In order to fix the cuvette in the cuvette, as shown in fig. 6, a fixing block 142 is generally fixed in the cuvette, the fixing block 142 has a slot 1421, and the cuvette can be inserted into the slot 1421. Of course, the fixing of the cuvette may also adopt other structures, and this embodiment is only for illustration.

When the device is used and the concentration of a sample to be detected is required to be detected, the sample to be detected can be firstly added into the cuvette, then the cuvette is fixed in the cuvette, and the wavelength of the ultraviolet visible light source is adjusted to a required value; after the ultraviolet visible light source is powered on, the notch of the mounting groove 14 is covered with the shading cover, so that the absorbance of the sample to be measured can be measured (the absorbance of substances within the wavelength range of 190nm to 760nm can be measured by using the method, the specific measurement process is the prior art and is not described herein any more), and then the concentration value corresponding to the sample to be measured can be obtained by analyzing the measured absorbance. After the test is completed, the cuvette, the light shielding cover, and the like can be stored in the second storage tank 21.

In detail, a standard solution is generally purchased, the standard solution is diluted to obtain diluted solutions with different concentrations, each diluted solution is added into a cuvette, the absorbance corresponding to the diluted solution can be measured by using the above operation, and a relationship curve between the concentration value and the absorbance of the standard solution can be obtained by testing the absorbance of a plurality of groups of diluted solutions. And then, when the concentration of the sample to be detected with unknown concentration is required to be detected, the operation steps can be adopted to operate to obtain the absorbance of the sample to be detected, and then the measured absorbance is compared with the concentration value of the standard solution and the relation curve of the absorbance, so that the concentration value of the sample to be detected can be obtained.

In practical application, in order to facilitate adjustment of the rotation speed of the motor and the wavelength of the uv-vis light source, as shown in fig. 1, the whole test box further includes a first control panel 4 and a second control panel 5 disposed on the side surface of the first storage box 1, the first control panel 4 is electrically connected to the motor, and the second control panel 5 is electrically connected to the uv-vis light source.

Specifically, the first control panel 4 generally has a first display screen having a start button and a stop button, and a rotation speed value of the motor can be input on the first display screen to control the operation of the motor. Thus, when the start button is pressed, the first control panel 4 controls the motor to operate, and drives the permanent magnet steel to rotate. Typically, the second control panel 5 has a second display screen, which also has a start button and a stop button, on which the wavelength of the uv-vis light source can also be input. The specific control process is the prior art and is not described herein again.

Generally, since the equipment in the first storage tank 11 is not taken out during the test, and only needs to be checked or taken out when the equipment is overhauled occasionally, the first cover plate at the opening of the first storage tank 11 is generally detached rarely after being fixed, and is closed all the time during the test. The instruments and the medicines in the second storage tanks 21 need to be taken out for use during the test, so that the second cover plate is detached when the instruments or the medicines need to be taken out from the notches of the second storage tanks 21, and the second cover plate is fixed and closed after the test is finished. The arrangement of the first cover plate and the second cover plate can ensure that the internal equipment, instruments or medicaments cannot overturn in the moving process, and a certain protection effect is achieved.

In addition, in order to facilitate the fastening of the nut 32 on the inner surface of the bottom of the first storage box 1 when the support rod 3 is required to be mounted in the test process, the first cover plate may be shaped to have a special shape, so as to leave the mounting hole 13 and further facilitate the mounting of the nut 32. The shape of the first cover plate is determined according to the requirement, and the invention is not limited to this.

Further, for convenience of processing and installation, as shown in fig. 3, a plurality of partition plates 22 are detachably provided in the second storage box 2, each partition plate 22 partitions the inside of the second storage box 2 into a plurality of second storage tanks 21, and each second cover plate is detachably coupled to the corresponding partition plate 22. When the partition plate 22 is mounted, a support leg receiving space 61 and a fixing bar receiving space are left in the second storage box 2, and how to divide the second storage tanks 21 is planned according to actual needs.

More specifically, generally, opposite ends of each partition plate 22 respectively protrude outward to form a plurality of first protrusions and a plurality of second protrusions, a plurality of first slots are formed in the inner wall of the bottom surface of the second storage box 2, and each first protrusion can be inserted into a corresponding first slot, so that the partition plates 22 and the second storage box 2 are fixed. A plurality of second slots are respectively formed in each second cover plate, and each second protrusion can be inserted into the corresponding second slot, so that the second cover plates and the partition plates 22 are fixed. Thus, each partition plate 22 can be inserted into the corresponding first slot as needed, and the space of the second storage slot 21 can be adjusted by freely adjusting the insertion position thereof as needed. Of course, the partition plates 22 and the second storage boxes 2 may be fixed to each other, and the second cover plates may be fixed to each other.

In practical application, the outer walls of the bottom surfaces of the first storage box 1 and the second storage box 2 are smooth and flat, so that the flatness when the first storage box and the second storage box are unfolded to serve as a test bench surface is met. Generally, the outer walls of the bottom surfaces of the first storage box 1 and the second storage box 2 are coated with anticorrosive coatings, so that the first storage box has high wear resistance and high acid and alkali corrosion resistance, and meets the working table standard of a professional laboratory. The anti-corrosion coating may be an epoxy resin coating with a thickness of 13mm, or may be other anti-corrosion materials according to needs, and this embodiment is merely an example.

In order to facilitate the operation of operators after the test box is folded, handles are arranged on the outer walls of the side surfaces, opposite to the pivoting positions, of the first storage box 1 and the second storage box 2.

Generally, in order to facilitate the visual distinction of the instruments or medicines in the second storage tank 21, a label is attached to each second cover plate for marking the name of the instrument or medicine stored in the corresponding second storage tank 21.

Further, in order to more stably support the whole test box on the ground after being unfolded in use so as to meet the complex working environment on site, as shown in fig. 1 and 3, at least two telescopic supporting legs 6 symmetrically arranged are respectively hinged in the first storage box 1 and the second storage box 2, and supporting leg accommodating spaces 61 are respectively reserved in the first storage box 1 and the second storage box 2.

Specifically, as for the number of the telescopic support legs 6, two telescopic support legs 6 are provided in the first storage box 1 and the second storage box 2, respectively, in this embodiment, for example, as needed. When the test box is used, after the test box is unfolded, each telescopic supporting leg 6 is bent and unfolded to a position perpendicular to the bottom surface of the first storage box 1 or the bottom surface of the second storage box 2, and then the test box is stretched and adjusted to a proper height, so that the test can be started. After the experiment, can withdraw telescopic supporting leg 6 to the shortest, then can all put back the supporting leg after buckling and accomodate in accomodating space 61, it is more convenient to operate. The height of the telescopic supporting leg 6 can be adjusted at will, and the specific structure for realizing the telescopic effect is the prior art, which is not described in detail herein.

In actual use, in order to make the telescopic support leg 6 more stable when supported, as shown in fig. 7. The whole test box also comprises fixing rods 7 the number of which is the same as that of the telescopic supporting legs 6, and a fixing rod accommodating space is reserved in the second storage box 2. One end of each fixing rod 7 is detachably connected to the corresponding telescopic support leg 6, and the other end is detachably connected to the side surface of the first storage box 1 or the side surface of the second storage box 2.

In detail, as shown in fig. 7, 8 and 9, a locking groove 71 is formed on each of the two side walls of each fixing rod 7, and a locking block 8 is respectively disposed on each of the side wall of the telescopic supporting leg 6, the side surface of the first storage box 1 and the side surface of the second storage box 2, and each locking block 8 can be locked in the locking groove 71.

Thus, when in use, after each telescopic supporting leg 6 is adjusted to a proper height, the two ends of the fixing rod 7 are respectively fixed on the telescopic supporting leg 6 and the side surface of the first storage box 1 or the side surface of the second storage groove 21, and the fixing rod 7 is obliquely arranged and forms a triangle with the side surfaces of the telescopic supporting leg 6 and the first storage box 1 or the side surface of the second storage groove 21, thereby further playing a role in enhancing the structural stability. After the test is finished, the fixing rod 7 can be detached and then placed back to the fixing rod accommodating space for accommodating, and the test is more convenient.
