[0025] In order to make the purpose, technical solution and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] See Figures 1 - 6 , the purpose of the present utility model is to provide a Pasteur pipette rack, which includes a base 1 and a box body 2 installed on the base 1. The base 1 is a triangular prism structure, and one of the sides of the triangular prism can be placed downward on the tabletop, and the box body 2 is fixedly connected to another side of the triangular prism, forming an obliquely placed box body 2.

[0027] The box body 2 includes a pipette placement rack 3 fixedly connected to the base 1 and a hinged top cover 4 hingedly connected to the top of the pipette placement rack 3. A number of first pipette platforms 31 and a number of first pipette clips 32 are fixedly connected to the pipette placement rack 3. The first pipette clips 32 are arranged above the first pipette platforms 31. The first pipette platforms 31 are provided with recesses, and the first pipette clips 32 are provided with "U" - shaped grooves.

[0028] The Pasteur pipettes used in medical experiments usually have a relatively long pipette part and a thicker rubber part at the top of the pipette part. After the Pasteur pipette sucks the reagent liquid or the prepared cell liquid, it usually needs to be placed on a rack. When using this Pasteur pipette placement rack, the Pasteur pipette with the sucked liquid can be inverted on the first pipette placement table 31, and the top of the rubber part is placed on the concave part on the first pipette placement table 31 at this time. The concave part on the first pipette placement table 31 plays a supporting role, and the pipette part of the Pasteur pipette is placed on the "U"-shaped groove on the first pipette clip 32. Since the whole box body 2 is obliquely arranged, the Pasteur pipettes are also obliquely placed after being placed and will not fall over. The staff can easily place multiple Pasteur pipettes with sucked liquid.

[0029] Preferably, a storage cavity 11 with both ends penetrating is provided inside the base 1, and cavity covers 12 are installed at the openings at both ends of the storage cavity 11. The cavity covers 12 are detachably installed at the openings at both ends of the storage cavity 11. The staff can place tools inside the storage cavity 11, such as wiping tools or extra unused Pasteur pipettes. It can better complete the classified placement of experimental supplies and is convenient for storage.

[0030] Preferably, the hinged top cover 4 is hingedly connected to the top of the pipette rack 3 through a hinge point 40. The hinged top cover 4 can be closed on the pipette rack 3. When the device is not in use, the hinged top cover 4 can play a role in blocking dust for the Pasteur pipettes.

[0031] Preferably, a plurality of second pipette placement tables 41 and a plurality of second pipette clips 42 are fixedly connected to the hinged top cover 4. Specifically, when the hinged top cover 4 is closed on the pipette rack 3, the second pipette placement tables 41 and the second pipette clips 42 can be alternately arranged with the first pipette placement table 31 and the first pipette clip 32 respectively to prevent the internal structures from interfering with each other when the device is closed.

[0032] Preferably, a fixed card 121 is fixedly connected to the cavity cover 12, and a card slot 13 matching the fixed card 121 is provided on the inner side surface of the storage cavity 11. When the cavity cover 12 is closed on both ends of the base 1, the fixed card 121 can be clamped inside the card slot 13 to achieve a more reliable connection between the two.

[0033] Preferably, an "L"-shaped dust-proof cover 5 is fixedly connected to the top of the pipette rack 3. When the hinged top cover 4 is closed on the pipette rack 3, the pipette rack 3, the hinged top cover 4 and the dust-proof cover 5 can jointly form a closed space to achieve a better dust-proof effect.

[0034] Preferably, when the hinged top cover 4 is closed on the catheter placing rack 3, the first catheter placing platform 31 on the catheter placing rack 3 and the second catheter placing platform 41 on the hinged top cover 4 are staggered, and the first catheter placing platform 31 is arranged at the top of the second catheter placing platform 41. When a Pasteur pipette is placed on the first catheter placing platform 31, and then the hinged top cover 4 is closed at this time, the second catheter placing platform 41 will not interfere with the Pasteur pipette. At the same time, at this time, the first catheter clamp 32 is located at the top of the second catheter clamp 42, and the "U"-shaped groove on the second catheter clamp 42 can also ensure that the second catheter clamp 42 does not interfere with the Pasteur pipette. Thus, it can be realized that the device can be closed when the Pasteur pipette is stored inside the device, which is convenient for storing the Pasteur pipette.

[0035] Certainly, the present utility model can also have many other embodiments. Without departing from the spirit and essence of the present utility model, those skilled in the art can make various corresponding changes and deformations according to the present utility model. However, these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present utility model.
