From Bioblast



to explore the Power of Life
Thank you for your interest in the Oroboros O2k – the modular two-chamber system for high-resolution respirometry (HRR). The O2k-FluoRespirometer is the O2k complete for high-resolution respirometry combined with fluorometry - user-friendly and ready for application.
The O2k-FluoRespirometer includes the Titration-Injection microPump (TIP2k) and supports optional add-on O2k-Modules, which can be added any time according to application-specific requirements: Various electrodes are available (TPP+, pH), and sensors are supported (such as NO, H2S). Auxiliary O2k-Tools complete the package for mitochondria and cell research.

Low running costs

High output - low running costs
  • Annual costs for O2k-spares are less than € 1,000 based on long-term experience with the O2k (e.g. spare glass chamber, stoppers.
  • The low amount of biological sample required for the O2k can be even further reduced by using the new and economical O2k-sV-Module.
  • The OroboPOS sensor has a warranty of 24 months and a typical life span of more than 10 years. Nevertheless, a spare OroboPOS is included in the O2k-FluoRespirometer for immediate replacement in case of service requirements. For OroboPOS sensor service, see O2k-Videosupport and O2k-Manual.
  • A OroboPOS membrane replacement is not required over periods of several months. Other small parts such as sealing rings or gaskets do not need to be replaced for one year or more. The costs are therefore calculated at less than € 20 per year.
  • Less than 10% of all instruments sold worldwide needed to be sent our workshop for repairs, which speaks for a robust and durable instrument
  • MiR05-Kit: Calculate 5 mL per run with two O2k-chambers, this yields max. € 1.40 per run.
  • Other chemicals not supplied by Oroboros Instruments depend on the specific applications: substrates, uncouplers, inhibitors, specific effectors, fluorophores.
  • Washing with deionized or distilled water, with pure ethanol (removing inhibitors) and 70% ethanol (sterilization, storage).
  • In applications of specific O2k-Modules, spare sensors, e.g. the glass pH electrode, may increase the costs by € 700 to € 1,400 per year.
