The new Biotool Swiss PetriSphere Gas-System is consisting of a microprocessor-based controller connected with a diaphragm vacuum pump and a nitrogen gas reservoir. The necessary vacuum, the gas exchange pressure and the number of cycles can be programmed at the keypad of the controller. By simply pressing the start button the process starts and runs fully automatic.

The container will be evacuated to the pressure adjusted, vented with the reaction gas connected to the system and the pre-programmed number of cycles is processed automatically. No additional chemicals are needed to create an anaerobic atmosphere.
