In one embodiment, a disposable bioreactor including a headplate and a stirrer. The headplate has at least one inlet port aperture and one outlet port aperture formed therein and is adapted to couple sealingly with a bag capable of receiving a culture medium. The stirrer is coupled to and extends from the headplate and is adapted to stir the culture medium when the headplate is coupled to the bag. The bioreactor is adapted to fit within the upper opening of the stand of an existing conventional glass bioreactor, so that the bag is suspended within the vessel.

A sensor adapter is described for the noninvasive positioning of a sensor, especially of an electrochemical sensor, in a medium. The sensor adapter comprises an accommodating channel, in which the sensor can be positioned and the one end region of which is closed off by a semipermeable membrane. Moreover, the sensor adapter comprises a hollow cylindrical sealing structure, which is disposed within the accommodating channel coaxially with the longitudinal axis of the latter and with which the sensor can be disposed gas tight adjacent to the semipermeable membrane.

A simple, robust and low-cost torsionally flexible, sealed drive that allows external drives to provide agitation within a container. A torsionally flexible tube is sealed to a torsionally rigid portion of a container. A second end of the tube is sealed to a driven element within the container. The driven element is coupled to a drive-shaft that is partly contained within the tube. Motion of the protruding end of the drive shaft imparts a corresponding motion to the driven element, while maintaining a water-tight seal between container and drive-shaft. One useful motion is a rotary oscillation. A stepper motor may operate via such a drive to impart a rotary oscillation to an impellor in a bioreactor, or mixing container, suitable for agitating a cell culture in a nutrient medium or hydrating a powdered media in water. The drive is suited to use in disposable bioreactors and mixers.
