Description

Technical Field

[0001] The utility model relates to the field of light reaction experiments, in particular to a multi-test tube light reaction fixing seat and a matrix light reaction device. Background Art

[0002] Photocatalytic reaction apparatuses are essential tools in photochemical reaction experiments. These devices typically consist of two parts: a holder that secures the test tubes and a light source. The holder stably holds the test tubes, ensuring they do not move or tilt during the experiment, thereby ensuring adequate illumination of the tubes and ensuring stable and repeatable reactions. The light source provides the necessary light energy to excite the photocatalyst and initiate the chemical reaction. Existing photocatalytic reaction apparatuses come in a variety of designs, and light sources of varying wavelengths and intensities can be selected to meet the specific needs of the experiment, meeting the requirements of different photochemical reactions.

[0003] Although existing photocatalytic reaction devices perform well in single-test-tube experiments, there are still some significant problems in practical applications. The main problem is that most existing photocatalytic reaction devices can only install one test tube and cannot uniformly illuminate multiple test tubes at the same time. This single-test-tube design limits the scale and efficiency of the experiment, especially when large-scale sample testing or parallel experiments are required. Researchers often need to conduct experiments test tube by test tube, which is not only time-consuming and labor-intensive, but may also lead to inconsistencies in experimental conditions, thereby affecting the reliability and comparability of experimental results. Therefore, the development of a multi-test-tube photoreaction holder and a matrix photoreaction device that can uniformly illuminate multiple test tubes at the same time has become an urgent need to improve experimental efficiency and data consistency.
