O2k specifications

O2k-Catalogue

Description O2k versus multiwell respirometer: O2k stands for Oroboros O2k and high-resolution respirometry, meeting powerful quality criteria securing high output and pioneering state-of-the-art comprehensive OXPHOS analysis of substrate control and coupling control of mitochondrial function. 'High throughput' stands for disposable multiwell systems - expensive, with limited scope and extremely high running costs. In respirometry, high throughput is not equivalent to high output. If you’re using a biased instrument, it doesn’t matter how many measurements you take – you’re aiming at the wrong target (Silver 2012 Penguin Press).

Combination of interests

Erich Gnaiger is founder and CEO of Oroboros Instruments, and responsible for the development of the O2k in collaboration with the O2k-Team and our partners. A series of methodological publications is the result of positive feedback between his work as faculty staff of the Medical University of Innsbruck, his company initiatives and numerous international cooperations.
