NextGen O2k-Respirometry and PhotoBiology

The NextGen-O2k Respirometry and PhotoBiology package is the complete experimental system for PhotoBiology studies.

Coming soon

The NextGen O2k-Respirometry and PhotoBiology enables the following O2k-Applications:

  • oxygen consumption
  • photosynthesis
  • light-enhanced dark respiration

The NextGen O2k-Respirometry and PhotoBiology also supports all add-on O2k-Modules: Q-Module, NADH-Module, O2k-TPP+ ISE-Module, O2k-pH ISE-Module, O2k-NO Amp-Module, enabling redox state measurements, measurement of mt-membrane potential with ion sensitive electrodes (ISE for TPP+ or TPMP+ ) or pH.

Additional information


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


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


4 to 47 °C; stability ±0.002 °C


Peltier temperature control


Material: Duran glass
Volume: 2 mL or 0.5 mL

Specialized DatLab Software

Installed on integrated computer for protocol design, control and data analysis

Max. power input

330 W

Current at 100-120 V

max. 3.0 A

Current at 220-240 V

max. 1.5 A

Power consumption

During standard operation with screen (when block temperature is stable at 37 °C and ambient temperature of 22 °C) approx. 45-50 W

Lab space required

The O2k requires a minimum of lab space (0.5 m bench space), 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.
