Startup O2k-Respirometer - Oroboros Instruments

The Startup 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 Startup O2k-Respirometer does not include, but fully supports O2k-Fluorometry and the O2k−Modules: TIP2k, pH, TPP+, NO.

Additional information

Oxygen	Respiration chambers with minimum oxygen diffusion • High-resolution of oxygen flux: ±1 pmol O₂ ∙s⁻¹∙mL⁻¹ in normoxia to anoxia • High-resolution of oxygen concentration: 5 nM • Long-term stability and linearity of the polarographic oxygen sensor (OroboPOS) • Barometric pressure transducer for accurate air calibration at any altitude
SUIT protocols	Standardized substrate-uncoupler-inhibitor-titration DL-Protocols • Real-time monitoring of respiratory rates and states • Multiple titrations within a single assay for in-depth analysis of mitochondrial fitness
MultiSensor	Additional parameters recorded real-time in combination with oxygen in the same chamber • Automatic and documented calibration routines, instrumental background tests, and mitochondrial assays supported by DL-Protocols
Temperature	4 to 47 °C; stability ±0.002 °C
Thermostat	Peltier temperature control
Chamber	Material: Duran glass Volume: 2 mL or 0.5 mL
Specialized DatLab Software	For use on a Windows PC connected to the O2k via a USB port
Max. power input	120 W
Current at 100-120 V	max. 1.0 A
Current at 220-240 V	max. 0.5 A
Power consumption	During standard operation (when block temperature is stable at 37 °C and ambient temperature of 22 °C) approx. 24 W
Lab space required	The O2k requires a minimum of lab space (0.5 m bench space) next to an external PC or laptop, with sufficient space for the ISS, Titration Set and handling. For maximum signal stability and optimal temperature control, the O2k should be placed in a position in which it is not exposed to direct sunlight and sudden changes of room temperature. Keep the space on the table below the O2k bottom clear to prevent any interference of ventilation beneath the O2k-Main Unit.
