Description

Technical Field

[0001] This utility model belongs to the field of laboratory equipment technology and relates to a pipette rack. Background Technology

[0002] In modern biochemistry, medical testing, and various laboratory research, pipettes serve as fundamental and crucial experimental instruments for the precise transfer of liquid samples or reagents. With the continuous advancement of scientific research and technology, higher demands are placed on the operational precision and efficiency of pipettes. However, despite the relatively mature design of pipettes themselves, numerous challenges remain regarding their laboratory storage and management.

[0003] Traditionally, pipettes are stored in a simple and straightforward manner, often using simple support structures for easy access and placement. The main function of these supports is to provide a stable foundation, ensuring the pipettes stand upright without tipping over, and allowing researchers to quickly select the required pipette size. These support designs typically prioritize compatibility with multiple pipette sizes to accommodate the precise transfer of different liquid volumes, while also ensuring the materials are chemically resistant and the structure is stable to withstand the corrosive effects of common laboratory chemicals and guarantee long-term reliability.

[0004] However, most existing pipette holders use an open storage method, meaning the pipettes are exposed to air. While this method facilitates access, it also introduces significant problems—a markedly increased risk of cross-contamination. Especially when frequent sample changes are needed or sensitive samples are being processed, a complex cleaning procedure must be performed before and after each use to avoid any potential contamination. This process prolongs experimental preparation time and reduces overall work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a pipette holder that can seal and retain pipettes, reduce the number of times pipettes need to be cleaned, thereby shortening preparation time and improving overall work efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides a pipette holder, including a cover with openings at both the front and lower ends. A placement frame that can be pulled out from the front is provided inside the cover. A front cover that can cover the opening at the front of the cover is provided on the front side of the placement frame. An ultraviolet disinfection lamp is provided at the top of the cover. The placement frame is divided into a placement cavity with an upper opening and a water collection cavity at the lower end by a mesh drainage plate. Multiple horizontal partitions are arranged from bottom to top in the placement cavity. Each horizontal partition includes two opposing limiting partitions and a flexible interlayer between the two partitions. Each limiting partition has multiple circumferentially distributed and corresponding limiting holes. Each flexible interlayer has multiple elastic stabilizing holes that correspond one-to-one with the limiting holes. The inner wall of each elastic stabilizing hole protrudes inward to form a hole structure that is larger on the outside and smaller on the inside. The water collection cavity has an opening at the front and a water collection trough that can be pulled out from the front of the water collection cavity.

[0007] By adopting the above technical solution, when a pipette needs to be inserted, the placement frame is pulled out, and the pipette is passed from top to bottom through the limiting holes and elastic stabilizing holes of the two horizontal partitions. The inner wall of the elastic stabilizing hole is squeezed outward to allow the pipette to pass through. By clamping the inner wall of the pipette, the pipette is prevented from shaking when the placement frame is moved. Then, the placement frame is put back into the enclosure, and the ultraviolet disinfection lamp is controlled to perform timed ultraviolet disinfection. The water in the pipette drips into the water collection tank after passing through the mesh drain plate and is stored. The water collection tank is periodically removed and emptied.

[0008] The present invention is further provided that the lower end of the placement frame is equipped with multiple pulleys.

[0009] The present invention is further configured such that a Hall effect sensor switch for controlling the ultraviolet disinfection lamp is provided at the top of the cover body, and a magnet block cooperating with the Hall effect sensor switch is provided at the upper part of the rear side of the front cover body.

[0010] The present invention is further configured such that the flexible interlayer is made of elastic sponge material.

[0011] The present invention is further provided that a first handle is provided on the front side of the front cover.

[0012] The present invention is further provided with a second handle on the front side of the water collection and pumping trough.

[0013] The present invention is further configured such that both the cover and the front cover are made of opaque material.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Firstly, after placing the pipette into the placement frame, the placement frame is placed into the cover for sealed storage to prevent dust from entering. At the same time, it is also disinfected with ultraviolet light at regular intervals to effectively prevent microorganisms from growing on the inner wall of the pipette. Each time it is taken out for use, it does not need to be cleaned again. It only needs to be cleaned after use, which shortens the preparation time and improves the overall work efficiency.

[0016] Secondly, after placing the pipette into the placement frame, use the elastic stabilizing holes of the flexible interlayer to clamp the outer wall of the pipette, making it less prone to shaking and preventing damage caused by the pipette shaking when the placement frame is moved.

[0022] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the pipette holder proposed in this utility model. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0023] Example, refer to Figure 1-4A pipette holder includes a cover 1 with openings at the front and bottom. Inside the cover 1 is a pull-out placement frame 2, lower than the height of the cover 1. Four casters 3 are installed at the bottom of the placement frame 2 for easy removal. A front cover 4 covers the opening at the front of the placement frame 2. A vertically oriented first handle 5 is located on the front of the front cover 4. Both the cover 1 and the front cover 4 are made of opaque material. Two ultraviolet (UV) sterilization lamps 6 are installed at the top inside the cover 1. A Hall effect sensor switch 7 is positioned forward at the top inside the cover 1. A magnet 8, cooperating with the Hall effect sensor switch 7, is located on the upper rear side of the front cover 4. When the magnet 8 approaches the Hall effect sensor switch 7, it controls the UV sterilization lamps 6 to perform UV sterilization for 10-15 minutes. Removing the placement frame 2 and moving the magnet 8 away from the Hall effect sensor switch 7 turns off the UV sterilization lamps 6. The connection and power supply of circuit components can be done using conventional methods, so they will not be described in detail.

[0024] The placement frame 2 is divided into a placement cavity 10 with an upper opening and a water collection cavity 11 with a mesh drainage plate 9. The placement cavity 10 has two horizontal partitions arranged from bottom to top. Each horizontal partition includes two opposing limiting partitions 12 and a flexible interlayer 13 between the two partitions. The flexible interlayer 13 is made of elastic sponge material. Each limiting partition 12 has multiple circumferentially distributed and corresponding limiting holes 14. Each flexible interlayer 13 has multiple elastic stabilizing holes 15 corresponding to the limiting holes 14. The inner wall of each elastic stabilizing hole 15 protrudes inward to form a hole structure that is larger on the outside and smaller on the inside, so that the pipette can pass through the elastic stabilizing hole 15 and the inner wall of the elastic stabilizing hole 15 can tightly adhere to the inner wall of the pipette to prevent it from shaking. The water collection chamber 11 has an opening at the front. Inside the water collection chamber 11, there is a water collection trough 16 that can be pulled out from the front. After the pipette is cleaned, a small amount of water will still remain in the pipette. The water in the pipette drips into the water collection trough 16 after passing through the mesh drain plate 9, which can keep the pipette and the table dry. A horizontal second handle 17 is provided at the front of the water collection trough 16.

[0025] Instructions for use: When a pipette needs to be inserted, pull out the placement frame 2 and pass the pipette from top to bottom through the limiting hole 14 and the elastic stabilizing hole 15 of the two horizontal partitions. The inner wall of the elastic stabilizing hole 15 is squeezed and expands outward to allow the pipette to pass through. By clamping the inner wall of the pipette, the pipette is prevented from shaking when the placement frame 2 is moved. Then, put the placement frame 2 back into the cover 1. After the Hall effect sensor switch 7 senses the magnet 8 approaching, it controls the ultraviolet disinfection lamp 6 to perform timed ultraviolet disinfection. The water in the pipette drips through the mesh drain plate 9 and falls into the water collection tank 16 for storage. The water collection tank 16 can be pulled out and emptied periodically.

[0026] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

[0027] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
