NextGen-O2k Fluo

The complete experimental system for high-resolution respirometry (HRR), including fluorometry, allowing simultaneous monitoring of oxygen consumption together with either H2O2 production (AmR), mt-membrane potential (TMRM, Safranin and Rhodamine 123), Ca2+ (CaG) or ATP production (MgG).

Product ID: 10103-03

The NextGen-O2k Fluo enables the following O2k-Applications:

  • oxygen consumption
  • H2O2 production
  • ATP production
  • Ca2+
  • mitochondrial membrane potential

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

This package is available as a Power Package to increase throughput. Certain auxiliary tools and services are not included in Power Packages, more details:

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.
