IOC53 International Workshop on High-Resolution Respirometry


30 July - 4 August 2009, 53rd IOC - International Course on High-Resolution Respirometry. Hotel Tannberg, Schroecken, Vorarlberg, Austria. 

The 53rd O2k-Course is the 20th presentation of high-resolution respirometry (HRR) in Schröcken since 1988, for the first time extended to four full days. The O2k-Course includes experiments with biological samples, providing a practical overview of the Oxygraph-2k, with integrated on-line analysis by DatLab 4.3 (new upgrade), applications of the TIP-2k, and perspectives of high-resolution respirometry in mitochondrial physiology. Emphasis is placed on hands-on applications by all participants.

        Experienced tutors guide small working groups step-by-step through the approach of HRR. Five Oxygraph-2k (10 chambers) are available for a do-it-yourself application of both hardware and software.  Combined with an introduction and demo experiment, it is best to put the O2k into action yourself.

        During lunch breaks, sufficient time is available for relaxing walks and talks, to enjoy the refreshing scenery of the alpine environment, or use the spare time for specific tutorials. With DatLab 4.3 we accomplish data analysis on-line during the experiment, providing final results and their graphical presentation by the end of an experimental run. Thus we gain sufficient time to demonstrate MultiSensor perspectives, see the Titration-Injection microPump TIP-2k with new feedback-control in action and practice its simple and automatic operation.
