Technical Field

[0001] The utility model relates to the field of supporting equipment for analytical instruments, in particular to a colorimetric dish dry control placement device. Background Art

[0002] The cuvette is generally a cuboid, with the bottom and two sides made of frosted glass, and the other two sides made of optical glass. It is made of fused glass (or quartz) powder, sintered at high temperature and glued. When taking the cuvette, you can only touch the frosted glass on both sides with your fingers to avoid touching the optical surface. Therefore, in order to better place the cuvette, the cuvette rack came into being.

[0003] The cuvette rack is mainly used to conveniently place and protect the cuvette for spectral analysis to improve the efficiency and accuracy of spectral analysis. When the sample volume is large, the amount of cuvettes used is large, and the number of racks required to place the cuvettes also increases, occupying more space. However, the existing multiple cuvettes cannot be flexibly assembled, resulting in the inability to fully utilize the corner space on the laboratory table, ultimately leading to a waste of space.

[0004] Therefore, it is of practical value to study a cuvette that can be flexibly assembled. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] In order to solve the above problems, Figures 1 to 3 As shown, the present scheme provides a cuvette control and placement device, including a base 1, a placement rack 2 and a connecting card block 3; the placement rack 2 is arranged above the base 1, and the placement rack 2 is fixedly connected to the base 1; the placement rack 2 is provided with a plurality of cuvette placement through holes 20 and a connecting card hole 21; the cuvette placement through holes 20 are used to place the cuvette; the connecting card hole 21 is arranged on the peripheral side of the placement rack 2; the connecting card block 3 is arranged between adjacent cuvette control and placement devices, and the connecting card block 3 is engaged with two adjacent connecting card holes 21. When applying, when the sample volume is large, multiple cuvette control and placement devices can be assembled into a shape that adapts to the corner space, making full use of the corner space on the experimental table and reducing the waste of space. For example, when the space on the experimental desktop is strip-shaped, multiple cuvette control and placement devices can be assembled into strips to reduce the waste of space and increase experimental efficiency.

[0025] It should be pointed out that the cuvette dry control placement device is generated by 3D modeling and printing. The printing material is made of degradable PLA plastic filament. The colors of the printing consumables include red, blue, green, and fully transparent. The printing technology can be done using equipment using existing 3D printing technology. Of course, the device material can also be made of other highly wear-resistant flexible resin materials. The advantage is that it provides a rebound and comfortable touch, which can protect the cuvette and reduce the wear of the cuvette.

[0026] Regarding the above-mentioned cuvette placement through hole 20, as Figures 1 to 3 As shown, a plurality of cuvette placement through holes 20 are regularly arranged on the placement rack 2. After adopting this arrangement, the cuvette placement through holes 20 can place a plurality of cuvettes.

[0027] Exemplarily, the plurality of cuvette placement through holes 20 are arranged in an array, or the plurality of cuvette placement through holes 20 are arranged circumferentially.

[0028] To better dry the cuvette, Figures 1 to 3 As shown, the axial direction of the cuvette placement through hole 20 is arranged obliquely relative to the bottom surface of the base 1. After adopting this arrangement, the cuvette can be dried faster.

[0029] Exemplarily, the axis of the cuvette placement through hole 20 forms an oblique angle of 60 to 80 degrees with the horizontal plane, so that the water can be quickly drained after the cuvette is inverted.

[0030] Specifically, the cuvette placement through hole 20 is provided with two inclined inner walls 200, and the two inclined inner walls 200 are arranged in parallel. After adopting this arrangement, the cuvette will be arranged inclined after being placed in the cuvette placement through hole 20, which is more conducive to the drying of the cuvette.

[0031] Regarding the above-mentioned connection block 3 and connection hole 21, Figures 1 to 3 As shown, the connection block 3 matches the connection hole 21 in shape. After adopting this arrangement, the connection block 3 with matching shapes can assemble two adjacent cuvette control and placement devices more tightly together.

[0032] For the connection card hole 21, Figures 1 to 3 As shown, the connecting card hole 21 includes a first hole position 210 and a second hole position 211 which are interconnected; the first hole position 210 opens toward the top of the placement rack 2; the second hole position 211 opens toward the top of the placement rack 2 and toward the adjacent side wall of the placement rack 2.

[0033] In order to achieve better assembly, such as Figures 1 to 3 As shown, the diameter of the first hole 210 is greater than the diameter of the second hole 211. After adopting this setting method, the connecting block 3 and the connecting hole 21 form an assembly like a mortise and tenon structure that matches the shape of the hole.

[0034] For the connection card block 3, if Figures 1 to 3 As shown, the connecting block 3 includes a connecting arm body 30 and a block body 31; both ends of the connecting arm body 30 are connected to the block bodies 31, the diameter of the block bodies 31 is larger than the diameter of the connecting arm body 30, and the connecting arm body 30 is fixedly connected to the two blocks 31; the connecting arm body 30 matches the shape of the second hole position 211, and the block body 31 matches the shape of the first hole position 210. After adopting this setting method, the mortise and tenon connection method of the connecting block 3 and the connecting hole 21 can make the two assembled more tightly.

[0035] In order to collect the water when the cuvette is dried, Figures 1 to 3As shown, a drying water tank 10 is provided on the base 1. After adopting this arrangement, the drying water tank 10 can fully collect the water flowing out of the cuvette during drying, and prevent the water from overflowing onto the experimental table.

[0036] Furthermore, in order to distinguish different cuvettes, e.g. Figures 1 to 3 As shown, the cuvette drying control placement device also includes a partition 4; the partition 4 is arranged between the placement rack 2 and the drying tank 10, and the partition 4 is fixedly connected to the placement rack 2 and the drying tank 10. The partition 4 separates the drying tank 10 to form two independent tank bodies. After adopting this setting method, the two tank bodies correspond to two different placement spaces, and different cuvettes can be placed in different spaces, which is convenient for users to use.

[0037] For example, the two separated spaces may be enclosed by different materials, for example, a glass cuvette is used on one side and a quartz cuvette is used on the other side, and color partitions are provided to prevent the two cuvettes from being mixed up when placed.

[0038] Furthermore, in order to detect whether the cuvette is rinsed clean, e.g. Figures 1 to 3 As shown in the figure, multiple layers of filter paper can be placed at the bottom of the water tank to absorb the residual water in the cuvette. After the upper filter paper is soaked, it can be easily removed and replaced with a new dry filter paper to continue to absorb water and improve the drying efficiency.

[0039] In order to achieve the protection of contrast cuvettes, such as Figures 1 to 3 As shown, the device further comprises a baffle 5, which is installed on the placement rack 2 in a pluggable manner. After adopting this arrangement, the baffle 5 can effectively protect the cuvette.

[0040] To summarize this solution: 1. This solution adopts a detachable connecting card block 3 and a connecting card hole 21, which can make multiple cuvette drying control placement devices flexibly assembled and make full use of space; 2. The cuvettes made of glass and quartz can be distinguished and dried, which protects the cuvettes while being lightweight and durable; 3. The entire device has a reasonable layout, and the bottom layer of filter paper can be replaced when it is wet, so that efficient drying of the cleaned cuvettes can be achieved, minimizing contact with the external laboratory table and reducing pollution.

[0041] From the above, we can know the basic structure and principle of this device. The following will be explained in combination with specific usage scenarios, including the following steps:

[0042] (1) Cleaning of the cuvette. After using the cuvette, if the test solution is acid, if there is any residue, clean it with a weak alkaline solution; if the test solution is alkaline, clean it with a weak acid solution; if the test solution is an organic substance, clean it with a corresponding organic solvent, such as alcohol. After cleaning, rinse the cuvette with pure water. Note that the cuvette cannot be washed with alkaline solution, nor can it be scrubbed with hard cloth or brushes.

[0043] (2) Place the washed cuvette upside down in the corresponding position of the water control device, and place a piece of filter paper cut to the appropriate size on the bottom.

[0044] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
