Temperature control type flowing thin-layer and frequency spectrum electrochemical in-situ reaction tank

The utility model provides a temperature control type flowing thin-layer and frequency spectrum electrochemical in-situ reaction tank. The reaction tank comprises a light transmitting component, an electrode sealing component, a heating insulation component, a sealing component and the like, wherein the electrode sealing component is connected with the peripheral heating insulation component through a screw thread, and the adjustment of the distance between an electrode sealing disc and an optical lens on the top is realized by adjusting the screw thread. An optical tank can realize the thickness and temperature adjustment of the reaction tank, and most application demands can be met.
