Startup O2k-Respirometer

O2k-Catalogue

Description O2k-Core (OROBOROS Oxygraph-2k Core) - 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 Titration Set. The O2k-Core supports all add-on O2k-Modules of the Oxygraph-2k.

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 ±0.001 °C in the range of 2 °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.

The O2k-Core[1] does not include, but fully supports and is required for the add-on Modules of the Oxygraph-2k, such as the TIP2k, O2k-Fluorescence Module, O2k-TPP+ and Ca2+ Electrode Module (ISE), O2k-pH ISE-Module, O2k-NO Amp-Module.

  1. A PC is required (not included), connecting DatLab to the O2k via a USB port. Minimum requirement: Pentium III, 256 MB, Win 2000™ or Win XP™.
