“I use the BF/OT/E PO2 E-series sensor to measure PaO2 in vivo in invertebrates during external environmental fluctuations in PO2. Due to the accuracy and reliability of the PO2 probes we can design experiments that provide real time measurements of PO2 during changes in environmental variables and more accurately link this to behavioural responses. During the experimental set up the staff at Oxford Optronix were always on hand to help out with any technical queries and even visited the laboratory to check out the experimental set up and ensure the probes were working. I would recommend Oxford Optronix to anyone with an interest in measuring PO2 and temperature in marine science.”

The survival of tissues and organs relies on an adequate supply of oxygen. The measurement of tissue oxygen tension (ptiO2) provides a direct measurement of the balance between oxygen supply (by the blood) and metabolic oxygen consumption (by the tissue), i.e. a readout of oxygen availability at the cellular level. This is in contrasts to spectroscopy (NIRS) techniques, which merely describe haemoglobin oxygenation status.  

Our OxyLite™ oxygen monitors will be of interest therefore to life scientists wishing to directly and continuously measure dissolved oxygen in the normal physiological as well as hypoxic ranges, both in experimental in vivo models, or in any number of in vitro applications. 

Since 1998, when Oxford Optronix pioneered the commercialization of fibre-optic oxygen micro-sensor technology, the OxyLite™ brand has become established the world over in biomedical, boasting in excess of 500 peer-reviewed journal citations and hundreds of units sold worldwide. 

2013 saw the culmination of a decade and half of continuous R&D with the launch of our third-generation of tissue oxygen monitors. Blending contemporary design, true plug and play convenience and the very latest in opto-electronic technology, our OxyLite™ Pro systems provide what is simply the most advanced, accurate and reliable tissue oxygen monitoring platform on the market. 

Our oxygen sensors leverage state-of-the-art optical fluorescence technology intended for the quantitative measurement of oxygen partial pressure (pO2) and temperature in tissues, physiological fluids, cell cultures and other in vitro applications.  This technology offers key advantages over devices based on polarographic technology, making our oxygen monitors much easier to use and ideally suited to oxygen measurements in the typical physiological range, as well as incredibly sensitive under conditions of hypoxia. 

Applications include cancer biology, angiogenesis, stroke and brain injury, vital organ and muscle tissue monitoring, flap monitoring, ophthalmology, wound healing, as well as dissolved oxygen monitoring in cell culture, bioreactors etc.
