A centrifuge includes a swing rotor. Rotor arms of the swing rotor have recesses into which hangers of the swing rotor at least partially swing in a swung-out state. As a result, the centrifuge container and thus also the centrifuges are more compact, because the swinging-out requires less space. An inertial mass of the swing rotor is reduced due to the recesses provided therein, whereby energy consumption, primarily when starting the centrifuge, is significantly reduced.

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.

The present invention relates to a lid for closing a centrifuge rotor, characterized by a form-fitting, rotation-actuated closure mechanism which, pre-positioned on the centrifuge rotor, moves automatically into a closed position by virtue of the intrinsic weight of the lid.

A laboratory device for jointly tempering reaction samples in at least two steps in respectively assigned, specified temperature ranges, which are carried out repeatedly and consecutively as sequences of steps, the laboratory tempering device, in one step of the sequences of steps, bringing several groups of samples, in each case containing at least one sample, to temperatures within the temperature range, which are constant within the groups and different between the groups, wherein the laboratory tempering device, in each step of the sequence, brings a different partial amount of the samples in groups to temperatures, which are the same within the groups and different between the groups, and brings the samples of the other partial amounts to a same temperature within the assigned temperature range.
