A single-use biobag provided with at least two none invasive florescent-optical sensors. The sterile sensors inside the biobag secured by an adhesive backing or secured by a CLASS VI fitting assures the sterile environment of the fluids in the bags. The sensors detectors are located outside the bag and secured in a position to align the sensors with the detectors. Either Velcro on the detector and outside of the bag has been used for sensor/detector alignment or the detector is mounted on the containment vessel and biobag straps are used to assure position of the bag for sensor/detector alignment. The process variables to be measured by the fluorescent optical disposable sensors are: DO, pH, CO<SUB>2 </SUB>and temperature. The biobag film is CLASS VI material and should be optically clear and free of interfering florescent compounds.
