Description

Technical Field

[0001] This utility model relates to the field of photochemical reactions, and in particular to a laboratory-grade temperature-controlled photochemical reaction device. Background Technology

[0002] Traditional photochemical reaction apparatuses commonly used in laboratories are large in size, with crude and rudimentary heat dissipation from the light source. The temperature control conditions of the reaction vessel are poor or nonexistent, making it prone to side reactions due to large temperature fluctuations and generating many impurities. Alternatively, the temperature control of the reaction vessel requires external equipment, resulting in poor temperature control coordination. This makes it impossible to automatically control and adjust the corresponding parameters during the photochemical reaction experiment, leading to uncontrollable reaction processes, large errors in reaction results, and affecting the smooth progress of experimental conclusions and research directions.
