These integrated Disposable Optical Transducer (iDOT™) gamma-stable bag ports offer non-invasive monitoring and come pre-calibrated for plug-and-play use. Polestar’s iDOT sensor configuration allows for simple integration of pH and dissolved oxygen (DO) monitoring to single-use bags, including bioreactors. They feature a POE bag port with sensing film, using materials that meet USP Class VI requirements. These bag ports are designed to work with Polestar Technologies’ DSP series optical process monitoring products, where the bag port would attach to a Polestar fiber optic cable. All products are made in the USA.
