Description

Technical Field

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

[0002] In the field of microbiology, petri dishes are the basic tools for microbial culture and research. However, the petri dishes widely used in laboratories at present have limited functions and some limitations. These problems affect the efficiency of experiments and the accuracy of results to some extent.

[0003] First, conventional petri dishes typically lack internal partitions, making it difficult to simultaneously culture multiple microorganisms or conduct control experiments within a single dish. Second, traditional petri dishes lack counting lines, making it difficult for operators to count colonies quickly and accurately, increasing the complexity of experimental procedures and the likelihood of counting errors. Furthermore, existing petri dishes are inconvenient to stack, not only taking up laboratory space but also posing a risk of slipping or tipping over due to improper stacking, resulting in damage. Finally, during inoculation, the opening angle of the petri dish lid cannot be too large, as this may lead to extensive exposure of the culture medium during the procedure, allowing exogenous microorganisms to enter the petri dish and increasing the risk of contamination. Utility Model Content

[0004] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a microbial culture dish that improves the efficiency, accuracy and safety of microbial culture.

[0005] To achieve the above objectives, this utility model provides the following solution: A microbial culture dish includes a dish body and a lid. The dish body has an inner ring region and an outer ring region concentrically surrounding the inner ring region. The inner ring wall of the inner ring region and the outer ring wall of the outer ring region are coaxially disposed on the bottom of the dish body. The lid is fastened to the inner ring wall. A partition plate is disposed within the inner ring region of the dish body. A scale recognition unit is provided on the upper surface of the lid. The center of the lid, the center of the dish body, and the center of the partition plate coincide. The outer ring wall is provided with several sample information marking areas. In routine operations, sample information is usually marked on the plate lid, which can obstruct the view and affect the observation of the culture medium status and the growth of microbial samples. Marking the sample information on the outer ring wall can avoid this problem and can also achieve zoned sample marking of several culture media. At the same time, even when the culture is inverted or stacked, the microbial samples in each culture dish can still be quickly identified, which facilitates sample management.

[0006] In one feasible implementation, a separator divides the inner region into several equal culture zones.

[0007] In one feasible implementation, horizontal scale lines are provided on the outer side of the annular inner wall corresponding to several equal culture zones.

[0008] Setting horizontal graduations helps operators quickly and accurately pour consistent culture medium into several equal culture zones, ensuring uniform culture medium thickness and consistent culture conditions, improving the accuracy of zoned culture, and enhancing the reproducibility and scientific rigor of experiments.

[0009] In one feasible implementation, the height of the partition plate is equal to the height of the annular inner wall.

[0010] In one feasible implementation, the divider is a cross-shaped divider.

[0011] In one feasible implementation, the inner ring wall of the inner ring region is higher than the outer ring wall of the outer ring region.

[0012] By setting inner and outer ring areas, the opening angle during vaccination is controlled below a safe threshold (e.g., 45°), reducing the exposed area. Furthermore, the double physical barrier of the outer and inner ring walls further prevents contamination.

[0013] In one feasible implementation, the distance between the inner annular wall of the inner ring region and the outer annular wall of the outer ring region is 5-10 mm.

[0014] In one feasible implementation, the scale recognition unit is a number of grid lines and / or a number of scale lines and / or a number of scale circles.

[0015] By setting several graduated circles, it is possible to visually observe and measure the size of colonies, conduct antibacterial tests, statistically analyze colony distribution patterns, and quickly locate colony positions.

[0016] In one feasible implementation, the grid lines are square grid lines.

[0017] The grid lines facilitate colony counting and location.

[0018] In one feasible implementation, the scale lines are a circular array of scale lines centered on the center of the lid.

[0019] By setting scale lines, it is possible to visually observe and measure colony size, conduct antibacterial tests, statistically analyze colony distribution patterns, and quickly locate colony positions.

[0020] In one feasible implementation, several graduated circles expand outward from the center of the lid.

[0021] In one feasible implementation, the radius difference between two adjacent scale circles is 1-10 mm.

[0022] In one feasible implementation, multiple microbial culture dishes are stacked one on top of the other by setting up a silicone pad ring.

[0023] In one feasible implementation, the silicone pad ring is a medical-grade silicone pad ring.

[0024] The medical-grade silicone gasket ring can withstand high-temperature and high-pressure steam sterilization, ensuring repeated sterilization and use in a laboratory environment.

[0025] In one feasible implementation, a silicone gasket ring is disposed between the lid and the annular outer wall.

[0026] In one feasible implementation, the top of the silicone pad ring is higher than or flush with the top of the lid.

[0027] In one feasible implementation, the bottom end of the silicone pad ring is placed at the top of the outer wall of the ring.

[0028] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model provides a microbial culture dish with added internal partitioning function to realize the partitioning culture of multiple strains or to conduct control experiments.

[0029] (2) This utility model provides a microbial culture dish, which provides an intuitive reference for colony counting or antibacterial experiments through the scale recognition unit on the lid, thereby improving the accuracy and efficiency of counting or measurement.

[0030] (3) This utility model provides a microbial culture dish, which optimizes the stacking setup, reduces space occupation, and reduces damage to the culture dish caused by improper operation during stacking. Moreover, the medical-grade silicone pad ring can withstand high temperature and high pressure steam sterilization, ensuring that it can be repeatedly sterilized and used in the laboratory environment.

[0031] (4) This utility model provides a microbial culture dish that limits the opening and closing angle of the culture dish lid and reduces the entry of exogenous microorganisms during the inoculation process.

[0032] (5) This utility model provides a microbial culture dish, which marks the sample information on the outer ring wall, allowing for direct observation of the state of the culture medium and the growth of the microbial sample. It can achieve the partitioned sample marking of several culture media, and can quickly identify the microbial sample in each culture dish even when it is inverted or stacked, which is convenient for sample management.

[0037] The inner ring region 1 of the petri dish is equipped with a partition plate 4, such as a cross-shaped partition plate 4, which divides the inner ring region 1 into several equal culture zones. This gives the petri dish an internal partitioning function, facilitating the simultaneous culture of multiple microorganisms or the conduct of control experiments.

These graduation lines 7 help the operator quickly and accurately pour consistent culture medium into the several equal culture zones, ensuring uniform culture medium thickness and consistent culture conditions, improving the accuracy of partitioned culture, and enhancing the reproducibility and scientific rigor of the experiment. The height of the partition plate 4 is equal to the height of the annular inner wall, with the annular inner wall of the inner ring region 1 being higher than the annular outer wall of the outer ring region 2.
