The YM-GHX-VZ series photochemical reactor was successfully developed with the technical support of multiple professors from Shanghai Jiao Tong University and East China University of Science and Technology. It is mainly used to study photochemical reactions under conditions such as gas or liquid media, fixed or flowing systems, ultraviolet or simulated visible light, and whether the reaction vessel is loaded with TiO2 photocatalyst. $r $n has functions such as providing samples for analyzing reaction products and free radicals, determining reaction kinetic constants, and measuring quantum yields. It is widely used in research fields such as chemical synthesis, environmental protection, and life sciences
