Multiple O2k-units are offered as a Power O2k-Respirometer system for high-resolution combined with high-output. Many O2k-Network Labs have increased their high-resolution high-output by multiple O2k-units, using two to 12 O2k (4 to 24 O2k-Chambers).

This application does not require an additional ISS-Integrated Suction System, an O2k-Titration Set and the O2k-Manual.

The Power O2k-Respirometer supports all add-on O2k-Modules of the Oroboros O2k.

O2k-Applications:

  • oxygen consumption

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.
