The pipette is one kind of pipettor, is commonly used in the laboratory to the removal of a small amount of or trace liquid, and the specification is different, and the pipette of different specifications matches and uses the rifle head of different sizes, and the shape of different manufacturers' production is also slightly different, but theory of operation and operating method are unanimous basically. A liquid-transferring gun is commonly used in the fields of biology, medical treatment, chemistry and the like, belongs to a precise instrument, and needs to be careful when in use and storage so as to prevent damage and avoid influencing the measuring range. The pipette tip is a disposable consumable which consumes a lot of money when being matched with the pipette tip, and the pipette tip box is a common portable plastic box for storing the pipette tip.

When the existing pipetting gun head box is used, a pipetting gun head support is easily lifted due to friction force between the pipetting gun head support and the pipette head, so that the pipetting gun head is scattered, poor in sealing performance and difficult to keep sterile in the biological field. Through the problems found in the experimental process, the following defects are summarized: (1) the sealing property is poor. When the pipette is used in an aseptic grade A clean area, the unsealed pipette head box is easy to gather fungi and cannot meet the aseptic operation; and (2) a gun head bracket in the liquid-transferring gun box is not fixed. The pipette tip support is not fixed, and when the pipette tip is used for taking, the friction force between the pipette tip and the pipette tip support enables the pipette tip support to shake or lift up along with the pipette tip, so that the mounted pipette tip can be overturned. Therefore, the application provides a sealed pipette tip cartridge for securing a tip holder that meets the requirements.
