Abstract: A nitrogen cabinet is disclosed to include at least one cabinet body having a door and a nitrogen inlet connected to a nitrogen supplier, multiple shelves mounted inside the cabinet body and defining multiple storage spaces, multiple containers mounted in storage spaces, each container having at least one gas charging port and an identification device, and multiple gas-charging units mounted inside the cabinet body and respectively connected to the nitrogen inlet for charging the containers with nitrogen. Thus, the nitrogen cabinet combines the functions of storage, charging, management, identification, and tracing of the containers, thereby lowering the chance of oxidation or contamination of storage items in the containers and effectively controlling real-time inventory data to improve product yield rate.
