Abstract: A fixed-angle rotor for centrifuges includes stiffening ribs on the lower side of its rotor body. Its rotational energy is comparatively low during operation even at high speeds, whereby safety is noticeably increased without the need for a reinforced armored vessel in the centrifuge that is equipped therewith. At the same time, the drive power required to drive the fixed-angle rotor remains low. The fixed-angle rotor also withstands extreme loads over a long period of time. In addition, the fixed-angle rotor can be manufactured cost-effectively, because no additional components are required; rather, the stiffening ribs can also be manufactured during the manufacture of the rotor body. Finally, very thin rotor shells can also be used, which improves the temperature control of the samples, because the fixed-angle rotor has very good structural stability, especially in the main load directions.

IPC: B04B5/04
Abstract: 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.

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.
