Startup O2k-Respirometer

O2k-Catalogue

Description Startup O2k-Respirometer - the experimental system complete for basic high-resolution respirometry (HRR). The O2k-Respirometer 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, the O2k-Titration Set, and for performing high-resolution respirometry with reduced amounts of biological sample the O2k-sV-Module.

The O2k-Respirometer supports all add-on O2k-Modules of the Oroboros O2k, and is a component of the O2k-FluoRespirometer.

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.

O2k-sV-ModuleO2k-sV-Module: Now included in all O2k-Packages, comprised of Duran glass chambers of 12 mm inner diameter specifically developed to perform high-resolution respirometry with reduced amounts of biological sample, and all components necessary for smaller operation volume (V) of 0.5 cm3 (0.5 mL). Current DatLab version is included in the delivery of this revolutionary module.

The O2k-sV-Module is compatible with all O2k-Series and it is designed specifically for respirometry using small amounts of sample.

The O2k-sV-Module cannot be used for simultaneous measurement of multiple parameters in the O2k-FluoRespirometer or in combination with the O2k-MultiSensor Modules.

ISS-Integrated Suction SystemISS-Integrated Suction System: Suction pump 230 or 120 V with stainless steel housing, 2 liter waste bottle, filter and tubing; for siphoning off excess medium from the O2k-Stopper and for emptying the O2k-Chambers. The ISS is included as a standard component of the O2k-FluoRespirometer. Media containing living cells or microorganisms, various poisons (inhibitors, uncouplers) and mixtures of proteins and substrates are safely disposed off in the 2-litre waste bottle.

The suction pump (230 V or 120 V) is enclosed in a stainless steel housing, which holds a readily accessible mains switch, two removable receptacles for the tip of the tubing, an easily removable and safe connection to the gas filter which further connects to the fully stabilized waste bottle. The waste bottle with filter can be simply removed for emptying, cleaning and drying.

For specific country configurations, see Product ID 28101, 28102, 28103.

OroboPOSThe OroboPOS is a polarographic oxygen sensor (POS), with an amperometric mode of operation. The OroboPOS meets the highest quality criteria in terms of linearity, stability and sensitivity of the signal. The Clark type polarographic oxygen sensor (POS) remains the gold standard for measuring dissolved oxygen in biomedical, environmental and industrial applications over a wide dynamic oxygen range. It consists of a gold cathode, a silver/silverchloride anode and a KCl electrolyte reservoir separated from the sample by a 25 µm membrane (FEP). The main body of the OroboPOS is made of PEEK. With application of a polarization voltage (0.8 V), a current is obtained as an amperometric signal, which is converted to a voltage.26000-01
