Oroboros O2k-Core (O2k-Series D - G)


Description Oroboros O2k-Core (O2k-Series D - G) - the experimental system complete for basic high-resolution respirometry (HRR). The O2k-Core includes the O2k-Main Unit with stainless steel housing, O2k-Assembly Kit, two OroboPOS (polarographic oxygen sensors) and OroboPOS-Service Kit, DatLab software, the ISS-Integrated Suction System and the O2k-Titration Set. The O2k-Core supports all add-on O2k-Modules of the O2k.

On-line display of oxygen flux (rate of respiration) is provided in addition to the conventional 'oxygraphic' plot of oxygen concentration over time. Highest signal stability minimizes the required amounts of biological sample, and provides the basis for resolution in the extreme low-oxygen range. Peltier temperature control provides a thermal stability at ±0.002 °C in the range of 4 °C to 47 °C at typical constant room temperature. Electronically controlled PVDF or PEEK stirrers are integrated in the two-chamber design of the O2k, and a barometric pressure transducer enables automatic oxygen calibrations implemented in the DatLab software.

The O2k is a sole source apparatus with no other instruments meeting its specifications.
