Principle of Operation As gas is produced in a sealed reactor, the pressure in the reactor increases. The same sensor that detects the vacuum created during aerobic operation, senses the increase in pressure and sends a signal through the DACS to release a pulse of gas to return the reactor to its starting pressure. This is accomplished by attaching the vacuum source to the Comput-OX in place of the regulated oxygen supply. These tubes are filled with user provided dessicant.
Gas is released from each reactor to a common vent.
The user must provide connection to a suitable fume hood or other means of evacuating these gasses, if they are not to be collected for subsequent analysis.
