[0019] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0020] Example 1
[0021] like Figures 1 to 3 As shown, this embodiment proposes a disposable sterile culture dish, including a culture dish body 1, a fixing ring 2 fixed on the upper surface of the culture dish body 1, an isolation plate 3 fixed inside the culture dish body 1, and multiple sets of isolation plates 3 are provided. The surface of the culture dish body 1 is provided with anti-slip particles, and the inner wall surface of the culture dish body 1 is provided with 1mm grid lines. The lengths of the multiple sets of isolation plates 3 in the culture dish are all different.
[0022] In this embodiment, the sample can be placed in conjunction with the petri dish body 1. At the same time, the anti-slip particles can prevent the equipment from slipping and causing the sample to be lost due to the researcher's slip, thereby improving the efficiency of the equipment. The grid lines can quickly and accurately obtain sample information and reduce statistical errors. The isolation plate 3 can divide the inside of the equipment into multiple independent small areas, improving the cultivation efficiency and reducing the number of petri dishes used.

The inner wall surface of the petri dish fixing ring 2 is in contact with the surface of the dish cover 5. The material of the petri dish fixing ring 2 is rubber.
[0025] In this embodiment, the use of the fixing ring 4 increases the friction between the device and the table, preventing the device from shaking during use and causing sample mixing, and also preventing experimental failure. The use of the dish lid 5 can prevent dust and cover the sample inside the culture dish body 1, and also prevent experimental failure, thus improving the efficiency of the device to a certain extent.
[0026] Working principle: in the device use, first, the device is placed in the appropriate location, then through the cooperation of the isolation plate 3, the sample can be placed in the area isolated by the multiple isolation plate 3, then the sample can be observed through the grid line, then the dish cover 5 is placed at the upper end of the petri dish body 1, so that the surface of the dish cover 5 is matched with the inner wall surface of the fixing ring 2, so as to fix the position of the petri dish body 1 and the dish cover 5, then through the cooperation of the fixing ring 4, the displacement or falling of the equipment can be avoided, the above is the whole working principle of the utility model.
