Description

a microbial petri dish

Technical Field

The utility model relates to the technical field of petri dishes, specifically a microbial petri dish.

Background technique

Anaerobic microorganisms are an important group of marine microorganisms. The vast majority of anaerobic microorganisms are bacteria, a few are actinomycetes, and a very few are mycoplasma. Anaerobic bacteria are a type of bacteria that grow under anaerobic conditions, especially Strictly anaerobic bacteria are extremely susceptible to oxygen poisoning due to the lack of superoxide dismutase, and even brief exposure to air can cause damage and even death.

The study of anaerobic microorganisms is of great significance to the study of marine microorganisms, but in the process of cultivating anaerobic microorganisms, it is necessary to use microbial petri dishes. The traditional petri dish is composed of a round lid and a dish body. This kind of petri dish When opening, your fingers will come into contact with the inside of the dish cover, causing the microbial petri dish to be contaminated during the culture process. Moreover, the sealing of the petri dish with this structure is poor, which affects the cultivation of anaerobic microorganisms in the petri dish. Therefore, we propose a microbial petri dish.

The utility model will be further described below in conjunction with the examples.

A microbial culture dish in this embodiment, as shown in Figures 1-5, includes a dish body 1 and a dish cover 2 that is detachably provided on the dish body 1. The dish body 1 is made of polyethylene and has good durability. It has aging resistance and can be used multiple times. A tube body 3 is provided above the lid 2. A tube cover is detachably provided above the tube body 3. A silica gel block 4 is provided inside the tube body 3. There is a silica gel block 4 on the silica gel block 4. Through hole 5, the user opens the tube cover and then inserts the needle for injecting nutrient solution into through hole 5 to add culture fluid to the microorganisms cultivated in dish body 1. This structure is designed to avoid excessive air from the outside. Entering the Petri dish, a tilting ring 6 is provided under the side plate of the dish cover 2 in the dish body 1, which facilitates the user to remove the dish cover 2 from the dish body 1. An inner ring 7 is provided at the bottom of the dish cover 2. The inner ring 7 and the dish cover 2 are arranged in an integrated structure.
