Abstract
An optical sensor is disclosed for use in an interactive cell processing system that includes a plurality of sensors arranged for monitoring and providing sensor data to a control module that directs processing of biological cells. The sensors including an optical sensor for characterizing a fluid transferred in a sterile manner during the processing. The optical sensor includes a light source, a light detector, a cuvette and a control circuit. The light source is connected to a control circuit and is constructed and arranged to emit light of at least one selected wavelength directed toward the fluid. The cuvette is constructed as a part of a fluid distribution manifold that includes several conduits for transferring the sterile fluid during the processing, wherein the cuvette is constructed and arranged to convey the fluid. The light detector is connected to the control circuit and is constructed and arranged to detect light that was emitted from the source and has interacted with the fluid flowing inside the cuvette. The control circuit is constructed and arranged to characterize the fluid in the cuvette based on the detected light.
