The invention relates to the technical field of experimental equipment, and discloses a chemical experiment tube placement rack. The rack comprises a base, a battery is fixedly mounted by a bolt in the base, at least two independently operated push button switches electrically connected to the battery are fixedly mounted on the base, a lower matching seat is fixedly mounted by a bolt on the upperside of the base, and an upper matching seat is mounted on the upper side of the lower matching seat through a bearing. The tube placement rack can effectively place, clean and dry tubes according tothe use requirement of the tubes, thereby effectively facilitating the maintenance work of the tubes, reducing the physical strength consumption of experimental operators, providing convenience for the experiment operators to mark and select the tubes, saving the experiment preparation time, and improving the experiment efficiency, and the rack has a high practical value.
