Claim:
1. A bioreactor comprising a flexible bag, an optical fiber, an optical sensor, and an attachment arrangement for providing the optical sensor in the flexible bag, said attachment arrangement comprising: a sensor holding part integrated with the flexible bag and comprising first locking means protruding out from the flexible bag, said sensor holding part holding the optical sensor inside the flexible bag; and an adaptor part provided outside the flexible bag and configured to hold the optical fiber, said adaptor part comprising second locking means configured to mate with said first locking means to lock the sensor holding part and the adaptor part together such that the optical fiber can communicate with the optical sensor inside the flexible bag, said adaptor part comprises a surface parallel to a bottom surface of the flexible bag, said surface of said adaptor part configured to receive the optical fiber therein and arranged to hold the optical fiber along the bottom surface of the flexible bag without the optical fiber being in direct contact with the bottom surface of the flexible bag, wherein (i) the optical fiber is parallel to the flexible bag and the optical sensor and (ii) a mirror connected with the surface of the adaptor part is disposed beneath the optical sensor, and configured to form an optical path directly from the optical fiber to the optical sensor and to direct light from the optical fiber onto the optical sensor.
