Embodiment 1

[0025] Such as figure 1 , 3 As shown, the light box part, a cuvette dark box for experiments includes a light box 100 , a control box 200 , and a sample injection box part 300 . There is a stepping motor 101 on the top of the light box part 100, and the shaft of the stepping motor 101 has a light blocking part 103, specifically a light blocking plate 103A, and the light blocking plate 103A can block light from entering the Light box 100. There is a detachable cover plate 102 on the side of the light box 100, and the detachable cover plate 102 can be installed on the top of the light box 100 in this state when the side of the light box 100 with the light baffle plate 103A is perpendicular to the desktop. There are fixed slide rails 104 ( figure 1 Not shown in) and moving slide rail 105 ( figure 1 Not shown in), the inner wall of the light box has a reflective coating or a mirror. The moving slide rail 105 can reciprocate on the fixed slide rail 104 . One end of the moving...

Embodiment 2

[0030] Such as figure 2 , 3 As shown, the light box part, a cuvette dark box for experiments includes a light box 100 , a control box 200 , and a sample injection box part 300 . The light box part 100 has a light-shielding part 103 in the right view direction, specifically an electrochromic sheet 103B, and the electrochromic sheet 103B can switch between transparent / opaque states when the power is turned on / off. There is a detachable cover plate 102 on the top of the light box 100, and the detachable cover plate 102 can be installed when the side of the light box 100 with the electrochromic sheet 103B is parallel to the desktop. The right side view of the light box 100 in this state Direction to achieve the purpose of no light entering the light box 100 in the direction of the right side view, the inner wall of the light box has a reflective coating or a mirror surface. The light box 100 has a fixed slide rail 104 and a movable slide rail 105 inside. The moving slide rail ...

Abstract

The invention relates to the field of laboratory equipment, in particular to a cuvette cassette for experiments. An illumination box, a control box and a sample injection box part are included; the problems that the cuvette placement position, the incident angle and the irradiation duration cannot be ensured to be consistent and the cuvette is easily knocked down by manual operation in the laser irradiation step of the active oxygen substance determination experiment can be solved, and active oxygen substance determination can be accurately, conveniently and quickly carried out by using the cassette provided by the invention. During use, a laser is aligned with the center of one surface of the illumination box, which is provided with the light blocking part, a cuvette filled with a sampleis put into a square groove at one end of the movable sliding rail and is slightly pushed into the illumination box, and the light blocking plate is controlled by setting the illumination box.

Description

technical field [0001] The application relates to the field of laboratory equipment, in particular to an experimental cuvette dark box. Background technique [0002] Active oxygen species are the products of oxygen molecules with electrons, including the one-electron product of oxygen, oxygen anion, the two-electron product hydrogen peroxide, the three-electron product hydroxyl radical, nitric oxide, etc., with a short half-life. A method commonly used to detect reactive oxygen species in biochemical experiments is: 1,3-diphenylisobenzofuran (DPBF) is used as a singlet oxygen probe, and methylene blue (methylene blue trihydrate, MB) is used as a reference (in in dichloromethane). DPBF and the sample to be tested are dissolved in dichloromethane and loaded into a cuvette, and the concentration of the solution is adjusted so that the maximum absorption of the UV-Vis-NIR spectrophotometer of DPBF is around 1.3, and the maximum absorption of the sample to be tested is around 0....
