Description
Technical Field
The utility model relates to a chemical experiment equipment technical field, especially a liquid-transfering gun head for airtight system application of sample.
Background
As is known, in the experimental study of chemical reaction, the environment without water and oxygen is often required to be achieved, and in the prior art, a reaction system is often vacuumized and then protected by inert gas, and then corresponding reaction materials are added into a closed system without water and oxygen; the syringe is a common laboratory-used liquid measuring tool, and a metal needle is adopted to add a sample to a closed system. However, the existing syringe is often difficult to successfully measure the required sample amount at one time during sampling, and usually a small amount of liquid is removed after being removed, so that the experimental efficiency is greatly reduced, the medicine is wasted, the environment is polluted, and meanwhile, the measuring precision is not high and the repeatability is poor.
The liquid-transferring gun can be used for measuring trace liquid, and has the advantages of high accuracy, convenient measurement and simple operation; however, most of the pipette tips in the market are made of plastic materials, and liquid cannot be fed into a closed system in a drilling mode.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that, overcome prior art's shortcoming, provide a liquid-transfering gun head for airtight system application of sample.
In order to solve the technical problem, the utility model provides a liquid-transfering gun head for sample application of a closed system, which is an integrated structure and comprises a liquid-transfering gun head main body which is an inverted cone frustum structure;
the smaller end of the pipette head main body is a pipette head liquid suction head which is integrally formed with the pipette head main body;
the great one end of liquid-transfering gun head main part extends along the axis direction of liquid-transfering gun head main part and forms liquid-transfering gun head mounting port, and liquid-transfering gun head mounting port is cylindrical structure.
The utility model discloses the technical scheme who further injects is:
further, in the pipette tip for sample application of the closed system, the outer surface of the mounting opening of the pipette tip is provided with a thread structure.
In the pipette tip for closed system sample application, the pipette tip main body, the pipette tip suction head and the pipette tip mounting opening are all made of plastic.
The technical effects are as follows: compared with the prior art, the precision of the instrument cannot be reduced when the pipette tip is used independently, and when the pipette tip is matched with a needle head of a conventional injector, a hole can be drilled to convey liquid into a closed system, so that the problems of poor precision, medicine waste, environment pollution, time consumption and the like when the injector is used are avoided while the use is convenient; furthermore, the utility model discloses the pipette tip has simple structure, simple to operate, low cost's advantage.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings based on these drawings without inventive exercise.
Fig. 1 is a schematic structural view of a pipette tip designed by the present invention;
FIG. 2 is a schematic view of the present invention in combination with a conventional syringe needle;
in the figure: the method comprises the following steps of 1-mounting a pipette head, 2-a pipette head main body, 3-a pipette head liquid suction head and 4-a traditional syringe needle.
Detailed Description
In order that the present invention may be more readily and clearly understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
Example 1
The structure of the pipette tip for sample application of a closed system is shown in fig. 1 and fig. 2, the pipette tip provided in this embodiment is an integrally formed structure, and includes a pipette tip main body 2, and the pipette tip main body 2 is an inverted truncated cone structure;
the smaller end of the pipette head main body 2 is provided with a pipette head liquid suction head 3, and the pipette head liquid suction head 3 and the pipette head main body 2 are integrally formed;
the larger end of the pipette tip main body 2 extends along the central axis direction of the pipette tip main body 2 to form a pipette tip mounting opening 1, and the pipette tip mounting opening 1 is of a cylindrical structure; further, the outer surface of the pipette tip mounting port 1 is provided with a thread structure, and meanwhile, the pipette tip is integrally made of plastic materials, so that the cost is low.
When the device is used in a concrete operation, the traditional syringe needle 4 is pushed to be tightly attached to the pipette head liquid suction head 3 only by pressing, so that the device is convenient to use, and the problems of poor precision, medicine waste, environment pollution, time consumption and the like when the syringe is used are avoided; furthermore, the utility model discloses the liquid-transfering gun head has simple structure, simple to operate.
Above embodiment only is for explaining the utility model discloses a technical thought can not be injectd with this the utility model discloses a protection scope, all according to the utility model provides a technical thought, any change of doing on technical scheme basis all falls into the utility model discloses within the protection scope.
