Description

Rapid arranging and storing box for pipette heads of liquid-transfering gun and using method

Technical Field

The invention relates to the technical field of tools for containing pipette tips of liquid-transfering guns, in particular to a storage box for quickly arranging pipette tips of a liquid-transfering gun and a using method of the storage box.

Background

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. The liquid-transfering gun belongs to a precise instrument, and is carefully used and stored, so that damage is prevented, and the measuring range is prevented from being influenced. Wherein the liquid-transfering gun rifle head is mostly disposable, needs in time to change after the use, and the liquid-transfering gun rifle head generally need be stored with the receiver.

However, when the existing collection box for the pipette head of the pipette is used, the whole box cover needs to be opened to take the pipette head, because the unused gun head is completely exposed to the outside when the box cover is opened, the gun head is easily polluted by impurities in the experimental environment, so that the subsequent use precision of the gun head is poor, secondly, the existing collection box for the pipette tips of the pipette can only store the pipette tips with specific sizes when in use, and because the pipette tips adopt a hollow tubular structure, the liquid transferring gun head collecting box is easy to deform due to extrusion in the storage process, the storage quality of the gun head is reduced, moreover, the existing liquid transferring gun head collecting box can only be used for storing the gun head, so that after the gun head is used, can not be rapidly collected, the residual liquid in the gun head can flow out due to the disordered arrangement of the gun head, and then pollute the workstation, reduced the treatment effeciency of liquid-transfering gun rifle head, consequently urgently needed a neotype liquid-transfering gun rifle head to arrange the receiver fast and solve current problem.
