[0002] In the field of biological and agricultural research, seed activation usually requires placing seeds on a solid culture medium slope with a certain slope to promote their germination and growth. Traditionally, this slope is formed by manually pouring liquid culture medium into a test tube and manually adjusting the tilt angle of the test tube before solidification. There are multiple problems with this method: first, manually adjusting the tilt angle of the test tube can easily lead to inconsistent slopes, affecting the comparability and repeatability of the experiment; second, the operation process is technically demanding and cumbersome, and requires high skills and experience of the experimenter; finally, the handmade slope test tube has poor stability when placed, and it is easy to affect the solidification process of the culture medium due to the tipping or movement of the test tube, further affecting the quality and use of the slope; therefore, there is an urgent need for a device that can standardize the production of solid culture medium slopes to improve the consistency and reliability of seed activation.

[0026] A multifunctional test tube rack for making solid medium slopes, such as Figures 1 - 3 shown, includes an outer fixed bracket 1 and an inner test tube rack 2 rotatably mounted within the outer fixed bracket 1. Among them, the outer fixed bracket 1 provides stable support for the entire test tube rack, with a strong structure that can effectively resist vibrations and displacements that may occur during experimental operations. The inner test tube rack 2 is rotatably connected to the outer fixed bracket 1 and can be rotated to a specified angle driven by a motor 8. The design of the test tube rack allows the test tubes 10 to be fixed at different angles to meet the experimental requirements at different stages. The inner test tube rack 2 is made of corrosion-resistant materials to adapt to various laboratory environments; a rotary drive device is provided on the outer fixed bracket 1 and is connected to the inner test tube rack 2 and used to drive the inner test tube rack 2 to swing. The test tubes 10 are adaptively positioned on the inner test tube rack 2, and under the drive of the rotary drive device to swing the inner test tube rack 2, the test tubes 10 are adjusted to the required inclination angle. A liquid collecting device for collecting the liquid leaking from the test tubes 10 is provided at the lower end of the inner test tube rack 2; the above structure solves the problems of poor consistency and inconvenient operation in the production of solid medium slopes during the traditional seed activation process, improves the efficiency and accuracy of seed activation and solid medium treatment in the laboratory, reduces human errors and labor intensity during the operation process, has good operation flexibility, effectively manages the possible liquid spills in the experiment, keeps the working environment clean and tidy, and is an ideal choice for standardized laboratory operations.

[0027] To avoid the malfunction or maintenance of the rotary drive device from affecting the normal tilting operation of the inner test tube rack 2, a manual adjustment device is specifically provided on the outer fixed bracket 1, which is connected to the inner test tube rack 2 and used to manually control the swinging angle of the inner test tube rack 2; specifically, the specific structure of the manual adjustment device is as follows: the manual adjustment device includes a handwheel bolt 6, and a chute 7 concentric with the hinge point of the outer fixed bracket 1 and the inner test tube rack 2 is formed on the side wall of the outer fixed bracket 1. The handwheel bolt 6 passes through the chute 7 and is threadedly connected to the inner test tube rack 2. When the handwheel bolt 6 is loosened, the inner test tube rack 2 is swung along the chute 7 to the required tilting angle position of the test tube 10, and then the handwheel bolt 6 is tightened. When manually rotating the test tube rack, the handwheel bolt 6 can be slid in the chute 7 to the corresponding scale and then tightened to fix it; when using the motor 8 for automatic control, it is also possible to observe whether the drive of the motor 8 is accurate and calibrated through the angle scale around the chute 7; specifically, the chute 7 is a semi-circular ring groove, and angle graduation lines are provided at the edge of the chute 7; in the above structure, the combination of the detachable design of the motor 8 and the manual adjustment device further increases the flexibility of the equipment, enabling the test tube rack to be used in different environments. For example, after detaching the motor 8, it can be placed in an oven for high-temperature treatment or subjected to deep cleaning without damaging the motor components, with a wide range of applications;

[0028] The specific structure of the rotary drive device is as follows: the rotary drive device uses a motor 8, which is installed on the outer side wall of the outer fixed bracket 1, and the output shaft of the motor 8 is connected to the inner test tube rack 2 and used to drive the inner test tube rack 2 to swing; among them, the motor 8 is connected to the motor controller 9, and the motor controller 9 controls the motor 8 to rotate to a set angle; by introducing the motor 8, the angle adjustment of the test tube rack is more accurate, and the user can easily set and adjust the angle of the test tube 10 through the motor controller 9, thereby reducing the human error and labor intensity during the operation process; the motor 8 is designed to be easily detachable, and this function is particularly suitable for situations where the test tube rack needs to be placed in an environment that is not conducive to the operation of the motor 8 during experimental operations, such as cases where high-temperature treatment or deep cleaning is required; after detaching the motor 8, the inner test tube rack 2 will remain at the last rotation angle before detachment and be fixed by the manual adjustment device to avoid affecting the test results due to position changes.

[0029] The specific structure of the rotational connection between the inner test tube rack 2 and the outer fixed bracket 1 is as follows: connection shafts are fixedly installed on the outer side walls of both sides of the inner test tube rack 2 and are rotationally connected to the corresponding side walls of the outer fixed bracket 1, and the output shaft of the motor 8 is fixedly connected to the connection shaft on the same side; in the above structure, the structure of rotatably installing the inner test tube rack 2 inside the outer fixed bracket 1 enables the user to accurately adjust the tilting angle of the test tube 10 by adjusting the inner test tube rack 2 according to experimental requirements, which is crucial for making a culture medium inclined plane with a certain slope and ensures the repeatability and reliability of the experiment;

[0030] The specific structure of the liquid collecting device is as follows: The liquid collecting device is a drawer 5 with a handle on the front wall, and the drawer 5 is inserted at the lower end of the inner test tube rack 2; In the above structure, by arranging the drawer 5 below the test tube support plate 4 with the liquid leakage function on the inner test tube rack 2, the liquid overflow that may occur in the experiment is effectively managed, and the working environment is kept clean and tidy;

[0031] Among them, the outer fixed bracket 1 and the inner test tube rack 2 have the same shape; Specifically, the inner test tube rack 2 adopts a structure of two side plates and a U-shaped frame that fixedly connects the lower ends of the two side plates. Above the bottom plate of the inner test tube rack 2, there is a test tube support plate 4 fixedly connected to the inner side walls of the two side plates, and there are no less than two test tube placement hole plates 3 distributed up and down above the test tube support plate 4. The test tube placement hole plate 3 has multiple holes for placing the test tubes 10, and each hole is precisely designed to ensure that the test tubes 10 are vertically placed or tilted at a set angle. The test tubes 10 are inserted into the test tube holes on the test tube placement hole plate 3, and the lower ends of the test tubes 10 are positioned on the test tube support plate 4; Specifically, the liquid collecting device is inserted between the bottom plate of the inner test tube rack 2 and the test tube support plate 4, and several liquid leakage holes for liquid to leak into the liquid collecting device are made on the test tube support plate 4; Among them, the inner test tube rack 2, the test tube placement hole plate 3 and the test tube support plate 4 are all made of corrosion-resistant materials. The test tube support plate 4 has the function of liquid leakage, so that the overflowing liquid can be discharged when processing liquid samples, and the liquid overflowing from the test tubes 10 is prevented from accumulating on the test tube support plate 4.

[0032] First, the experimenter prepares the work of smearing the solid medium. Before smearing the solid medium, it is necessary to adjust the test tube rack to ensure that the inclination of the test tubes is suitable for smearing; The operator inputs the angle command required to rotate on the motor controller 9, and the motor 8 is immediately started and precisely rotates the inner test tube rack 2 until the test tubes 10 are tilted to the set angle. This angle allows the medium to form a uniform inclined plane in the test tubes 10, which is beneficial to the uniform contact and adsorption of the seeds.

[0033] After the inclined plane smearing is completed, the operator needs to let the medium solidify in the test tubes. For this purpose, the operator uses the motor controller again and inputs another required rotation angle command to rotate the test tube rack to the position where the test tubes 10 are completely vertical. This helps the medium to solidify uniformly in the test tubes 10 and prevents uneven distribution caused by inclination.

[0034] After the culture medium has solidified, if it is necessary to place the test tube rack and the test tubes 10 in an oven for high-temperature treatment, such as sterilization or drying, the operator can simply disassemble the motor 8 that controls the rotation of the test tube rack. Since the design of the motor 8 takes into account the unsuitability of the high-temperature environment, the disassembly function allows the operator to safely place the test tube rack and the test tubes 10 together in the oven. Since the inner test tube rack 2 can remain fixed at the current rotation angle after the motor 10 is disassembled, this ensures the stability of the position of the test tubes 10 during the treatment process.

[0035] After the drying treatment is completed and the test tube rack is taken out of the oven, it is usually necessary to clean the test tubes to remove the residual culture medium or other substances. After cleaning, in order to effectively dry the water inside the test tubes, the operator sets the test tube rack to rotate to 90 degrees through the motor controller 9 to invert the test tubes 10 so that the water can flow out. The design of the bottom of the test tubes 10 allows the water to flow into the lower drawer 5.

[0036] After the drying is completed, the operator simply takes out the drawer 5 located under the test tube support plate 4. Since the drawer 5 collects all the waste water, the operator can easily pour it out and handle the waste water, which not only maintains the cleanliness of the experimental bench but also meets the requirements of laboratory internal management and environmental protection.

[0037] Through the above operation process, the multi-functional test tube rack of this structure demonstrates its efficiency and practicality in daily laboratory operations. From smearing solid culture medium to high-temperature treatment, and then to drying after cleaning, each step is carefully designed to ensure the convenience of operation and the accuracy of the experiment. In addition, the structural design of the test tube rack takes into account the flexibility of operation and the adaptability to the environment, making it an indispensable device in modern biological laboratories.

[0038] This technical solution comprehensively improves the convenience, safety and efficiency of experimental operations and is an ideal choice for standardized laboratory operations.
