Thank you for your interest in the OROBOROS Oxygraph-2k – the modular two-chamber system for high-resolution respirometry (HRR). The O2k-Core is the Oxygraph-2k complete for HRR - user-friendly and ready for application.

The O2k-Core supports all optional O2k-Modules, which can be added any time - configuring the O2k-MultiSensor System according to application-specific requirements: The O2k-Fluorometer is the O2k-Core combined with the O2k-Fluo LED2 Module and the Titration-Injection microPump (TIP2k). Various electrodes are available (TPP+, pH), and sensors are supported (such as NO, H2S). Auxiliary HRR-Tools complete the package for high-resolution respirometry and mitochondrial physiology.
