Abstract: A thermal decompression control device for glass containers for magnetic fluid mixing liquid, comprising a glass container, and an inside of the glass container is filled with magnetic fluid mixing liquid. An outer edge of the glass container comprises an extended and protruding cylinder, and the glass container is connected with a soft silicone tube by the cylinder. The soft silicone tube is formed into a hollow cylinder with one end open and the other end sealed, wherein the open end of the soft silicone tube is tightly socketed with the protruding cylinder of the glass container. The protruding cylinder of the glass container is a hollow cylinder communicating with the inside of the glass container. The intersection of the soft silicone tube and the glass is sealed.
