Abstract

A sensor device has an optical sensor (1), a container (2) and a compartmentalizer (3) that temporarily divides the container into a main space (4) and an adjacent space (5), in which the optical sensor (1) is located. The gas volume in the direct vicinity of the optical sensor (1) is reduced, as are also, consequently, the reactive products generated by radiation sterilization. The adjacent space (5) can be united with the main space (4) after the sterilization as a result of the temporary compartmentalization. The optical sensor is suitable for implementation in containers and laboratory products, such as, for example, disposable bioreactors, that are sterilized by gamma radiation.
