the bottom support 4 includes a ejector 42 , and a cavity 13 is opened on the rack body 1 . The cavity 13 is communicated with each of the placement positions 11 . The ejector 42 can extend into the cavity 13 and lift the test tube 200 .

[0044] Furthermore, the visual window 12 can be provided on the side of the rack body 1, and the visual window 12 is connected to the cavity 13. After the test tube 200 is placed on the shelf 11, the column 202 is partially located in the cavity 13, and the bottom of the column 202 can be seen through the visual window 12, thereby judging the pipetting situation.

[0045] Furthermore, the bottom bracket 4 also includes a base plate 41, and a ejector 42 is protruding from the base plate 41, and the rack body 1 can be placed on the base plate 41. When the test tube 200 is placed on the anti-skew test tube rack 100, the rack body 1 is not placed on the bottom bracket 4, and liquid transfer can be performed at this time; when the liquid transfer is completed and the test tube 200 needs to be removed from the anti-skew test tube rack 100, the anti-skew test tube rack 100 with the test tube 200 can be directly placed on the bottom bracket 4, and the test tube 200 can be lifted upward by the ejector 42, so that the upper end of the tube column 202 of the test tube 200 is separated from the upper end surface of the resting position 11, so as to facilitate the test tube 200 to be taken out of the anti-skew test tube rack 100.

[0046] Furthermore, the base 4 is made of plastic, and the frame body 1 is made of aluminum alloy.

[0047] Furthermore, the card cover assembly 3 includes a card block 31 , which is mounted on the frame body 1 . A card slot 32 is formed on the card block 31 , and the tube cover 201 can be carded in the card slot 32 .

[0048] Furthermore, the tube cover 201 includes a clamping portion 2011 , and the clamping portion 2011 can be clamped in the clamping slot 32 .

[0049] In this embodiment, there are multiple storage positions 11, which can be opened in rows and columns on the rack body 1. Each storage position 11 can hold a test tube 200. Each storage position 11 is provided with a clamping block 31 on two opposite sides, and the clamping portion 2011 is clamped between the two clamping grooves 32.

[0050] Furthermore, a receiving cavity 33 is provided on the card block 31, and the receiving cavity 33 is connected to the card slot 32. The tube cover 201 also includes an insertion portion 2012 that can be inserted into the tube column 202. The insertion portion 2012 and the card connection portion 2011 are integrally formed. The receiving cavity 33 can accommodate the insertion portion 2012 and the connecting portion 203 for connecting the tube cover 201 and the tube column 202.

[0051] Furthermore, the card cover assembly 3 also includes a card seat 34 , which is installed on the frame body 1 , and at least one card block 31 is provided on the card seat 34 .

[0052] In this embodiment, the anti-skew test tube rack 100 can be used to place test tubes 200 with a diameter of 8mm-11mm, the test tubes 200 are concentrically arranged with the shelf position 11, and the gap between the shelf position 11 and the test tubes 200 is 0.5mm-1.5mm. Of course, it is not limited to the above dimensions.

[0053] 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.
