Background art:

the inoculating needle and inoculating loop are commonly used inoculating tools in bacterial culture, and are widely applied to the fields of various subjects such as microbial detection, cell microbes, molecular biology and the like.

In the operation of microorganism experiment, the microorganism is often required to be picked by using an inoculating needle or an inoculating loop, however, the conventional inoculating loop in the prior art has the following two problems: (1) the prior inoculating loop has to be sterilized by an alcohol lamp after the previous operation, and the next operation can be carried out after the tungsten filament on the inoculating loop is sufficiently cooled after the sterilization, however, the process is extremely inconvenient and wastes time when the operation amount is large. (2) The existing inoculating loop may cause the problems of mixed bacteria pollution and the like due to the fact that the existing inoculating loop is short in sterilization time on an alcohol lamp, and the accuracy of a test result is affected.

A petri dish is a laboratory vessel for the cultivation of microorganisms or cells, consisting of a flat disc-shaped bottom and a lid, generally made of glass or plastic. In the microorganism experiment, a culture dish is also often needed, and in the separation and screening process of microorganisms, only one kind of separated bacteria is often placed in a culture medium, so that the waste of the culture medium and the space of the culture dish is caused. Meanwhile, in a plate confrontation experiment of microorganisms, the positions of the microorganisms and the circle center, a bacteriostatic zone and the like are often measured, but a culture dish in the prior art cannot be directly obtained, measurement must be carried out by other means, and the problems of errors, inconvenience and the like exist. In order to overcome the above problems, there is a need for an improved docking ring and culture dish based on the prior art.

The invention content is as follows:

the technical problem to be solved is as follows:

to prior art not enough, the utility model provides a household utensils combination for microbiological operation, inoculation pen possess need not wait for after the inoculation utensil sterilization, but continuous operation's advantage, the culture dish possesses space make full use of, can directly obtain basic data's advantage. The problems that the inoculation process by using an inoculation instrument consumes long time, pollutes sundry bacteria, and the space of a culture dish is not fully utilized and the measurement is not convenient are solved.

The technical scheme is as follows:

the utility model aims to provide a household utensils combination for microbiological operation to solve the problem that proposes to exist among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a vessel combination for microbiological operation, comprising a inoculation pen and a culture vessel, characterized in that: the inoculation pen includes: the pen comprises a pen body, a pen opening, a piston, a threaded rod, a pen cap and a sponge block, wherein the piston is arranged in the pen body, the upper part of the piston is fixedly connected with the bottom of the threaded rod, the upper part of the threaded rod is fixedly connected with the pen cap, and the sponge block is arranged at the pen opening; the culture dish comprises: a coordinate system and grid lines. (ii) a And the culture dish is provided with a coordinate system and grid line marks.

Preferably, the diameter of the pen mouth of the inoculation pen is 1.5 mm-3 mm.

Preferably, the whole material of the inoculation pen is a heat-resistant material with better hardness, such as PP and PE.

Preferably, the bottom surface of the culture dish (2) takes the circle center as the origin, and is provided with a rectangular coordinate system distributed in an X axis and a Y axis, and scale marks are formed on the coordinate axis. The scale lines are accurate to millimeters.

Preferably, grid lines are distributed on the bottom surface of the culture dish (2), 2-4 grid lines are respectively arranged on the X axis and the Y axis, and the grid lines are equidistant.

Preferably, the scale marks at the bottom of the glass culture dish are made of heat-resistant materials.

Has the advantages that:

according to the vessel combination for microbial operation, the bacteria inoculation pen can insert the toothpick into the pen opening for one-time operation such as separation, purification, inoculation and the like through the arrangement of the pen body, the pen opening, the piston, the threaded rod, the pen cap and the sponge block, the toothpick is knocked out by the piston in the pen body after the operation is finished, the toothpick is continuously inserted into the pen cap for repeated operation, and the process that the inoculation device needs to be sterilized and fully cooled after one-time operation is removed. Grid lines are distributed at the bottom of the culture dish, so that separated bacteria can be spotted in each grid, and the space of the culture dish and the nutrition of a culture medium are fully utilized; the culture dish bottom is provided with the rectangular coordinate system of taking the scale, can directly acquire data such as the concrete distribution condition of bacterium, antibacterial zone length, antibacterial zone size, very big improvement the convenient degree of microorganism operation.
