A mixing device having a stirring element can include: a container for receiving fluids and/or solids; and at least one rotatable stirring element for mixing the fluids and/or solids; wherein the stirring element comprises a first bearing element and a second bearing element which are arranged at or near opposite ends of the stirring element; wherein the first bearing element is mounted on a first face of the container and the second bearing element is mounted on an opposite second face of the container; wherein the first bearing element comprises at least one non-permanently magnetized element such that it can be moved in rotation by externally induced reluctance forces, and wherein the second bearing element is mounted in a contactless manner by externally induced magnetic forces.

Mixing device having a stirring element

A container () of a bioreactor (a,) has a container interior () designed for being filled with a medium () including a photoreactive material, and designed for at least partially triggering a photochemical reaction of the photoreactive material. The container () has at least one illuminant receiving pouch () that is at least partially transparent for an electromagnetic radiation (), and that is arranged on a illuminant opening () within the container interior () and is designed to receive at least one illuminant () from an outer side (A) through the illuminant opening (). The illuminant at least partially irradiates the medium () such that the photochemical reaction of the photoreactive material can be triggered by electromagnetic radiation () emitted by the illuminant and the illuminant is isolated in relation to the medium () by the illuminant receiving pouch ().

Illumination for a photobioreactor

A bioreactor () includes a receiving container () for receiving a disposable bag (). A bottom surface () of the receiving container () is designed to support the disposable bag () in the receiving container (). An outlet opening () is formed in the bottom surface () and tapers down with respect to the ground for receiving a drain port () of the disposable bag (). The drain port is complementary to the outlet opening ().

Bioreactor system and method

A probe holder (), for positioning at least one probe () such that the probe () at least partially engages in a system () for biotechnological uses, comprises a holder base () for positioning the probe holder () on the system () for biotechnological uses and at least one probe positioning means (), which is designed to position the at least one probe () such that the probe () extends in a probe extension direction (S; S, S, S, S). The probe positioning means () is positioned on the holder base () such that the position of the probe () is variably adjustable in a probe extension direction (S; S, S, S, S).

Probe holder and method for positioning a probe

The invention relates to a mixing system, in particular a bioreactor and/or a pallet tank, for mixing a fluid and/or solid, having a container (), wherein the fluid and/or the solid and a rotatable stirring element () for mixing the fluid and/or the solid are arranged in the interior of the container (). The mixing system furthermore has a mixing device () for receiving the container () and a drive device () for driving the stirring element (). The drive device () comprises a stator () of a three-phase machine (), the stirring element () comprises a rotor () of the three-phase machine (), and the rotor () has at least one permanent magnet (') and/or at least one short circuit rotor.

Mixing system, mixing device, container, and method for mixing a fluid and/or a solid

A system for receiving a disposable bag () has a receiving container () with a container interior for receiving the disposable bag () and a temperature-control hollow wall () that at least partially surrounds the container interior of the receiving container (). A temperature-control unit controls the temperature of the container interior by will a temperature-control medium arranged in the temperature-control hollow wall () at a maximum pressure of about 1 bar.
