Description

Technical Field

[0001] This utility model relates to the field of disinfection and cleaning technology, and in particular to a disinfection device for culture dishes used in molecular biology experiments. Background Technology

[0002] A molecular biology laboratory is a facility for the basic analysis and manipulation of biological macromolecules such as nucleic acids and proteins using molecular biology and genetic engineering techniques. This includes nucleic acid extraction and detection, gene fragment cloning and identification, and in vitro protein expression and purification. The laboratory encompasses techniques such as PCR, DNA recombination, agarose gel electrophoresis, preparation and transformation of competent E. coli cells, induction of fusion protein expression in prokaryotes, SDS-PAGE electrophoresis, Coomassie brilliant blue staining, Western blotting, and nickel column affinity chromatography.

[0003] Because highly sensitive experiments such as gene cloning, PCR amplification, and DNA sequencing are frequently performed in molecular biology laboratories, these experiments require a high degree of cleanliness in the experimental environment. Contamination in the experimental environment, such as bacteria, viruses, or DNA fragments, can lead to biased results or even experimental failure. Regular and thorough cleaning and disinfection are crucial aspects of molecular biology laboratory management. Petri dishes, as laboratory vessels used for microbial or cell culture, are frequently used in molecular biology experiments, making effective sterilization and disinfection particularly important. Currently, sterilization and disinfection of petri dishes typically involves either placing the bottom and lid separately into the sterilization equipment or placing them with the bottom and lid closed together. While separating the bottom and lid ensures thorough sterilization, secondary contamination can easily occur during handling and storage after sterilization, affecting experimental results. While placing the bottom and lid together avoids secondary contamination, the internal spaces of the bottom and lid are difficult to sterilize effectively, still affecting experimental results. Therefore, this application provides a petri dish sterilization device for molecular biology experiments to meet these needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a sterilization device for culture dishes used in molecular biology experiments to solve the problems of poor sterilization effect or easy secondary contamination of existing culture dishes used in molecular biology experiments.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A sterilization device for culture dishes used in molecular biology experiments includes a sterilization device with high-temperature sterilization function. The sterilization device is provided with several sets of brackets for separating the bottom and lid of the culture dish. The sterilization device is also provided with an integration frame for integrating the several sets of brackets. The bracket includes horizontally distributed support arms for supporting the bottom of the dish and support plates provided on the support arms for supporting one end of the dish lid to detach from the bottom of the dish.

[0007] Optionally, one end of the support arm is connected to a front baffle, and a rear baffle is fixed to the top of the support arm, which is symmetrically distributed with the front baffle. The support is fixed to the top of the rear baffle.

[0008] Optionally, a pair of support arms are arranged side by side, and one end of the pair of support arms is vertically fixed with a sleeve.

[0009] Optionally, the integrated frame includes a column and a base plate horizontally fixed to the bottom of the column, and the column is sleeved with the sleeve.

[0010] Optionally, a through groove is provided at the top of the column, and a handle is rotatably installed in the through groove.

[0011] Optionally, an anti-slip plate is provided on the top of the front baffle away from the support arm, and the anti-slip plate is inclined from bottom to top towards the side away from the front baffle.

[0012] Optionally, the support arm consists of a hollow arm and a movable arm along the same length direction. A connecting rod is fixedly connected to one end of the movable arm facing the hollow arm and is movably inserted into the hollow arm. A stop block is fixed to one end of the connecting rod extending into the hollow arm. A spring is provided between the stop block and the inner wall of the hollow arm facing the movable arm. The hollow arm is fixedly connected to the sleeve. The rear stop plate is fixed on the hollow arm. The front stop plate is fixed to the end of the movable arm away from the hollow arm.

[0013] Optionally, the support piece is configured with a "7" shaped structure, with one bent end of the support piece facing the front baffle side, and the end of the bent end of the support piece is curved upward in an arc shape.

[0014] Optionally, the front baffle and the rear baffle are curved in an arc shape toward opposite sides.

[0015] Optionally, both the hollow arm and the movable arm are configured as flat structures.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above solution, after the dish bottom and lid are cleaned, the dish bottom is placed on the support arm. The spring force pushes the movable arm towards the hollow arm, allowing the dish bottom to be held in place by the front and rear baffles. The lid is placed above the dish bottom, with one side of the lid resting against the top of the front baffle and against the anti-detachment baffle, while the other side rests on the support plate. This maintains a certain gap between the lid and the dish bottom, ensuring that both the dish bottom and lid are subjected to high-temperature sterilization during the high-temperature sterilization process in the sterilization equipment. The design ensures effective sterilization of the bottom and lid of the petri dish. Furthermore, after sterilization, by holding the bottom of the dish and lifting it towards the front baffle, then pulling it away from the rear baffle, the bottom and lid close instantly upon removal from the holder, allowing for easy and quick retrieval of the petri dish. This eliminates the need to separately lift the bottom, preventing secondary contamination of the bottom and lid. Therefore, this design achieves effective sterilization of both the bottom and lid while facilitating retrieval and storage, avoiding secondary contamination and providing favorable conditions for molecular biology experiments, thus possessing high practical value.

[0018] By integrating the racks and using the sleeves to connect with the columns, multiple racks containing dish bottoms and lids can be integrated onto the columns and placed into the sterilization equipment for high-temperature sterilization. This facilitates batch sterilization of multiple dish bottoms and lids, improving work efficiency. Attached Figure Description

[0034] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, an embodiment of this utility model provides a sterilization device for culture dishes used in molecular biology experiments, including a sterilization device 1 with high-temperature sterilization function. The sterilization device 1 is a commonly used sterilization device in laboratories (including high-temperature sterilization cabinets and autoclaves). The sterilization device 1 contains several sets of brackets 2 for supporting and separating the bottom 19 and lid 20 of the culture dish. The sterilization device 1 also contains an integration frame 3 for integrating the several sets of brackets 2. Each bracket 2 includes horizontally distributed arms 8 for supporting the bottom 19 and a support plate 9 on the arms 8 for supporting one end of the lid 20 detached from the bottom 19. The height of the support plate 9 is greater than the height of the bottom 19. The culture dish composed of the bottom 19 and lid 20 is a common commercially available size. With this structure, the bottom 19 is placed horizontally on the arms 8, and the lid 20 is placed on the bottom 19. One end of the lid 20 is supported by the support plate 9 (e.g., ...). Figure 5As shown in the figure, during the high-temperature sterilization process in the sterilization equipment 1, it can be ensured that both the bottom 19 and the lid 20 are sterilized at high temperature, ensuring the sterilization effect of the bottom 19 and the lid 20. In addition, after sterilization, by holding the bottom 19 and pulling the bottom 19 and the lid 20 away from the tray 9, the bottom 19 and the lid 20 close instantly when pulled away from the tray 2, which can complete the picking up of the culture dish. The picking operation is convenient and quick, without the need to separately lift the bottom 19, avoiding secondary contamination of the bottom 19 and the lid 20. Thus, the structure not only achieves effective sterilization of the bottom 19 and the lid 20, but also facilitates picking up and storage, avoiding secondary contamination, providing favorable conditions for molecular biology experiments, and has high practical value. The sterilization equipment 1 includes, but is not limited to, the autoclave and drying oven commonly used in existing molecular biology experiments. The technical solution is illustrated in the figure of this application using the drying oven as an example.

[0035] The sterilization temperature is 121-132℃ (autoclave) or 160-180℃ (dry sterilization).

[0036] like Figures 3 to 5 As shown, one end of the support arm 8 is connected to a front baffle 10, and a rear baffle 11 symmetrically distributed with the front baffle 10 is fixed to the top of the support arm 8. A support piece 9 is fixed to the top of the rear baffle 11. The front baffle 10 and the rear baffle 11 are used to clamp and limit the bottom of the dish 19. The support arm 8 consists of a hollow arm 14 and a movable arm 15 along the same length direction. A connecting rod 16 that is movably inserted into the hollow arm 14 is fixedly connected to one end of the movable arm 15 facing the hollow arm 14. A stop block 17 is fixed to one end of the connecting rod 16 that extends into the hollow arm 14. A spring 18 is provided between the stop block 17 and the inner wall of the hollow arm 14 facing the movable arm 15. The hollow arm 14 is fixedly connected to the sleeve 13. The rear baffle 11 is fixed on the hollow arm 14, and the front baffle 10 is fixed on the end of the movable arm 15 away from the hollow arm 14. After the dish bottom 19 is placed on the support arm 8, the elastic force of the spring 18 forces the movable arm 15 to tighten towards the hollow arm 14. Thus, the dish bottom 19 is clamped on the support arm 8 by the front baffle 10 and the rear baffle 11, which can prevent the dish bottom 19 from falling.

[0037] like Figures 3 to 5As shown, a pair of support arms 8 are arranged side by side. Both the hollow arm 14 and the movable arm 15 are flat structures, which can stably support the bottom of the dish 19. The front baffle 10 and the rear baffle 11 are curved in an arc shape towards the opposite side. With the elastic clamping of the bottom of the dish 19 by the front baffle 10 and the rear baffle 11, the bottom of the dish 19 can be effectively prevented from falling off and being damaged. The support piece 9 is set in a "7" shape. The bent end of the support piece 9 is set towards the side of the front baffle 10, and the end of the bent end of the support piece 9 is curved upward in an arc shape. After the support piece 9 supports the side of the dish lid 20 away from the bottom of the dish 19, the end of the bent end of the support piece 9 is curved upward in an arc shape, which can prevent the dish lid 20 from slipping off. In addition, an anti-detachment baffle 12 is provided on the top of the side of the front baffle 10 away from the support arm 8, which is used to further prevent the dish lid 20 from slipping off the bottom of the dish 19. The anti-detachment baffle 12 is tilted from bottom to top towards the side away from the front baffle 10 on the side facing the support arm 8, in order to adapt to the tilted outer wall of the lid 20.

[0038] like Figures 2 to 3 As shown, the integrated frame 3 includes a column 4 and a base plate 5 horizontally fixed to the bottom of the column 4. The column 4 is sleeved with the sleeve 13. One end of a pair of support arms 8 is vertically fixed with the sleeve 13. After placing multiple sets of dish bottoms 19 and dish lids 20 on multiple sets of brackets 2, the multiple sets of brackets 2 containing dish bottoms 19 and dish lids 20 can be integrated and fitted onto the column 4 by using the sleeve 13 and the column 4. The whole assembly can then be placed into the sterilization equipment 1 for high-temperature sterilization, which facilitates batch sterilization of multiple sets of dish bottoms 19 and dish lids 20 and improves work efficiency. A through groove 6 is opened at the top of the column 4, and a handle 7 is rotatably installed in the through groove 6. When the handle 7 is rotated to the vertical position, it is easy to fit the sleeve 13 onto the column 4. When the handle 7 is rotated to the horizontal position, the column 4 can be lifted by hand.

[0039] The working principle of the technical solution provided by this utility model is as follows:

[0040] In use, after cleaning the dish bottom 19 and dish lid 20, place the dish bottom 19 on the support arm 8. Using the elastic force of the spring 18, the movable arm 15 is forced to tighten towards the hollow arm 14, thus clamping the dish bottom 19 onto the support arm 8 using the front baffle 10 and the rear baffle 11. Then, place the dish lid 20 on top of the dish bottom 19, with one side of the lid 20 abutting against the top of the front baffle 10 and against the anti-detachment baffle 12, and the other side of the lid 20 resting on... On the tray 9, multiple sets of dish bottoms 19 and dish lids 20 are placed on multiple sets of brackets 2. Then, using the sleeve 13 and the column 4, the multiple sets of brackets 2 containing dish bottoms 19 and dish lids 20 are integrated and fitted onto the column 4, and then placed into the sterilization equipment 1 for high-temperature sterilization. Since the dish bottoms 19 are placed horizontally on the support arm 8, one side of the dish lid 20 is lifted by the tray 9, thus allowing the dish lid 20 to be aligned with the dish bottom. A certain gap is maintained between the plates 19 and 20, for example, the gap between the plate bottom 19 and the plate lid 20 is 5-10mm, to ensure the penetration of high-temperature airflow. This ensures that both the plate bottom 19 and the plate lid 20 are sterilized by high temperature, thus ensuring the sterilization effect on the plate bottom 19 and the plate lid 20. After sterilization, multiple sets of brackets 2 and multiple sets of plate bottoms 19 and plate lids 20 are taken out of the sterilization equipment 1 together using the integrated rack 3. Holding the plate bottom 19, lift the end of the plate bottom 19 facing the front baffle 10 and then pull it away from the side away from the rear baffle 11. The plate bottom 19 and the plate lid 20 close instantly when they are pulled out of the bracket 2. The picking operation is convenient and quick, and easy to operate. There is no need to lift the plate bottom 19 separately, avoiding secondary contamination of the plate bottom 19 and the plate lid 20. It not only achieves effective sterilization of the plate bottom 19 and the plate lid 20, but also facilitates picking and storage, avoids secondary contamination, provides favorable conditions for molecular biology experiments, and has high practical value.
