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.

Other Optional Modules
The combination of multiple modules is possible.
/// Gas Modules
- O2 up regulating module for up regulation of oxygen up to 35 %
- CO2 up regulating module for fermentation with CO2 controlled gas atmosphere
- Anaerobic cultivation module for cultivation under anaerobic conditions
/// Fluorescence Modules
- LED / filter module for fluorescence measurements for wavelengths between 365 nm - 800 nm
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.
