The high-pressure intermediate container is an auxiliary component of experimental equipment, which can be divided into ZR-1~ZR-6 according to different usage scenarios, volume size, pressure size, temperature resistance, and material corrosion resistance. Its structure also varies depending on the usage scenario; Conventional volumes ranging from 200mL to 10L cannot be used, and larger containers can be customized according to requirements; The temperature resistance range of a container is related to its structure and material. Taking ZR-3 piston container as an example, the normal temperature resistance is room temperature~180 ℃. If it exceeds the range, it needs to be explained in advance; The corrosion resistance of containers is related to their usage scenarios and materials. Steel containers have general corrosion resistance, and according to the requirements of component usage, the corrosion resistance of containers can be improved by selecting materials or using targeted lining methods. Organic glass containers are more commonly used in vacuum treatment, allowing for a visual inspection of the internal condition.
