Problems solved by technology

[0002] The existing pipette has a simple structure and cannot control the amount of discharge each time when moving the solution, which causes trouble for some required experiments and limits the use of the pipette. At the same time, most of the pipettes are straight Tube, the shortcoming of the straight tube facing the corner has not been overcome

Embodiment Construction

[0008] Such as figure 1 As shown, a pipette includes a tube body 1, a straight-through control switch 3 is arranged on the upper part of the tube body 1, a scale line is set on the outer wall of the tube body 1, and a tip 2 is bent to one side at the lower end of the tube body 1. When in use, the straight-through control switch 3 can be used to control the amount of liquid that flows out each time. The tip 2 at the lower end of the tube body 1 narrows the nozzle, stabilizes the flow rate, and makes up for the shortcoming that the straight tube cannot face the corner.

[0009] An embodiment of the present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention, and cannot be considered as limiting the implementation scope of the present invention. All equivalent changes and improvements made according to the application scope of the present invention shall still belong to the scope covered by the patent of ...

Abstract

The present invention relates to a pipette, which comprises a pipe body, and is characterized in that the upper portion of the pipe body is provided with a straight-through type control switch, the outer wall of the pipe body is provided with scale lines, and the lower end of the pipe body is the tip end and bends toward one side. According to the present invention, the each amount of the outflow liquid can be controlled by adopting the straight-through type control switch according to the requirement, and the tip end on the lower end of the pipe body makes the pipe opening narrow so as to stabilize the flow rate and overcome the disadvantage of incapability of alignment to the corner of the straight pipe.

Description

technical field [0001] The invention relates to a pipette. Background technique [0002] The existing pipettes have a simple structure and cannot control the amount of discharge each time when moving the solution, which causes trouble for some demanding experiments and limits the use of pipettes. At the same time, most pipettes are straight Tube, the shortcoming of the straight tube facing the corner has not been overcome. Contents of the invention [0003] The object of the present invention is to provide a pipette that is simple and practical, has low cost, controls the discharge volume, and can face the corner. [0004] The technical solution of the present invention is: comprising a pipe body, a straight-through control switch is arranged on the upper part of the pipe body, a scale line is arranged on the outer wall of the pipe body, and the lower end of the pipe body is pointed and bent to one side. [0005] The advantages and positive effects of the present inventi...
