Abstract The caffeine sublimation experiment is a classic experiment in university organic chemistry. Compared with traditional sublimation devices, the improved caffeine sublimation device has the characteristics of visible sublimation process, rime like crystal shape, high yield, and high repeatability, which enhances the fun and scientific rigor of the experiment. The introduction of caffeine’s birefringence phenomenon has stimulated students’ interest in science. In addition, we introduced the development process of the sublimation device into the classroom, and worked with students to analyze the problems that exist in the device improvement project, the causes of these problems, and the solutions to these problems, in order to experience the process of innovation.
