[0002] The pipette is a tool used in the laboratory to accurately transfer liquids, and the pipette tip is its key accessory. The pipette tip box is a common auxiliary equipment used to store pipette tips. The design of the pipette tip box directly affects the storage and retrieval efficiency of the tips, as well as the convenience and accuracy of experimental operations.

[0003] Currently, the design of traditional pipette tip boxes on the market has limitations. First, the fixed design has a single specification and can only store pipette tips of a specific size. For laboratories that require tips of various specifications, this design is not flexible enough. Second, the space utilization rate is low. The fixed specification design may lead to low space utilization, especially when it is necessary to store tips of various specifications. Third, there is no integrated function. Traditional pipette tip boxes usually do not have other functions, such as a bracket function, and additional equipment is required to place the pipette. When using it, the phenomenon of "gun looking for the tip" or "tip looking for the gun" often occurs, wasting time and energy.

[0004] Therefore, it is necessary to design a combined pipette tip box with multi-specification pipette tip placement holes and a pipette placement rack. Summary of the invention

[0005] In order to solve the above technical problems, the utility model proposes a combined pipette tip box, including a pipette tip placement box and a pipette gun placement rack, wherein a modular design is added to realize flexible combination and expansion of the pipette tip placement box, and the pipette tip placement box is detachably combined with the pipette gun placement rack, thereby improving space utilization and work efficiency.

[0006] The technical solution of the utility model is: a combined pipette tip box, including a detachably connected pipette tip placement box and a pipette gun placement rack, the pipette tip placement box is provided with a plurality of detachably connected sub-area boxes, the sub-area boxes are provided with a plurality of spaced circular holes for placing the gun tips, the circular holes of different sub-area boxes have different sizes to place pipette gun tips of different specifications, the outer wall of the sub-area box is provided with a slide groove and a slider adapted to the slide groove, adjacent sub-area boxes are detachably connected through the slide groove and the slider, the pipette gun placement rack is also provided with a slide groove or a slider so that the sub-area box and the pipette gun placement rack can be detachably connected.

[0007] Preferably, the slide grooves are symmetrically arranged on the front and rear sides of the sub-area box, and the sliders are symmetrically arranged on the left and right sides of the sub-area box.

[0008] Preferably, the slide grooves are arranged at intervals on two adjacent sides of the sub-area box, the sliders are arranged at intervals on two adjacent sides of the sub-area box, and the slide grooves are arranged opposite to the sliders.

[0009] Preferably, the sub-area box can be a collection bucket for collecting discarded pipette tips.

[0010] Preferably, a plurality of slide grooves or sliders are provided on the left side surface of the pipette placement rack.

[0011] Preferably, the pipette placement rack is provided with an inclined surface, the angle between the inclined surface and the horizontal plane is between 45° and 60°, and a waste liquid tank is provided at the bottom of the inclined surface.

[0012] Preferably, a bracket is provided on the right side of the pipette placement rack, and the bracket is provided with a placement hole. During the experiment, the pipette tip that has been used and will be used again later can be placed in the placement hole on the bracket to avoid waste.

[0013] Preferably, the slide groove is any one of a T-shaped groove, a U-shaped groove, an L-shaped groove, a dovetail groove, and a trapezoidal groove.

[0014] Preferably, the top of the pipette tip placement box is provided with a box cover that is compatible with the sub-area box, and the bottom of the box is provided with a base that is compatible with the sub-area box.

[0016] (1) Use detachable pipette tip boxes and pipette gun racks to save space. Integrate the pipette tip boxes and pipette gun racks into a modular system to reduce the number of independent devices, thereby saving space on the laboratory bench.

[0017] (2) Use a modular pipette tip box to improve efficiency. The integrated design makes the pipette and the tip within easy reach, reducing the time spent moving and searching during experimental operations and improving work efficiency.

[0018] (3) The system uses several detachably connected sub-area boxes, which are flexible and expandable. The modular design can be flexibly combined and expanded according to experimental requirements. For example, modules can be added or reduced to accommodate different numbers and specifications of pipette tips and pipettes. BRIEF DESCRIPTION OF THE DRAWINGS

The pipette tip placement box 1 is provided with a plurality of detachably connected sub-area boxes, and the sub-area boxes are provided with a plurality of spaced circular holes for placing the tips. The circular holes of different sub-area boxes have different sizes to match the tips of different specifications. Figure 1 , Figure 2 The sub-area box without a circular hole is a collection bucket for collecting discarded gun tips. The existence of the collection bucket prevents the discarded gun tips from polluting the environment and also facilitates the recycling and reuse of the gun tips.

[0028] like Figure 3 As shown, in Example 1, a slide groove 101 is provided on the left and rear edges of the outer wall of each sub-area box, and a slider 102 adapted to the slide groove 101 is provided on the front and right edges. The length of the slide groove 101 is equal to the length of the side edge of the sub-area box, and adjacent sub-area boxes are detachably connected through the slide groove 101 and the slider 102.

A bracket 201 is provided on the right side of the pipette placement rack 2, and a placement hole with the same aperture as the circular hole on the sub-area box is provided on the bracket 201. During the experiment, the used gun tip that will be used later can be placed in the placement hole on the bracket 201 to avoid waste.

[0030] Optionally, in some embodiments, the position of the chute 101 on the sub-area box can also be symmetrically arranged on the left and right sides of the sub-area box, and the corresponding slider 102 adapted to the chute 101 is also symmetrically arranged on the front and rear sides of the sub-area box. The specific positions of the chute 101 and the slider 102 can be on the edge of each face, or in the middle of each face, and multiple chute 101 or slider 102 can be arranged on each face. One or more chute 101 or slider 102 can also be arranged on the left side of the pipette gun placement rack 2, so that the combination of the sub-area box and the pipette gun placement rack 2 can be changed according to the current laboratory environment and needs when in use.

[0031] Optionally, in some embodiments, a box cover adapted to the sub-area box is provided on the top of the pipette tip placement box 1, and a base adapted to the sub-area box is provided on the bottom thereof, and the box cover and the base have a fixing function to prevent sliding between the slide groove 101 and the slider 102 when the pipette tip box 1 is moved.

[0032] In summary, the combined pipette tip box provided by the utility model can be flexibly combined and expanded according to experimental requirements, thereby improving space utilization and work efficiency.
