Description

Technical Field

[0001] This utility model relates to the field of microbial culture dish technology, specifically to a microbial culture dish. Background Technology

[0002] A petri dish is a laboratory vessel used for culturing microorganisms or cells. It consists of a flat, disc-shaped base and a lid, and is generally made of glass or plastic. Petri dishes are basically divided into two categories: plastic and glass. Glass petri dishes can be used for the culture of plant materials, microorganisms, and adherent cultures of animal cells. Plastic petri dishes are likely made of polyethylene and are available in disposable and reusable versions. They are suitable for laboratory inoculation, streaking, and bacterial isolation procedures, and can be used for the culture of plant materials.

[0003] Traditional petri dishes are round, transparent glass or other materials. They need to be placed one by one on a storage rack, which is not conducive to saving space. In addition, traditional petri dishes are not very airtight, and are easily contaminated by air when culturing anaerobic microorganisms, which can lead to inaccurate observation results. Utility Model Content

[0004] The purpose of this invention is to provide a microbial culture dish that solves the problems of traditional culture dishes, which require them to be placed one by one on a storage rack, making them inefficient in terms of space saving. In addition, traditional culture dishes are not very well sealed, making them susceptible to air contamination when culturing anaerobic microorganisms, which can lead to inaccurate observation results.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A microbial culture dish includes a culture dish with a base cap snapped to its top. Lower magnetic pillars are embedded in each of the four corners of the culture dish, with the bottoms of the lower magnetic pillars extending outside the culture dish. Upper magnetic pillars are embedded in the bottom of each of the four corners of the base cap at positions corresponding to the lower magnetic pillars. Slots are formed in the top of each of the four corners of the base cap at positions corresponding to the lower magnetic pillars. A sealing ring is fitted onto the top of the culture dish at a position corresponding to the bottom of the base cap.

[0007] Preferably, both the culture dish and the base cover are square in design, and interlocking grooves are provided on opposite sides.

[0008] Preferably, both the petri dish and the base cap are made of ultra-white glass.

[0009] Preferably, the upper and lower magnetic pillars have opposite magnetic properties on opposite sides.

[0010] Preferably, the bottom end of the lower magnetic post is connected to the slot by a snap-fit ​​connection.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, both the culture dish and the base cover are designed in a square shape, with lower and upper magnetic pillars embedded at the four corners respectively. This allows for magnetic attraction after the culture dish and the base cover are snapped together, ensuring a secure connection. The snap-on magnetic design also makes it easy to open the base cover. Furthermore, the design incorporates a detachable sealing ring, which can be freely installed or removed depending on whether the microorganisms are aerobic or anaerobic. This improves the flexibility of the culture dish and prevents air contamination during anaerobic microbial cultivation, ensuring the accuracy of observation results.

[0013] 2. In this utility model, the lower magnetic column extends downward and the four corners of the top of the base cover are provided with corresponding slots, which can be connected to each other to facilitate the vertical stacking of multiple composite culture dishes in sequence, saving space; when stacking, the lower magnetic column at the bottom of the previous composite culture dish will be magnetically attracted to the upper magnetic column at the top of the next composite culture dish, ensuring structural stability and good anti-fall performance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution:

[0021] A microbial culture dish includes a culture dish 1 for microbial culture. A base cap 2 is snap-fitted to the top of the culture dish 1 to seal the top, ensuring the internal and external environments of the culture dish are relatively independent, facilitating microbial culture. Lower magnetic pillars 3 are embedded in each of the four corners of the culture dish 1, with the bottom of the lower magnetic pillars 3 extending beyond the culture dish 1. Upper magnetic pillars 4 are embedded in the bottom of each of the four corners of the base cap 2, corresponding to the lower magnetic pillars 3, for magnetic attraction between the culture dish and the base cap, ensuring structural strength. Slots 5 are provided at the top of each of the four corners of the base cap 2, corresponding to the lower magnetic pillars 3, for engaging the lower magnetic pillars, facilitating the vertical stacking of multiple composite culture dishes and saving space. A sealing ring 6 is fitted onto the top of the culture dish 1, corresponding to the bottom of the base cap 2, for sealing the base cap and the culture dish, improving the overall sealing effect of the culture dish to meet the needs of anaerobic microbial culture. This effectively prevents air pollution during microbial culture and ensures the accuracy of microbial culture observation results.

[0022] In this embodiment, please refer to Figure 2 , Figure 3 Both the petri dish 1 and the base cover 2 are square in design, and there are interlocking grooves on opposite sides to meet the structural design of the petri dish and achieve the function of a microbial culture dish.

[0023] In this embodiment, both the culture dish 1 and the base cover 2 are made of ultra-white glass to ensure the transparency of the composite culture dish and facilitate the observation of microbial culture.

[0024] In this embodiment, the upper magnetic column 4 and the lower magnetic column 3 have opposite magnetic properties on opposite sides. The magnetic principle of attraction between opposite poles is used to ensure the structural strength of the single culture dish and the base cap and the stability of the stacked structure between multiple composite culture dishes, thus ensuring structural strength and preventing them from falling.

[0025] In this embodiment, please refer to Figure 4 The bottom end of the lower magnetic column 3 is connected to the slot 5 by a snap-fit, which meets the structural design requirements.
