Abstract: The invention relates to a single-use connection device for insertion into a connection opening of a bioreactor, in particular in a connection opening of a top plate of a dimensionally-stable bioreactor or in a connection opening of a connection element of a pouch bioreactor. The single-use connection device is inserted in a connection opening of a top plate of a bioreactor and/or in a connection opening of a pouch reactor and is provided with multiple passages and an attachment section, wherein the single-use connection device is formed as a single piece and is made of plastic. The attachment section, on an outer peripheral surface, has an attachment structure for attaching the single-use connection device in the connection opening.

Abstract: This patent document relates to the field of biotechnological apparatuses. It relates particularly to a biotechnological apparatus comprising a bioreactor, an exhaust gas temperature control device and a method for treating an exhaust gas stream. This patent document further relates to a connection device for a sterile single-use fluid conduit of a single-use bioreactor and to a method for treating a fluid stream. The reusable connection device comprises a receptacle in which a portion of the fluid conduit can be detachably arranged, and a coupling member connecting the connection device to a temperature control device, the receptacle having a contact surface which is arranged such that the contact surface abuts a fluid conduit arranged in the receptacle, and wherein a portion of a fluid conduit can be introduced into the receptacle in a direction running substantially orthogonally to a longitudinal axis of the connection device.

Abstract: Cuvette, comprising at least one measuring area on each one of two arms that are pivotally connected to each other such that from a swung-apart condition, they can be swung together into a measuring position in which the two measuring areas have a distance for positioning a sample between the measuring areas, and means for positioning the two arms in a measuring position in a cuvette shaft of an optical measuring device with a sample between the two measuring areas in a beam path of the optical measuring device that crosses the cuvette shaft.

Abstract: A single-use bioreactor, suitable in particular for use in a parallel bioreactor system for applications in cell culture and/or microbiology, a head plate for such a single-use bioreactor and a process for manufacturing the single-use bioreactor and the head plate. The single-use bioreactor comprises a head plate, a dimensionally stable container and a mixer, the head plate and the container enclosing a reaction chamber, and the mixer having a mixer shaft and a stirring member, said mixer shaft being mounted rotatably about a rotational axis in a bearing and the stirring member being fastened torsionally rigidly to the mixer shaft. The mixer and the bearing are arranged entirely within the reaction chamber and the mixer shaft has a magnetic portion which is arranged and adapted in such a way that it can be coupled magnetically in an axial direction to a rotary drive.

Abstract: 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.
