Description
Technical Field
The utility model relates to the field of cell culture equipment, in particular to an arc-shaped electric pipette.
Background
In the cell culture process, an electric pipette is an indispensable experimental device, and in practical application, for example, when cell elution is carried out, a dead angle part which cannot be sucked by blowing exists at the mouth of a culture bottle of a traditional long straight pipette, so that the cell elution is not thorough; to solve the problems, the arc-shaped electric pipette is designed to solve the problems that dead angle parts in a culture vessel are difficult to blow and suck, cells are lost and the like by adopting an arc-shaped tip tube body to design and match with an inclined tube orifice, and the operation efficiency and the production efficiency are greatly improved.
Disclosure of Invention
The utility model aims to solve the defects of the conventional electric pipette and provides an arc-shaped electric pipette capable of reducing cell loss.
In order to achieve the above purpose, the following scheme is proposed:
an arc-shaped electric pipette comprises an arc-shaped tube body 1, wherein the lower end of the arc-shaped tube body is an inclined tube opening 2, and the upper end of the arc-shaped tube body is a connector 3 connected with an electric pipette; the arc-shaped pipe body is provided with two sets of scale marks 4.
Preferably, the arc-shaped pipe body is bent at the position of 1mL, and the angle is 30 degrees.
Preferably, the inclined pipe orifice has an inclination angle of 45 degrees.
Preferably, the two sets of graduation marks 4 are standard 5mL, 0.1mL is accurate, the maximum graduation is 7mL, and the two sets of graduation marks are divided into a forward graduation mark 5 and a reverse graduation mark 6.
Preferably, the arc-shaped pipe body is made of pure transparent polyvinyl chloride materials, and a filter cotton core 7 is arranged at the joint of the pipe body and the electric pipettor.
In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows: the utility model provides an arc-shaped electric pipette which solves the problems that dead corners of a culture bottle are difficult to blow and suck and liquid in a centrifuge tube is remained in the use process of a long straight type plain end pipette in the market at present; 1. the design of the arc-shaped tube body can simply treat dead angle positions of the culture bottle, avoid cell loss caused by incomplete cell elution, greatly save production cost and further accurately test data; 2. the design of the inclined pipe orifice is that the inclined pipe orifice is more attached to the wall of the centrifuge tube, so that a better liquid transfer effect is achieved, and cell loss caused by liquid residue is avoided; moreover, the utility model has simple structure and convenient operation, is suitable for large-scale batch production, and has great economic value.

Fig. 2 is a schematic view of a beveled nozzle of the present utility model.
In fig. 1: 1. the device comprises an arc-shaped pipe body 2, an inclined pipe orifice 3, a connector 4, two sets of scale marks 5, a forward scale mark 6, a reverse scale mark 7 and a filter cotton core.
Detailed Description
The present utility model will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, an arc-shaped electric pipette comprises an arc-shaped pipe body 1, wherein the arc-shaped pipe body is bent at 1mL, the angle is 30 degrees, and the dead angle part of a culture bottle can be blown and sucked due to the 30-degree design of the pipe body, so that the cell loss is reduced, the arc-shaped pipe body is made of pure and transparent polyvinyl chloride materials, the liquid level in the pipette can be clearly observed, and the quantitative measurement is convenient.
The lower end of the arc-shaped pipe body 1 is provided with an inclined pipe orifice 2, the inclined pipe orifice is designed at 45 degrees, and the inclined pipe orifice is perfectly attached to the wall of the centrifuge tube, so that cell loss caused by liquid residue is reduced.
The upper end of the arc-shaped pipe body 1 is provided with a connector 3 connected with the electric pipette, and the arc-shaped pipette connector is inserted into the electric pipette pipe sleeve for use when in use.
The arc-shaped pipe body 1 be provided with two sets of scale mark 4, two sets of scale mark standard 5mL, accurate to 0.1mL, maximum scale 7mL, two sets of scale mark divide into forward scale mark 5 and reverse scale mark 6, observe scale mark 5 numerical value from down to the positive number, observe scale mark 6 numerical value from top to bottom when arranging and beat liquid, it is directly perceived clearly, convenient operation.
The connector at the upper end of the arc-shaped pipe body 1 is internally provided with a filter cotton core 7, and the filter cotton core effectively prevents the cell suspension from being sucked into the electric pipette in a reverse way due to misoperation, thereby avoiding unnecessary instrument loss.
Finally, it should be noted that the above-mentioned embodiments are only for illustrating the preferred embodiments of the present utility model, and not for limiting the present utility model, and it is obvious to those skilled in the art that modifications may be made to the technical solutions described in the above-mentioned embodiments or equivalent substitutions may be made in some of them, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
