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.

Single-use connection device

A method for controlling electrical power consumption for a first group of functional which can be used for operational management during operation of the bioreactor components during operation comprises, inter alia, adjusting a present power control signal for one or more of the functional components from the first group in order to optimise power consumption, when a comparison shows for the first group of functional components that the currently required total electrical power consumption is greater than a predefined total electrical power consumption, such that, for the first group of functional components, an adjusted total electrical power consumption is not greater than the predefined total electrical power consumption. A biotechnological apparatus comprises a bioreactor, a reactor vessel formed in the bioreactor and having a cultivation chamber, and a temperature control device provided with a heat pump and configured to control the temperature of the cultivation chamber.

Method for controlled operation of a biotechnological apparatus and bioreactor system

The present invention refers to release matrices which include a material that can be released in a controlled way or with predefined kinetics into a surrounding medium, reaction vessels comprising said release matrices, and release system further comprising a medium which is able to dissolve the embedded material. The present invention further refers to the use of release matrices in several applications and the production method for such matrices. The present invention also relates to a method that al lows control of the release rate of materials from polymer matrices with several factors.

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.

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.
