摘要:
A mixing system has a single-use container (1) with flexible walls and a mixing device. The mixing device has at least one encapsulated drive (5) and a mixer shaft (3). The drive (5) can be disposed of after use together with the mixer shaft (3) and the single-use container (1). The mixing system can be used in biotechnology and the pharmaceutical industry for mixing liquids, dissolving solids or cultivating cells and microorganisms.

摘要:
A mixing system has a container with flexible walls (1), a fluid-tight drive space (6) and a mixing device. The container with flexible walls (1) has at least one head plate (5). The fluid-tight drive space (6) is outside of the container interior (2), and is enclosed by the head plate (5) and a cap (7) attached to the head plate (5). The mixing device has a stirrer shaft (3), onto which stirrer elements (4, 4′) are attached. The stirrer shaft (3) is guided from the container interior (2) through an opening in the head plate (5) and the section of the stirrer shaft (3) in the drive space (6) is guided by bearings (9, 10). A seal (8) is fit into the opening of the head plate, and encloses the stirrer shaft (3) and seals the container interior (2) from the drive space (6).

摘要:
A bioreactor (1) having a container (2), a shaft housing (3) for guiding a shaft (5) through a wall (7), a stirrer (6) connected to the shaft (5) in the interior (9) of the container (2), and a drive (4) arranged outside the container (2) and connectable to the shaft (5). The shaft (5) is mounted in the shaft housing (3) via at least one ball bearing (23) and is sealed in relation to the shaft housing (3) by at least one seal (11, 20). The seal (11, 20) is configured as a radial shaft seal (28) having two sealing lips (30, 31) that are arranged one behind the other in the longitudinal direction of the shaft (5) and are able to run on the shaft (5) without lubricant.

摘要:
Container system with one container (1) with a flexible partition, in particular a disposable container, that can be inserted into a carrying container that supports its lateral container partition (10) and in which liquid medium (8) that has been poured in can be mixed, with the carrying container (4) featuring at least one baffle (15, 15′, 15″, 15′″) on the internal support partition (11) that forms the lateral container partition.
摘要:
A vibrational mixer (1), in particular a single-path mixer for use in single-path bioreactors (4) with flexible walls, consisting of a mixer shaft (2) that can be set into longitudinal motions by a drive (8), with at least one mixing element (3), wherein at least one channel (13) is arranged in the mixer shaft with an opening to an interior reactor space (6).
摘要:
A stirrer for a bioreactor has first and second opposed mountings fastened to the inner surfaces of opposite walls of the bioreactor and disposed along a common rotational axis. A first arm has an end connected to the first mounting for rotation about the rotational axis and for pivoting about a first pivot axis that is transverse to the rotational axis. A second arm has an end connected to the second mounting for rotation about the rotational axis and for pivoting about a second pivot axis that is transverse to the rotational axis. Ends of the arms are coupled for pivoting about at least one additional pivot axis that is transverse to the rotational axis.
摘要:
A container has flexible walls defining an interior. A mixer is arranged in the interior of the container and includes a mixer shaft with opposite first and second ends. A mixing element is mounted to the first end of the mixer shaft. The second end of the mixer shaft is fixed magnetically to a coupling piece disposed on the exterior of the flexible wall of the container. The coupling piece is connected operatively to a force introducing device that generates movement of the mixer.
