The anaerobic box is specially designed for the cultivation and research of anaerobic microorganisms, adopting an air - tight structure and a gas replacement system. The outer shell is made of thick metal materials to ensure good air - tightness and pressure resistance, and the interior is equipped with temperature and humidity regulation and lighting systems. By filling the box with a mixture of nitrogen, hydrogen, and carbon dioxide and expelling oxygen, it creates a low - oxygen or oxygen - free environment. Its advantage lies in its ability to precisely control gas composition, temperature, and humidity, providing a stable growth environment for anaerobic microorganisms. It is easy to operate, with parameters settable via the control panel. It has high safety, featuring gas leakage detection and alarm devices. It is widely used in fields such as microbiology research, food fermentation, and sewage treatment, helping to further explore the characteristics and applications of anaerobic microorganisms.
