The choice of the evacuation and replacement method results in customer advantages.

• It is very fast, which reduces the time of exposure to Oxygen-rich air. This improves recovery of oxygen-sensitive organisms.
  
• Instead of flushing out the Oxygen, the air is replaced from a confined environment thus limiting the consumption of gas. This saves cost and handling, and there is no need for very big cylinders in the laboratory.
  
• No disposables are used, so the user does not handle chemical waste.
  
• The created environment is dry. Handling is cleaner, it avoids the risk of cross-contamination and makes identification, colony-count and pick-up for secondary inoculation easier. The humidity in the jar can however be increased.
  
• As the system operates fully automatic, it is possible to exactly repeat the process so that absolute reproducibility can be achieved. Also any human errors can be eliminated.
  
• A quality assurance process runs automatically BEFORE incubation. It guarantees that no fall-out can happen because of system or jar failure. The user is certain of microbial growth during incubation.
  
• This desktop system has a small footprint, so that it does not waste valuable laboratory space.
  
• The system needs very little maintenance.
