Specifically, in fig. 1, the reactor 100 is shown in perspective, with the broken line portion being a blocked structure and the solid line portion being a unblocked structure. The reaction test tubes 101 may be set to conventional test tubes such as test tubes with a diameter of 16mm or 25mm, the number of the reaction test tubes 101 may be set according to actual demands such as 3, 5 or 8, and the size of each reaction test tube 101 may be set according to actual conditions such as setting the diameter of 2 reaction test tubes 101 to 16mm and the diameter of 3 reaction test tubes 101 to 25mm.
