Unisense MicroOptode - Oxygen Optical Sensor System
FromUnisense A/S
Unisense now offers optode sensor technology with full integration to our existing laboratory systems. The optical sensor technology gives you a cost-effective and robust oxygen sensor that can be applied a great number of applications. Simple two-point calibration and temperature compensation ensures ease-of-use, and the Unisense software suite allows you to combine the oxygen MicroOptode with our wide selection of microsensors (e.g. H2, H2S, N2O, NO, pH, redox and more).

The oxygen optode is designed for research applications within:
- Respiration
- Biomedical
- Bulk and Bioreactors
- Environmental sciences
- Profiling
The measuring principle of the oxygen optode is based on the latest optical fiber technology. By quenching of the luminescence caused by collision with oxygen molecules, the oxygen concentration can be determined. More oxygen molecules will result in a lower emission signal, giving a measure of the oxygen concentration in the sample.
The optode fiber is build into a steel needle; this allows you to retract the fiber into the needle for complete protection e.g. when piercing a rubber septum. When the needle tip reaches the measuring site, the fiber can be pushed out into the sample and measure the oxygen concentration.
