Description

Technical Field

[0001] The utility model relates to the technical field of experimental auxiliary instruments, in particular to a simple culture dish batch sealing device. Background Art

[0002] A petri dish is a laboratory dish used for microbial or cell culture. It consists of a flat disc-shaped bottom and a lid, and is generally made of glass or plastic. It is suitable for laboratory inoculation, streaking, and bacterial isolation operations, and can be used for the cultivation of plant materials. Common petri dish specifications are: 1. 35mm petri dish: diameter 35mm, depth 10mm, volume 8ml. 2. 60mm petri dish: diameter 60mm, depth 15mm, volume 20ml. 3. 100mm petri dish: diameter 100mm, depth 20mm, volume 60ml. 4. 150mm petri dish: diameter 150mm, depth 25mm, volume 100ml. 5. 245mm petri dish: diameter 245mm, depth 30mm, volume 500ml.

[0003] In the actual microbial experiment process, in order to maintain the sterile state to avoid contamination or to provide sealing protection, the inoculated culture dishes need to be sealed. When there are a large number of culture dishes, the efficiency of sealing a single culture dish is low, and multiple culture dishes need to be sealed in batches. In the existing laboratory batch sealing process, there are no auxiliary instruments that can be used, and the operation is completely dependent on manual operation. Because the sealing film itself has a certain amount of weight, it is easy for multiple culture dishes to be unstable during the sealing process, and the sealing efficiency is low.

[0004] Therefore, it is now urgent to design a simple culture dish batch sealing device suitable for laboratory use and capable of improving sealing efficiency. Summary of the invention

[0005] In order to solve the deficiencies in the prior art, the utility model provides a simplified culture dish batch sealing device, which has a simple structure and is easy to operate, and can improve the efficiency of culture dish batch sealing.

[0021] To facilitate those skilled in the art to understand the present invention, specific implementations of the present invention are described below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, the utility model provides a simple culture dish batch sealing device, including a base 1, a sealing film fixing plate 2, a column 4, a rotating shaft 5, a culture dish fixing plate 6, a sealing film pasting column 7, a pressure plate 8, a crossbeam 9, a rotating column 10 and a handle.

[0023] The sealing film fixing plate 2 is fixed on the base 1 and is horizontally arranged at a distance from the culture dish fixing plate 6. To ensure the stability of the sealing, the sealing film fixing plate 2 is at the same height as the culture dish fixing plate 6. The column 4 is perpendicular to the center position of the sealing film fixing plate 2 and is arranged at the center position of the sealing film fixing plate 2. The sealing film roll 3 is fixed on the column 4.

[0024] The bottom surface of the rotating shaft 5 is fixed on the base 1, and the culture dish fixing plate 6 is fixed on the upper end of the rotating shaft 5, and performs synchronous rotation operation with the rotating shaft 5. Of course, it is not limited to the rotating matching structure of the rotating shaft 5 and the bearing in this embodiment, and any rotating shaft 5 that can achieve the above purpose in the prior art can be replaced.

[0025] In order to use different types of culture dishes, the diameter of the culture dish fixing plate 6 is set to 150mm. The sealing film pasting column 7 is arranged on the side of the culture dish fixing plate 6 opposite to the column 4, and is vertically fixed on the base 1. The setting of this position can realize the circumferential sealing of the culture dish during the sealing process, and after sealing, the sealing film head is fixed by the sealing film pasting column 7 after rotating to the position of the sealing film pasting column 7, and then the corresponding sealing film on the culture dish is cut to achieve a batch of sealing. In order to further ensure the pasting efficiency of the sealing film pasting column 7, the outer side wall of the sealing film pasting column 7 is set to be rough, which increases the friction with the sealing film and facilitates the pasting of the sealing film.

[0026] The culture dish fixing mechanism comprises a pressure plate 8, a crossbeam 9, a rotating column 10 and a rotating handle. The rotating handle is arranged at the tail of the rotating column 10 perpendicular to the rotating column 10. The pressure plate 8 is arranged at the top of the rotating column 10 and is rotatably connected with the rotating column 10. In the present embodiment, the rotating column 10 and the pressure plate 8 are rotatably connected via a bearing. Of course, in the actual operation process, it is not limited to this rotating structure, and other structures that can be realized by the prior art can be used. The pressure plate 8 is arranged as a trumpet-shaped structure, and the material of the pressure plate 8 is plastic. In order to further avoid damage to the culture dish by the pressure plate 8, elastic silica gel can be arranged on the bottom surface of the pressure plate 8.

[0027] The rotating column 10 passes through the crossbeam 9, which is horizontally arranged and one end of which is vertically fixedly connected to the sealing film pasting column 7. Specifically, an external thread is arranged on the outer wall of the rotating column 10, and a corresponding internal thread is arranged at the contact position between the crossbeam 9 and the rotating column 10.

[0028] During specific use, the sealing film roll 3 is put on the column 4, and several culture dishes that need to be sealed are vertically arranged on the culture dish fixing plate 6. By rotating the rotating handle, the crossbeam 9 rotates and moves downward, driving the pressure plate 8 to move downward, and the culture dishes are vertically compressed. After the culture dishes are compressed, the experimenter pulls out the sealing film from the sealing film roll 3 to seal the culture dishes. When the sealing film contacts the culture dishes, the culture dish fixing plate 6 is rotated to seal the culture dishes. After the sealing is completed, the sealing film is cut, and the remaining sealing film mouth is pasted on the sealing film pasting column 7, so as to seal the next batch of culture dishes in the same experiment and improve the sealing efficiency. The rotating handle is rotated in the opposite direction to take the culture dishes out of the culture dish fixing plate 6, and then the next batch of culture dishes are packaged.

[0029] The above-described implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model shall be included in the protection scope of the claims of the utility model.
