The new aeration system of the Biostat® A provides continuous automatic flow control over the full range of each gas used. As a result, Biostat® A does not require any manual adjustment of flow meters and therefore eliminates problems with pulsed aeration. Setting up the bioreactor is straightforward: Just connect the aeration tubing, configure the aeration profile, enter the DO setpoint – that’s it! For cell culture applications, interfaces for four gases (air, O2, CO2 and N2) are available for DO and pH control. The microbial version features two gas lines (air and O2) for DO control.
