Note: Titration of chemicals in respirometry

Overshoots or short interruptions of the flux after the injection of chemicals do not have a meaning in respirometric measurements. A disturbance of the signal is only observed due to the injected chemical and does not represent mitochondrial respiration. With the addition of a chemical solved in ethanol a little bit of oxygen is always introduced, since ethanol has higher oxygen solubility than water.
After a titration, it is common to observe liquid accumulated on top of the stopper receptacle. When this happens, we recommend removing this excess of liquid as it can lead to O2 backdiffusion into the chamber. For this, we recommend using the ISS, placing the tip close to the capillary, but not directly on top of it.

Further information

  • Safety information: fixed needles are used with rounded tips, not usable for injection into tissues.
  • Hamilton microsyringes are specifically produced for O2k-titrations and can be ordered directly from Oroboros Instruments to assure exact fitting with the O2k-Stopper and O2k-Chamber dimensions.
  • Visit also: Hamilton.
  • Eliminate rough edges with 3M™ Wetordry™ Paper Sheet P1000 by gentle rubbing.
  • Use a cleaning wire for the needle. If a syringe is clogged , sometimes it is also helpful to fill it from the back with EtOH or H2O and try to press the plunger gently down.
