[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0030] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0031] This utility model embodiment provides a rotary pipette holder, such as Figures 1-7 As shown, the rotary pipette holder includes:

[0032] The protective cover 100 includes an outer cover 110 and an upper end plate 150 disposed at one end of the outer cover 110. The side wall of the outer cover 110 is provided with an open window 120 for picking up and putting in a pipette.

[0033] The base 200 includes a support 210, a column 220 with the support 210 at its center, and a number of partition plates 230 arranged in a ring around the column 220. The partition plates 230 divide the outer side of the column 220 into several storage areas. A sealing plate 240 is also provided between the partition plates 230, and the sealing plate 240 is connected to the end of the partition plate 230 away from the support 210.

[0034] The storage area is formed by a partition plate 230, a sealing plate 240, a support base 210 and a column 220 to create a semi-enclosed structure, and the pipette is placed inside the storage area. The semi-enclosed structure facilitates the formation of an independent storage space, reduces the influence of the external environment on the pipette, and allows the pipette to be stored in a relatively independent space.

[0035] The storage area is also provided with an upper hanging rod 251 and a lower hanging rod 252 for supporting the pipette. Both the upper hanging rod 251 and the lower hanging rod 252 are arc-shaped structures. The two ends of the upper hanging rod 251 and the lower hanging rod 252 are connected to the partition plate 230. The top handle of the pipette is hung on the upper hanging rod 251, and the bottom of the pipette rests on the lower hanging rod 252. The diameter of the upper hanging rod 251 is smaller than that of the lower hanging rod 252, and the pipette can be tilted and leaned against the upper hanging rod 251 and the lower hanging rod 252.

[0036] The outer cover 110 is made of a transparent material, allowing direct observation of the interior of the protective cover 100 when selecting it.

[0037] The protective cover 100 is nested outside the base 200. The upper end plate 150 is provided with a second bearing ring at its center. The upper end plate 150 is rotatably connected to the column 220 through the second bearing ring. The outer edge of the support base 210 is provided with a first bearing ring 270. The outer cover 110 is connected to the outer wall of the first bearing ring 270. The end of the outer cover 110 away from the upper end plate 150 is rotatably connected to the support base 210 through the first bearing ring 270. The base 200 does not participate in the rotation. The pipette will be placed statically in the storage area on the base 200. Therefore, during the selection process, the protective cover 100 can be rotated and the open window 120 on the protective cover 100 can be aligned with the corresponding storage area. The pipette will not participate in the rotation during the selection process, reducing interference during the selection process.

[0038] It should be noted that at least one set of storage areas is not used for pipette storage. The storage area not used for pipette storage is mainly used as the dwell area of ​​the open window 120. When storing pipettes, this set of storage areas is in a long-term open state. When other pipettes need to be selected, rotate to the corresponding storage area, and after the selection or storage is completed, rotate back to this set of storage areas. The purpose of this is to keep the length of the storage area responsible for storing pipettes in an independent environment.

[0039] The protective cover 100 and the base 200 cooperate to form a storage environment relatively independent of the laboratory environment, reducing the interference of the external environment on the pipettes in the storage state. Several sets of storage areas are constructed inside the protective cover 100 to independently divide and store the pipettes. The partition plate 230 keeps different pipettes separate from each other and prevents them from sliding due to external interference, further reducing the influence between pipettes. At the same time, different pipettes can be stored in an independent storage environment, which is convenient for distinguishing and selecting. The storage area has a fan-shaped structure, and the size of the open window 120 needs to be adapted to the size of the outer edge of the storage area. The pipettes enter and exit the storage area through the open window 120.

[0040] In a preferred embodiment of this invention, the outer cover 110 is further provided with an upper sealing ring 130, which abuts against the end face of the sealing plate 240 away from the support base 210. The outer cover 110 is provided with a connection port at the end away from the upper end plate 150. The connection port is located on the inner edge of the outer cover 110 and adopts a cylindrical countersunk hole structure. The inner edge of the connection port is connected to the outer wall of the first bearing ring 270. The end face of the connection port is provided with a lower sealing ring 140, which abuts against the end face of the first bearing ring 270 away from the support base 210.

[0041] In this embodiment, the function of the upper sealing ring 130 and the lower sealing ring 140 is to help achieve gap sealing and reduce the entry of external environmental substances.

[0042] As a preferred embodiment of this example, the top surface of the support base 210 is also provided with an ultraviolet lamp 280; when the pipette is stored in the storage area, the ultraviolet light emitted by the ultraviolet lamp 280 can sterilize the storage area and reduce the contamination of the storage area by bacteria and other microorganisms in the space.

[0043] In this embodiment, the ultraviolet lamp 280 uses ultraviolet lamp beads. Those skilled in the art can also set an annular groove on the top surface of the support base 210 and arrange the annular ultraviolet lamp in the groove to facilitate equipment maintenance and improve the sterilization effect. The ultraviolet lamp structure can also adopt a timer switch, which will automatically turn off after the operator leaves at a set time.

[0044] The support base 210 is equipped with a counterweight ring 260 to improve the stability of the equipment. The function of the counterweight ring 260 is to increase the overall stability of the base platform 200 and prevent the base platform 200 from shaking due to rotation.

[0045] It should be noted that, for the sake of simplicity, the foregoing embodiments are all described as a series of actions. However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to the present invention.
