Description

Petri dishes for anaerobic environments

technical field

The utility model specifically relates to a culture dish used for making an anaerobic environment.

Background technique

A petri dish is a laboratory vessel used for microbial or cell culture, consisting of a flat disc-shaped bottom and a cover, generally made of glass or plastic. The materials of petri dishes are basically divided into two categories, mainly plastic and glass. Glass can be used for plant materials, microbial culture and animal cell adherent culture. The plastic ones may be made of polyethylene materials, and there are disposable and multiple-use ones, which are suitable for laboratory inoculation, streaking, and isolation of bacteria, and can be used for the cultivation of plant materials. However, we find some deficiencies during our daily use: for example, the existing petri dish has a relatively simple structure and simple functions, and cannot meet some cultivation processes with special requirements, such as anaerobic environment.

Contents of the invention

Aiming at the problems existing in the above-mentioned prior art, the utility model provides a petri dish for making an anaerobic environment.

In order to achieve the above object, the technical scheme adopted by the utility model is: a culture dish for making anaerobic environment, including a dish body; the outer surface of the dish is threaded with a first annular body with an L-shaped cross section; the first ring The outer surface of the shape is slidably connected with a first housing with an n-shaped cross section; The surface is also fixedly provided with an exhaust hole, and the exhaust hole is threadedly connected with a sealing plug.

Preferably, a hexagonal prism-shaped protrusion is vertically oriented on the lower surface of the dish body, and a first groove is vertically oriented on the central area of the main surface of the dish body.

Preferably, a sealing ring is provided in the middle of the outer surface of the first annular shape.

Preferably, a first annular protrusion is vertically oriented on the outer surface of the first casing.

Preferably, a silica gel pad is provided on the lower surface of the first annular body, and an annular groove is provided on the lower surface of the silica gel pad.

Preferably, the lower surface of the first housing is provided with a ring-shaped vertically oriented first counterbore, a first cylinder is slidably connected in the first counterbore, and the lower surface of the first cylinder is fixedly connected with the first annular body.

Compared with the prior art, the utility model has the advantages of:

1. The outer surface of the dish is threaded with a first annular body with an L-shaped cross-section to adjust the size of the space during the cultivation process, and at the same time provide preparation conditions for an anaerobic environment, and facilitate the insertion and removal of the cultivation;

2. The outer surface of the first ring is slidably connected with the first shell with an n-shaped cross section, which adjusts the size of the space during the cultivation process and prepares for providing an anaerobic environment;

3. At least two first ball valves are fixed on the main surface of the first shell, and the upper end of the first ball valve is fixedly connected with a suction pipe. When the upper surface of the dish is in contact with the inner surface of the first shell, the inner storage neps are the smallest and the oxygen content is the least. One suction pipe sucks out most of the remaining oxygen, and then fills it with nitrogen through the other suction pipe, so as to achieve anaerobic surroundings;

4. The overall design is novel, easy to disassemble and install, and it is convenient to create an anaerobic environment.

Description of drawings

Fig. 1 is the structure schematic diagram that the utility model is used for making the petri dish of anaerobic environment.

Detailed ways

The utility model will be further described below in conjunction with accompanying drawing.

As shown in Fig. 1, a kind of petri dish for making anaerobic environment comprises dish body 3; The outer surface of dish body 3 is threadedly connected with the first annular body 2 that section is L-shaped, regulates the space size in the cultivation process, simultaneously Prepare conditions for providing an anaerobic environment, and facilitate the putting in and taking out of the culture; the outer surface of the first annular body 2 is slidingly connected with the first shell 1 with an n-shaped cross section to adjust the size of the space during the culture process, and at the same time Make preparations for providing an anaerobic environment; and, the main surface of the first casing 1 is fixedly provided with at least two first ball valves 5, and the upper end of the first ball valves 5 is screwed and fixedly connected with a suction pipe 6, and the main surface of the first casing 1 is also fixed. A vent hole is fixed, and the vent hole is threadedly connected with a sealing plug 4. When the upper surface of the dish body 3 is in contact with the inner surface of the first shell 1, the internal storage neps are the smallest, and the oxygen content is the least. A suction pipe 6 will remove the remaining Most of the oxygen is sucked out, and then filled with nitrogen through another suction pipe 6, thereby realizing an anaerobic environment. The lower surface of the dish body 3 is vertically oriented with hexagonal prism protrusions, and the central area of the main surface of the dish body 3 is vertically oriented with a first groove. A sealing ring is provided in the middle of the outer surface of the first annular body 2 . A first annular protrusion 11 is vertically oriented on the outer surface of the first casing 1 . The lower surface of the first annular body 2 is provided with a silica gel pad, and the lower surface of the silica gel pad is provided with an annular groove. The lower surface of the first casing 1 is circularly and vertically provided with a first counterbore, and a first cylinder is slidably connected in the first counterbore, and the lower surface of the first cylinder is fixedly connected with the first annular body 2 .

It can be seen from FIG. 1 that the outer surface of the first housing 1 may be provided with anti-collision strips to avoid impact damage. In one embodiment, as shown in Fig. 1, at least two first ball valves 5 are fixed on the main surface of the first housing 1, and the upper ends of the first ball valves 5 are screwed and fixedly connected with a suction pipe 6, and the main surface of the first housing 1 is also fixed. There is a vent hole, and the vent hole is threadedly connected with a sealing plug 4. When the upper surface of the dish body 3 is in contact with the inner surface of the first shell 1, the inner storage neps are the smallest, and the oxygen content is the least. Part of the oxygen is sucked out.

Therefore, the present invention will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
