[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0021] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a pipetting device includes a base 1, on which a pipette placement area 2, a pipette tip storage area 3, and a centrifuge tube storage area 4 are provided. The pipette placement area 2 is located at the rear end of one side of the base 1 for suspending and placing pipettes. The centrifuge tube storage area 4 is located at the front end of the pipette placement area 2 for collecting and placing centrifuge tubes. The pipette tip storage area 3 is located on the other side of the base 1 for collecting and placing pipette tips.

[0022] This invention proposes a pipetting device. The base 1 is divided into three functional areas: a pipette placement area 2, a tip storage area 3, and a centrifuge tube storage area 4. The pipette placement area 2 is located at the rear end of one side of the base 1, and its function is to suspend and place pipettes, providing a dedicated storage location for easy access and storage. The centrifuge tube storage area 4 is located at the front end of the pipette placement area 2, and its main function is to collect and store centrifuge tubes, facilitating their organization and storage during pipetting operations. The tip storage area 3 is located on the other side of the base 1, specifically for collecting and placing pipette tips, providing an orderly storage space for them.

[0023] This pipetting device primarily assists in pipetting operations through the rational arrangement of its various components. In actual use, operators can select appropriate pipette tips from the tip storage area 3 and attach them to the pipette (placed in the pipette storage area 2). They then use the pipette to draw up the medication and transfer it to centrifuge tubes in the centrifuge tube storage area 4. The entire device, by dividing the storage area into different zones, allows for the orderly storage of components involved in the pipetting process, such as pipettes, tips, and centrifuge tubes, making it convenient for operators to quickly find the required items and improving the efficiency and standardization of pipetting operations.

[0024] Combination Figure 1 , Figure 2 and Figure 4 As shown, the centrifuge tube storage area 4 includes a placement rack 41 set on the base 1, a placement plate 42 is set on the top of the placement rack 41, and placement holes 43 are arranged in a matrix on the placement plate 42.

[0025] Specifically, the centrifuge tube storage area 4 is a dedicated area for storing centrifuge tubes. The placement rack 41 is fixedly mounted on the base 1, serving to support the other components of the entire centrifuge tube storage area 4 and providing a stable framework for the placement of centrifuge tubes.

[0026] The placement plate 42 is mounted on top of the placement rack 41 and is the component that directly supports the centrifuge tubes. It provides a flat placement surface for the centrifuge tubes, ensuring that the centrifuge tubes can be placed stably.

[0027] Placement holes 43 are formed on the placement plate 42 and arranged in a matrix. These placement holes 43 are specifically designed for centrifuge tubes, and their size and shape match the centrifuge tubes, allowing the centrifuge tubes to be accurately inserted and stored in an orderly and neat manner. The matrix arrangement ensures that the centrifuge tubes are evenly distributed on the placement plate 42, making it easy for operators to quickly find the required centrifuge tubes, while also improving space utilization.

[0028] During use, the operator inserts centrifuge tubes one by one into the placement holes 43 on the placement plate 42. Because the placement holes 43 are arranged in a matrix, the centrifuge tubes are neatly arranged on the placement plate 42 according to a certain pattern. When a centrifuge tube needs to be retrieved, the operator can quickly locate and retrieve the required centrifuge tube based on its position in the matrix. This effectively stores and manages the centrifuge tubes, avoiding the chaos and damage caused by haphazard placement, and improving the efficiency and accuracy of experimental operations. At the same time, the placement rack 41 provides stable support for the entire storage area, ensuring that the placement plate 42 and centrifuge tubes do not shake or tip over during the process of retrieving and placing the centrifuge tubes.

[0029] Combination Figure 1 , Figure 2 and Figure 4 As shown, the diameter of the hole 43 is set to different sizes according to the size of the centrifuge tube.

[0030] Specifically, in practical use, this design, which sets different diameter placement holes 43 according to the size of the centrifuge tubes, fully leverages its functions of precise storage and efficient management. When operators need to store centrifuge tubes, they can select the placement hole 43 that matches the outer diameter of the centrifuge tube. Smaller centrifuge tubes can be easily inserted into the smaller diameter placement hole 43 for stable placement; while larger centrifuge tubes are inserted into the larger diameter placement hole 43 to ensure tightness and stability.

[0031] This effectively avoids many problems caused by a single aperture size. If the aperture is uniform and too large, small centrifuge tubes will wobble after being placed in it, increasing the risk of damage and making it difficult to fix their position; if the aperture is uniform and too small, large centrifuge tubes cannot be placed in it. The different aperture sizes ensure that centrifuge tubes of various sizes can find a suitable place, not only ensuring the safety of the centrifuge tubes during storage and preventing damage or collisions due to shaking, but also greatly facilitating operators to quickly and accurately retrieve the required centrifuge tubes. During experiments, operators do not need to spend a lot of time searching for the appropriate aperture size to place or retrieve centrifuge tubes, improving experimental efficiency and making the entire centrifuge tube storage area 4 neater and more organized, improving the laboratory's space utilization and management level.

[0032] Combination Figure 1 , Figure 2 and Figure 4 As shown, an anti-slip pad 5 is provided between the bottom of the placement rack 41 and the base 1.

[0033] Specifically, the rack 41 stands vertically on the base 1, providing a stable frame for the entire storage area; the plate 42 is horizontally fixed to the top of the rack 41, serving as the direct support platform for the centrifuge tubes; the holes 43 are regularly spaced on the plate 42, with different diameters designed according to the size of the centrifuge tubes to meet the storage needs of various centrifuge tubes. The anti-slip pad 5 is located between the bottom of the rack 41 and the base 1, fitting snugly against the bottom surface of the rack 41 while also making full contact with the upper surface of the base 1.

[0034] The anti-slip mat 5 is typically made of a material with a high coefficient of friction, such as rubber. When the rack 41 is placed on the base 1, the anti-slip mat 5, due to its material properties, increases the friction between the bottom of the rack 41 and the base 1. In daily laboratory operations, external forces may arise that cause the rack 41 to slide relative to the base 1, such as personnel movement, equipment vibration, or slight contact with the rack 41. However, the strong friction provided by the anti-slip mat 5 effectively resists these external forces, preventing the rack 41 from sliding freely on the base 1, thereby ensuring the stability of the entire centrifuge tube storage area 4.

[0035] Combination Figure 1 , Figure 2 and Figure 3 As shown, the pipette placement area 2 includes a fixing frame 21 mounted on the base 1, an inclined fixing plate 22 mounted on the fixing frame 21, and several equidistant placement rings 23 arranged side by side on the fixing plate 22.

[0036] Specifically, the pipette placement area 2 is a specific area within the entire pipetting apparatus used to store pipettes. The mounting bracket 21 is the basic support structure of the pipette placement area 2, securely mounted on the base 1. It serves to support and secure other components, providing a stable framework for the entire placement area and ensuring the safety and stability of pipette placement.

[0037] The mounting plate 22 is mounted on the mounting bracket 21 and is tilted. The tilted mounting plate 22 facilitates the operator's handling and placement of pipettes. The tilted mounting plate 22 provides a specific placement angle for the pipettes, making placement more natural and convenient.

[0038] Placement rings 23 are arranged side-by-side at equal intervals on the fixing plate 22. These placement rings 23 are the parts that directly contact the pipette, and their shape and size match the outer contour of the pipette, thus securing the pipette and preventing it from shaking or slipping during placement. The equidistant arrangement ensures that each pipette has an independent and fixed placement position, making it easy for operators to quickly find the required pipette, while also making the entire placement area look neat and orderly.

[0039] In practical use, the working principle of the pipette placement area 2 is mainly based on its reasonable structural design to effectively store and manage pipettes: after the operator completes the pipetting operation, the pipette is inserted into the placement ring 23 on the fixing plate 22 in sequence. Due to the tight fit between the placement ring 23 and the pipette, the pipette can be firmly fixed in the placement ring 23. At the same time, the inclined design of the fixing plate 22 makes the pipette present a certain tilt angle after placement, which not only prevents the liquid in the pipette from flowing back into the pipette, but also makes it convenient for the operator to quickly pick it up for the next use.

[0040] When a pipette is needed, the operator can directly retrieve the required pipette from the corresponding placement ring 23 according to the type of pipette or usage habits. Since the placement rings 23 are evenly spaced, the operator can easily locate the target pipette without spending a lot of time searching, greatly improving work efficiency.

[0041] Combination Figure 1 , Figure 2 and Figure 3 As shown, the inclined surface of the fixing plate 22 is provided with anti-slip texture.

[0042] Specifically, the fixing plate 22 has an inclined surface, and anti-slip textures are specially provided on this inclined surface. These anti-slip textures can be regular stripes, grids, or irregular combinations of protrusions and depressions, evenly distributed on the inclined surface of the fixing plate 22, increasing the surface roughness.

[0043] When the pipette is placed in the placement ring 23 of the fixing plate 22, the pipette will have some contact with the inclined surface of the fixing plate 22. The presence of the anti-slip texture greatly increases the friction between the pipette and the surface of the fixing plate 22. Under normal circumstances, because the fixing plate 22 is inclined, the pipette will be subject to gravity and tend to slide downwards along the inclined surface. However, the friction generated by the anti-slip texture can effectively resist this downward tendency, keeping the pipette firmly in the placement ring 23 and preventing it from easily slipping off, thus ensuring the safety of the pipette placement and avoiding damage caused by the pipette slipping off.

[0044] Combination Figure 1 , Figure 2 and Figure 5 As shown, the suction head storage area 3 includes a placement box 31 set on the base 1. The top of the placement box 31 is provided with a transparent dust cover 32. Several suction head placement holes 33 are arranged in a matrix inside the placement box 31.

[0045] Specifically, the pipette tip storage area 3 is a dedicated area for storing pipette tips within the pipetting device. It is entirely built on the base 1, with the placement box 31 set on the base 1. This provides a relatively independent and enclosed storage space for the pipette tips, effectively protecting them from external environmental interference and impacts.

[0046] A transparent dust cover 32 is installed on the top of the placement box 31 and is made of transparent material. It allows operators to directly observe the number, type, and usage of the suction heads inside the placement box 31 without opening the dust cover, while also preventing dust and impurities from falling into the placement box 31 and contaminating the suction heads, thus ensuring the cleanliness of the suction heads.

[0047] Inside the storage box 31, several nozzle placement holes 33 are arranged in a matrix. The shape and size of these nozzle placement holes 33 match the outer contour of the nozzle, allowing the nozzle to be accurately inserted and stored in an orderly and neat manner. The matrix arrangement ensures that the nozzles are evenly distributed within the storage box 31, making it easy for operators to quickly find the required nozzle, while also improving space utilization.

[0048] When researchers finish using the suction tips or need to prepare them in advance, they insert the tips one by one into the tip placement holes 33 inside the placement box 31. Since the tip placement holes 33 are arranged in a matrix, the tips will be neatly arranged in the placement box 31 according to a certain pattern. The transparent dust cover 32 is in the closed state, preventing external dust and impurities from entering the placement box 31 and keeping the tips clean. At the same time, the placement box 31 provides a stable storage environment for the tips, avoiding the chaos and damage caused by haphazard placement.

[0049] When a nozzle is needed, the operator can observe the distribution of nozzles in the storage box 31 through the transparent dust cover 32 to quickly locate the required nozzle. Then, the transparent dust cover 32 is opened, and the nozzle is removed from the corresponding nozzle placement hole 33. Due to the precise design of the nozzle placement hole 33, the nozzle can be easily removed without affecting the position of other nozzles. After use, the transparent dust cover 32 is closed again to continue protecting the remaining nozzles.

[0050] Combination Figure 1 , Figure 2 and Figure 5 As shown, a label area 6 is provided on the placement box 31, and labels are pasted below all the suction head placement holes 33.

[0051] Specifically, label area 6 is located on the placement box 31 and is a dedicated labeling area. Its prominent position makes it easy for operators to see and identify. A label is affixed below each nozzle placement hole 33, and these labels correspond to information such as the nozzle type and specifications.

[0052] When placing the nozzles into the nozzle storage area 3, the experimenters inserted them into the corresponding nozzle placement holes 33 according to their specific type and specifications. Each nozzle placement hole 33 has a label attached below it, acting like an "identity card" to clearly indicate which nozzle should be placed in that hole. The experimenters can quickly and accurately return the nozzles to their correct positions based on the label information, avoiding the chaos caused by random placement and ensuring orderly storage. Meanwhile, the placement box 31 provides a stable storage environment for the nozzles, while the transparent dust cover 32 prevents dust and other contaminants from entering, protecting the cleanliness and performance of the nozzles.

[0053] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
