[0031] It should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly.

[0034] This utility model provides a technical solution: a circular rotating sample holder that can hold various types of single crystal culture flasks, see [link to related document]. Figure 1 It includes a base 1, a sample plate and a spacer 4. The upper surface of the base 1 is provided with a rotating shaft 2. The sample plate has a first through hole and is rotatably mounted on the rotating shaft 2 through the first through hole. The sample plate has several insertion holes of different diameters for placing culture bottles of different sizes. The spacer has a second through hole and is mounted on the rotating shaft 2 through the second through hole. The spacer 4 is located between the sample plate and the base 1.

[0035] Specifically, the circular rotating sample holder has a rotating shaft on the base 1, on which the sample tray is rotated and fitted with insertion holes of different diameters, so that culture bottles of various sizes can be placed. At the same time, the spacer 4 is fitted on the rotating shaft 2 and placed between the sample tray and the base 1. This arrangement not only facilitates the flexible rotation of the sample tray to pick up and put in the culture bottles, but also uses the spacer to provide stable support and isolation protection.

[0036] As an optional implementation, in some embodiments, the sample tray has three layers: a placement layer 5, an upper support layer 6, and a lower support layer 3, arranged sequentially from top to bottom. The placement layer 5 has several insertion holes. The diameter of the upper support layer 6 is smaller than the diameter of the lower support layer 3, and the diameter of the placement layer 5 is larger than the diameter of the upper support layer 6 but not larger than the diameter of the lower support layer 3. The placement layer 5, upper support layer 6, and lower support layer 3 are designed as a single unit, and these three layers are distributed according to a specific diameter relationship. The difference in diameter between the upper support layer 6 and the lower support layer 3, and their matching with the dimensions of the placement layer 5, form a stable stepped support, enhancing the overall structural stability. Simultaneously, the insertion holes in the placement layer 5 are used to place culture flasks, and the upper support layer 6 and the lower support layer 3 can respectively provide support and assistance for culture flasks placed in different positions, preventing the culture flasks from shaking or tipping over, and ensuring the safe and stable progress of the single crystal culture process.

[0037] In the above embodiment, the placement layer 5 is further provided with four rings of sockets from the center to the edge. The first ring of sockets is located close to the center of the placement layer 5. The first and second rings each have 8 sockets, and the diameter of each socket is 13mm. The spacing between the first ring of sockets is 0.4cm, the spacing between the second ring of sockets is 0.3cm, the third ring has 16 sockets, and the diameter of each socket is 16mm. The spacing between the third ring of sockets is 0.5cm. The fourth ring of sockets has two diameters, 20mm and 24mm, which are arranged alternately and spaced 1cm apart.

[0038] Specifically, this sample rack can hold four sizes of culture flasks, such as... Figure 2 As shown, culture flask A is 34mm high, 11.6mm in diameter, and has a capacity of 2.5ml; culture flask B is 45mm high, 14mm in diameter, and has a capacity of 4ml; culture flask C is 61mm high, 16mm in diameter, and has a capacity of 8ml; and culture flask D is 50mm high, 22mm in diameter, and has a capacity of 10ml. The corresponding placement layer 5 has four sizes of holes. The outermost ring (fourth ring) has two diameters: 24mm and 20mm, for placing culture flasks C and D, with 8 holes in each ring, intersecting each other with a 1cm interval. The third ring has 16 holes with a diameter of 16mm, for placing culture flask B, with a 0.5cm interval between the holes. The second and first rings have 8 holes each with a diameter of 13mm, for placing culture flask A, with intervals of 0.3cm and 0.4cm respectively.

[0039] As an optional implementation, in some embodiments, the height between the placement layer 5 and the lower support layer 3 is 2.5 cm, and the height between the placement layer 5 and the upper support layer 3 is 2 cm. This differentiated height setting ensures sufficient space between the placement layer 5 and the lower support layer 3 to facilitate air circulation and create a favorable environment for single crystal cultivation. It also ensures a reasonable distance between the placement layer 5 and the upper support layer 6, providing stable support for the placement layer 5 while avoiding an overly compact structure. This facilitates the handling and placement of culture flasks by operators, improving overall ease of use and practicality.

[0040] As an optional implementation, in some embodiments, the base 1 is circular in shape with a diameter of 20cm and a thickness of 0.5cm; the placement layer 5, the upper support layer 6, and the lower support layer 3 are all circular in shape, with the upper support layer 6 having a diameter of 13cm and the lower support layer 3 having a diameter of 20cm; the partition plate 4 is circular in shape with a diameter of 4cm and a thickness of 0.5cm; the rotating shaft 2 is located at the center of the base 1 with a diameter of 1.5cm and a height of 7.5cm; the diameters of the first through hole and the second through hole are both 1.6cm.

[0041] Specifically, the base 1, each layer of the sample tray, and the partition 4 are all circular with corresponding diameters and thicknesses. The rotating shaft 2 is centrally located on the base 1, and the diameters of the first and second through holes are adapted to the rotating shaft 2. This precise dimensional setting ensures that the overall structure is compact, stable, and flexible in rotation, and can stably support culture bottles of different sizes. It also makes reasonable use of space, making it convenient for operators to pick up and put down culture bottles. Furthermore, it ensures the accuracy and coordination of the assembly of each component, which is conducive to the stable progress of the single crystal culture process.

[0042] Instructions for using this sample rack: Dissolve pure solid compounds in culture flasks of different sizes using different solvent systems. Then seal the culture flasks with sealing film or plastic wrap, and poke several holes with a needle. As the solution in the culture flask gradually moves from an unsaturated state to a saturated or even supersaturated state, crystals will precipitate in the culture flask. When observing the crystal growth, it is not necessary to lift the culture flask; observation can be done by rotating the sample tray. This avoids crystal growth failure caused by frequent sample lifting and vibration. Furthermore, multiple crystal samples can be cultured simultaneously, improving the efficiency of successful crystal growth.
