Abstract: Device for mounting flexible, profiled hollow cylinders onto cylindrical elements. Profiled hollow cylinders which are mounted onto a cylindrical element form excellent modules for irradiating fluid media with electromagnetic radiation.

Abstract: Method for transport of suspensions containing mechanically sensitive material with a sample-transporting device comprising transport conduits and at least one system for accelerating a sample or aliquot through the transport conduit from at least two burets.

Abstract: The invention relates to a reactor driven in an oscillatory-rotary manner about its fixed, preferably vertical, axis, for preferably biotechnological and pharmaceutical applications. By means of its process-intensifying properties for mixing, suspension, gaseous material transport, heat transfer, irradiation and particle retention, the applicability on the industrial scale is ensured. The reactor which succeeds without a shaft seal permits particularly robust production with respect to sterile technique with avoidance of cleaning and cleaning validation required when the reactor is constructed as a single-use reactor.

Abstract: Sampling valve with which samples containing mechanically sensitive material are removed in a sterile manner from a bioreactor, and process analysis system with analysis stations, in particular chromatography systems, biosensors and cell determination devices, permitting automated, sterile removal of a sample from a bioreactor and gentle transport of the sample, containing mechanically sensitive material, in particular cells, to the analysis station.

Abstract: Described is a reactor for irradiating ultraviolet light into a fluid reaction medium (3). The reactor consists of at least one housing (15) which encloses a tubular cavity, with a radiation source (1) for generating ultraviolet light and an inner tube (2) which, together with the housing (15), forms an irradiation chamber (26) which, in particular, is of annular shape, the irradiation chamber (26) being connected at least with an inlet (13) and an outlet (14) for the reaction medium (3) and is perfused by reaction medium (3) in the longitudinal direction of the tube (2), the irradiation chamber (26) being equipped with means (6, 25) for generating an additional radial flow routing of the reaction medium (3).

Abstract: The fluid-bed reactor for biological effluent treatment, using carrier particles for microorganisms, consists of a tank with a retention system for the carrier particles, gas supply units and a jet ejector arranged along the tank for the particle recycle. The propulsion nozzle of the jet ejector is fed with the effluent stream which is to be treated.

Abstract: The fluidized bed reactor for biological treatment of effluent essentially comprises a container (1) over the base 2 of which elongated gassing units having gas exit apertures (5) are arranged parallel to one another, in such a way that in each case two neighboring circulating currents (8, 9) in mirror-image symmetry are produced in the reactor. In addition, the reactor (1) is supplied with a retention system (16) arranged on the outside for the separation of carrier particles for biocatalysts suspended in the effluent.
