The BioOxy 50μm active area diameter tip expands researchers’ capabilities of discovery with sensing O2 in critically small spaces.
A new and innovative technology for measuring oxygen in gaseous and aqueous phase with important advantages over using common Clark type electrodes.
- BioOxy does not consume oxygen during measurements
- Similar performance overall at a lower cost. This helps lower research or operational expenses compared to competitive consumable sensors
- BioOxy can be gamma sterilized
The BioOxy Couples directly to either the Fiber Optic OXY-MICRO Microsensor Oxygen Meter or the FLOX-Oxygen monitoring System.

The BioOxy is ideally adapted for examination of small sample volumes thanks to its miniature sensor tip diameter of less than 50μm. The BioOxy is well suited for long-term measurements and biotechnological applications. The signal does not depend on the flow rate of the sample and the measurement principle requires no contact.
The physical principle is based on quenching of luminescence, which is caused by the collision between molecular oxygen and a luminescent dye molecule in the excited state. There is a direct relationship between the measured phase angle and oxygen concentration. The phase angle decreases when oxygen is present in your sample. The transfer of the emitted light signal is done optically using high quality fused silica fibers, ensuring a contact performance lot-to-lot.
