摘要:
The invention discloses an apparatus for removing samples or introducing fluids from/into system(s) having flexible walls. A sampler/fluid dispenser (3) is fixed on the outside with a connecting area (4) of its base (5) on a sample removal region/fluid dispensing region (6) of the flexible wall (2) and, in its interior, has a severing element (8). At least the severing element (8) can be pushed forward in the direction of the sample removal region/fluid dispensing region (6) in order to remove the samples and in order to introduce fluids, in such a way that the wall (2) can be perforated within the sample removal region/fluid dispensing region (6). The system (1) comprises containers, bags or tubes for filling, mixing, transporting, storage of media, such as biological liquids, sera, buffers, ultra-pure water and can be used as biological reactors or cell culture vessels in the pharmaceutical and biotechnical industry.

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 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:
The invention relates to a filtration system and method for carrying out a process for the filtration of fluids, comprising at least one filtration device with at least one filtration element comprising readable data and a check and/or test apparatus to which the filtration device may be connected, by means of data and testing means lines. The check and/or testing device is connected to a process controller, by data exchange means, for regulation and control of the filtration process and the process controller is connected to a filtration databank, by means of data exchange means, which comprises data sets for at least one filter element and/or for each filtration device and/or for the filtration process. The invention further relates to a computer programme product for carrying out a filtration process on fluids whereby programme components may be called up from a programme memory which support the carrying out of the filtration process.

摘要:
A hose system has a pump hose with a hose portion insertable into a pump head of a hose pump. The hose portion has at least a first stop element fixing the hose portion in the feed direction. The first stop element can subsequently be connected immovably to the pump hose at a predefinable position of the pump hose. Thus, the pump hose can be used more universally and can be adapted to different pump heads.
