Oroboros Instruments—as a driving force in mitochondrial physiology—extends the analytical and diagnostic power of high-resolution respirometry by integration of (i) a Q-Redox Module and (ii) a PhotoBiology Module in the NextGen-O2k. The NextGen-O2k is a MultiSensor all-in-one instrument for in-depth studies of the mitochondrial role in human diseases, and mitochondria and chloroplasts ability in regulating algal growth and metabolite production. In just one device researchers obtain a snapshot of the mitochondrial/chloroplast metabolic profile, saving on experimental time, reagents and samples, minimizing errors and ensuring reproducible and accurate results. Substrate-uncoupler-inhibitor titration protocols can be found with the SUITbrowser according to a large diversity of research questions. These SUIT protocols are integral to the DatLab software, which then guides the user through sequences of titration steps and numerous respiratory states in a single assay. In addition, the instrument offers the highest oxygen sensitivity (5 nM detection limit) with an exceptional resolution (wide oxygen concentration range, between 0-1000 μM) and robustness (>10 years lifespan), being superior to any other market option.


We aim at establishing the Oroboros quality control management for dissemination to our worldwide O2k-Network laboratories. This will become an effective contribution to address the acute reproducibility crisis of scientific investigation. In the spirit of Open Science and global networking, we support the COST Action CA15203 MitoEAGLE project to enable data sharing across projects and institutions in an Open Access database on mitochondrial physiology and pathology, to resolve the inflation crisis and ultimately the value-impact crisis of present academic publication. This will enhance key developments in mitochondrial medicine. In addition, we expand our business to algal biotechnology and ecology with the PhotoBiology Module of the NextGen-O2k, widening our focus from medicine to environment and climate.
