A device for the mixing fluid media. The device is a bladeless mixer. The device comprises a hollow body with at least a single inlet opening in its bottom and at least a single outflow region in its side. The device is rotated at a speed at which the media due to centrifugal forces enters the device's hollow cavity via the inflow opening or unit. The media is discharged from the cavity through one or more outlet units or openings in the sides or in the top of the device. During mixing the media does not rise above the level of the undisturbed media.

An enzymatic processing plant for continuous flow-based enzymatic processing of organic molecules, comprises an enzymatic processing area, wherein the enzymatic processing area comprises a turbulence-generating pipe with a repeatedly changing centre-line and/or a repeatedly changing cross-section, for generating turbulence to mix a reaction mixture and prevent sedimentation of particles as the reaction mixture is flowing through the turbulence-generating pipe, and wherein the enzymatic processing plant and the enzymatic processing area are arranged such that the reaction mixture is subjected to turbulence within the enzymatic processing area for a reaction time of 15 minutes or more.

A microfluidic device and method is provided for concentrating particles in a fluid sample. The microfluidic device has a chamber, wherein the chamber has a filtering unit defining a first compartment and a second compartment, the first compartment being in fluid communication with the second compartment and being for receiving a fluid sample containing particles, the filtering unit being configured to selectively retain particles of the fluid sample based on a size of the particles, at a sub-region of the first compartment as the fluid sample flows from the first compartment to the second compartment; and an acoustic transducer configured to generate acoustic waves in the sub-region to disperse the particles.

A disposable container, such as a deformable bag, for a fluid, having one or more inlets and one or more outlets and an impeller assembly within the container to cause mixing, dispersing, homogenizing and/or circulation of one or more ingredients contained or added to the container. The region within the container that can contain liquid is funnel shaped, which allows very low fluid level mixing, dispensing while mixing, and a reduction or elimination of vortex formation.

A bioreactor apparatus includes a vessel establishing an interior space environmentally separable from an exterior space outside of the vessel, an agitation system including mixing means arranged in the interior space and drive means adapted to rotate the mixing means. The drive means includes a drive motor that is arranged in the interior space.

A mixing system and mixing method are provided. The mixing system includes a tank assembly, a container positioned within the tank assembly, a mixer disposed within a compartment of the container, a linear motor, and a shaft having a first end secured to the mixer and an opposing second end secured to the linear motor. The linear motor provides a variable stroke length for the shaft. The mixing method includes providing a tank assembly having a linear motor, positioning a mixing assembly including a mixing bag in the tank assembly, combining two or more components in a compartment of the mixing bag, attaching a mixing shaft extending from a mixer disposed within the mixing bag to the linear motor, and raising and lowering the mixing shaft to mix the two or more components. A stroke length of the mixing shaft during the raising and lowering is varied.

A system for oxygenating a biological culture includes a container bounding a compartment and having a top wall, a bottom wall, and an encircling sidewall extending therebetween; a tubular member projecting into the compartment of the container and terminating at a terminal end; a gas supply coupled with the tubular member and being configured to blow gas through the tubular member; and a mixing element disposed within compartment of the container at a location between the terminal end of the tubular member and the bottom wall of the container, the mixing element being configured to mix the liquid.

The insert shelf (1) is characterized in that it has at least one means (3) with which an incubation medium located in an incubation vessel placed on the insert shelf (1) can be set in motion during an incubation treatment or during an incubation process in an incubator (2). For this purpose, the at least one means (3) can be operated electrically and/or preferably moved mechanically.

A cylindrical flow distributor (100) for performing, by means of solid reaction members, a biological or chemical transformation, or physical or chemical trapping from, or release of agents to, a fluidic media is provided. The flow distributor (100) comprises: a top wall (1); a bottom wall (2) comprising a central through going opening (13); and an outer wall (3) extending between the top wall (1) and the bottom wall (2). The top wall (1), the bottom wall (2) and an inner envelope surface (5) of said outer wall (3) together define a confinement (7) configured to contain solid reaction membersor a rigid body of a reaction member material. The outer wall (3) comprises a first plurality of longitudinally extending ribs (20) arranged side by side with longitudinal gaps (21) extending in the circumferential direction between two adjacent ribs (20), and a circumferentially extending first scaffold (22) encircling and being fixedly attached to a peripheral outer surface (29) of said plurality of longitudinally extending ribs (20). Further, a reactor using such flow distributor (100) is provided.

The invention relates to a method and to a device for feeding gases or gas mixtures into a liquid, suspension, or emulsion in a reactor in a specific manner. According to the invention, gases or gas mixtures are fed into a liquid, suspension, or emulsion in a reactor in a specific manner, wherein the gas or gas mixture is fed in a specific amount and/or at defined points in time in one pulse as a gas bubble into a flowing liquid in a tilted reactor system, whereby a pulsation effect is obtained, wherein a driving force is produced by means of an adiabatic relaxation of the fed-in gas or gas mixture, by means of which driving force wall adhesions on the reactor are prevented.
