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 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.

A mixing vessel includes a flexible container, elements for mixing its contents, aeration elements, a drain/lower bearing port having a rigid flange provided with a drain passage, attached in a tight manner to the lower portion of the container wall, supporting a lower bearing that is adjacent to the drain passage. The vessel includes an extended element for dispensing aeration gas and is spaced essentially radially from the drain/bearing port; at least one tubular element for dispensing aeration gas extends from the extended dispensing element, in the inside space, along the inside surface of the lower portion and the side portion of the wall of the container and extends on the outside of the container from the upper portion; at least one mixing element is spaced essentially from the lower portion of the container wall, from the lower bearing, and from at least one extended element for dispensing aeration gas.
摘要:
A sensor device has an optical sensor (1), a container (2) and a compartmentalizer (3) that temporarily divides the container into a main space (4) and an adjacent space (5), in which the optical sensor (1) is located. The gas volume in the direct vicinity of the optical sensor (1) is reduced, as are also, consequently, the reactive products generated by radiation sterilization. The adjacent space (5) can be united with the main space (4) after the sterilization as a result of the temporary compartmentalization. The optical sensor is suitable for implementation in containers and laboratory products, such as, for example, disposable bioreactors, that are sterilized by gamma radiation.
摘要:
A method of mixing including providing a flexible container which comprises at least two components, assembling the components from outside the flexible container to form a centrally disposed magnetic driven shaft with at least one impeller, whereby the integrity of the flexible container is maintained, filling the flexible container having the centrally disposed magnetic driven shaft with one or more ingredients of the contents to be mixed; engaging a magnetic element of the centrally disposed magnetic driven shaft with an external magnetic drive element; analyzing the contents of the flexible container using at least one sensor or a sampling line on the flexible container; and draining the contents of the flexible container through a drain port at the bottom of the flexible container.
摘要:
Aeration device for bioreactors with a first aeration element with gas outlet openings of a first size and with at least one second aeration element with gas outlet openings of a second size, the aeration elements being formed by a common housing with separate aeration channels.
