has bioreactor scale bioreactor minibioreactor scale Kuhner TOM bioreactor A shaken bioreactor online monitoring system called TOM that is produced by Kuhner. It has minibioreactor scale that measures oxygen transfer rate, carbon dioxide transfer rate, and respiratory quotient in parallel shake flask or microtiter plate cultivations by automated analysis of respiratory gas exchange during orbital shaking incubation. This system is classified under bioreactor because of its use in conjunction with biological cultivation workflows. The Kuhner TOM is not strictly a bioreactor in the Rather, it is an online respiratory gas monitoring and analytical system that measures oxygen transfer rate, carbon dioxide transfer rate, and respiratory quotient in cultures grown in orbitally shaken vessels such as shake flasks or microtiter plates.
