For fermentation under microaerophilic conditions, the BioLector system is equipped with a special O2 down-regulation module. It consists of an additional gas connection for nitrogen on the backside of the BioLector and an oxygen sensor inside the cultivation chamber.
The sensor continuously measures the oxygen level inside the chamber and automatically regulates the flow of nitrogen into the chamber. In this way, an oxygen level between 2 % and 21 % can be generated in the chamber.
Independent of the additional module, all standard features of the microbioreactor remain unchanged.

Up to three additional fluorescence modules can be added to the standard filters for biomass, pH, and DO. In total, six different modules fit into the system.
