[0002] A multi-functional pipette tip holder is a device used in laboratory environments to store and protect pipette tips, widely applied in experimental operations in fields such as biology, chemistry, and medicine. As a core consumable of pipettes, the storage environment of pipette tips directly affects the accuracy and safety of experiments. Tip holders not only need to provide stable storage space but also must meet the high requirements of laboratories for cleanliness, sterility, and convenience. Traditional tip holders typically employ a fixed tray design, accommodating specific tip sizes and protecting the internal consumables with a simple lid structure. However, with the diversification of experimental needs and the increasing variety of tip sizes and types, traditional tip holders are gradually showing limitations in terms of flexibility, compatibility, and portability.

[0003] The existing pipette tip boxes have the following problems when used:

[0004] 1. Insufficient compatibility: The tray aperture and layout of traditional pipette tip boxes are fixed and cannot be adapted to various pipette tip sizes (such as 10μL, 200μL, 1000μL, etc.), which requires users to frequently change different models of pipette tip boxes, increasing experimental costs and operational complexity.

[0005] 2. Insufficient storage and portability: The trays of existing tube tip boxes are mostly fixed installations, which are difficult to disassemble or adjust. Moreover, the overall structure is relatively bulky, making it inconvenient to move between laboratories or store for a long time. The storage method of the trays is limited and takes up a lot of space.

[0006] Therefore, a multifunctional pipette tip box is needed to solve the above problems. Utility Model Content
