1. Oxygen removal and maintenance

Vacuum replacement: Inject a mixture of nitrogen, hydrogen, and carbon dioxide into the low-pressure chamber by vacuum dropping the oxygen concentration to below 1%, and repeat multiple times to completely eliminate oxygen.

Catalytic deoxygenation: Using palladium catalyst to react hydrogen with residual oxygen to generate water (2H ₂+O → 2H ₂ O), achieving a deep anaerobic state.

Gas regulation system: Accurately control the gas ratio inside the box and simulate a natural anaerobic environment.

2. Environmental stability control

Temperature: Constant temperature inside the chamber is achieved through gas convection, with an error of ± 0.5 ℃, to avoid damage to the culture dish caused by temperature differences.

Humidity: Maintain stable humidity (usually 60% -80%) to prevent condensation water pollution or bacterial colony disappearance caused by evaporation of the culture medium water.

Pressure balance: Maintain a slight positive pressure through the intake/exhaust valves to prevent external air from infiltrating.

3. Pollution Prevention and Biosafety

Disinfection function: Supports UV disinfection and strong oxidant disinfection to ensure the sterility of the internal cavity.

Biological detoxification: equipped with a metabolic waste gas removal device to prevent the accumulation of waste gas and inhibit bacterial growth.

Anaerobic biological incubatorThe structural composition of:

1. Operating room: It is the main area for anaerobic operations and cultivation. The interior is made of stainless steel materials for easy cleaning, and some are equipped with 220V sockets for easy access to other equipment.

2. Sampling room: used for the entry and exit of samples, first evacuate and then fill with oxygen free gas to avoid oxygen fluctuations in the main compartment.

3. Gas path system: It can accurately adjust the flow rate and input various required gases. The gas path switch adopts a locking switch to control the solenoid valve.

4. Circuit control system: Adopting a microcomputer intelligent program controller, touch sensitive buttons, the screen accurately displays various parameter indicators such as internal temperature and pressure, and has functions such as power-off memory and overpressure self release.
