Description

Technical Field

[0001] The utility model belongs to the technical field of medical experimental instruments, and particularly relates to a combined pipette. Background Art

[0002] A pipette, also known as a micropipettor or dispenser, is a commonly used laboratory tool in biology, chemistry, and medical experiments. It is mainly used to accurately measure, transfer, and dispense trace amounts of liquid, which is crucial for the success of many experiments.

[0003] For example, a Chinese patent with the publication number CN209237983U discloses a pipette, which includes a pipette body, a pipette tip, and a sealing and leak-proof device; the sealing and leak-proof device includes a housing, a sealing pull ring, an elastic sealing ring, and a spring block; the housing is sleeved on the suction end of the pipette body and is fixedly connected to the suction end of the pipette body. The housing is provided with a first hole group and a second hole group from top to bottom in sequence.

[0004] Although the above-mentioned disclosed patent solves the problem of poor sealing between the pipette body and the pipette tip, there are still some defects in the existing pipettes that need to be improved. When the pipette is in a non-use state, the protruding finger hook not only poses a potential safety hazard, is easy to accidentally scratch with foreign objects, causing unnecessary damage, but also limits the convenient storage of the pipette when not in use. In addition, after the pipette completes its work, in order to drain the residual liquid inside, it often needs to rely on an additional hanging rack for hanging, which is very inconvenient to operate, and the hanging rack is relatively large in size and also occupies the laboratory table space.
