O2k-FluoRespirometer

The complete experimental system for high-resolution respirometry (HRR), including fluorometry, the TIP2k and the O2k-sV-Module 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).

In addition to the included O2k-Modules (TIP2k-Module, O2k-sV-Module and O2k-Fluo Smart-Module), the O2k-FluoRespirometer supports all add-on O2k-Modules: 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.

O2k-Applications:

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

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

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.
