What is proposed is an emulsifying system with an emulsifying device and an injection nozzle as well as an emulsifying device for producing a water-fuel emulsion for an internal combustion engine, wherein the emulsifying device is embodied as a rotor-stator emulsifying device and/or fluid flow machine and/or is connected or connectable directly to an injection nozzle. The emulsifying device has a housing and a shaft, the shaft being drivable in a contactless manner, the housing having a guide apparatus having a plurality of guide channels for guiding the flow, and/or the housing being made at least partially from fiber composite material.

A method for assembling a mixer-container intended for receiving a biopharmaceutical fluid includes providing a container with a mixing device including at least one shaft having an adjustable length, and at least one first bearing attached to a wall of the container, the shaft extending at least into the inner space from the first bearing; a rigid outer device that compresses the container; and a drive motor located outside the container, the first bearing of the container is placed so as to be spaced apart from the motor, and the length of the shaft is adjusted along the main axis by arranging the shaft opposite the motor to enable the motor to rotate the shaft.

A magnetic coupling assembly for a magnetic stirrer includes a non-magnetic disc embedded with two or more pairs of magnets. The two magnets of each pair are oriented with opposite magnetic poles pointing in the upward direction. When the magnetic coupling assembly is driven to rotate, it can bind one or more axially magnetized stir bar in a mixer at a relatively higher speed to achieve better mixing result without causing spin-out or jumping-flea phenomena, compared to when only one pair of magnets is used.

An agitator comprising a rotatable impeller comprising blades, magnets, and a shaft, wherein the impeller is configured to be driven by a drive unit magnetically coupled to the impeller, and an impeller seat receiving the rotatable impeller, the impeller seat comprising an upwardly arranged cylindrical housing, a flange, and a base, the cylindrical housing comprising a central opening for the impeller shaft, and the base comprising a collar and pins arranged to engage with a locking and centering mechanism, as well as a mixer engagement unit including the agitator, a mixer system, a mixing vessel, and methods of using the agitator, mixer engagement unit, mixer system, and mixing vessel, are disclosed.

The invention relates to an emulsification device for continuously producing emulsions, nano-emulsions, and/or dispersions having a liquid crystalline structure, comprising a) at least one mixing system, b) at least one drive for the stirring element, and c) at least one delivery unit for each component or each component mixture.

A packaging for a flexible container, in particular for a disposable bag for use in a bioreactor, including a bottom part for fixing a first portion of the container, a ceiling part for fixing an opposite second portion of the container, a receiving space which on a first side is defined by the bottom part and on an opposite second side is defined by the ceiling part, and struts arranged between the bottom part and the ceiling part, which fix a defined distance between the bottom part and the ceiling part.

A nano-bubble generator includes: (i) a housing defining: an inlet for receiving a liquid with entrained macro-bubbles: a first chamber operatively downstream of the inlet; a second chamber operatively downstream of the first chamber; and an outlet operatively downstream of the second chamber; (ii) at least one blade disposed within the first chamber for, in use, cutting macro-bubbles entrained in the liquid to convert such macro-bubbles into micro-bubbles; (iii) at least one first magnet within the second chamber; and (iv) at least one second magnet associated with the second chamber, wherein: (a) the at least one first magnet and the at least one second magnet are arranged such that the polarity of the at least one first magnet is opposed to the polarity of the at least one second magnet; and (b) the at least one first magnet is movable relative to the at least one second magnet.
