The utility model discloses a micro chemical experiment reaction vessel, which comprises a vessel body and a reaction chamber. The vessel body is made of inorganic glass material with a smooth, flat, ripple-free and transparent surface and certain heat resistance, the reaction chamber is arranged on the vessel body, the edge size of the reaction chamber is generally 20 to 96 mm, and the depth of the reaction chamber is 0.1 to 2 mm. When the utility model is used in the experiment, only a small amount of reactant solution is required, and the reactants can gradually infiltrate into each other along the liquid film by applying flexible methods and simple experimental procedures. Therefore, the utility model can fully reflect the whole process of chemical reaction, help the students to observe clear, true, interesting and highly contrastive experimental phenomena, facilitate both the teaching and the improvement of the experimental skills of the students, and simultaneously benefit the environmental protection.
