摘要： A mixing apparatus for mixing or stirring substances includes a mixing tank for receiving the substances, a rotor arranged in the mixing tank with which a vane for mixing or stirring the substances can be driven to rotate about an axial direction, and a stator arranged outside the mixing tank and with which the rotor can be driven contactlessly magnetically to rotate about the axial direction in the operating state and is supported magnetically with respect to the stator. A bar extends in the axial direction and is rotationally fixed to the rotor, and a limiting element fixed with respect to the mixing tank cooperates with the bar, with the limiting element being configured such that the bar rotates with respect to the limiting element and with a tilt of the rotor being limited by a physical contact between the bar and the limiting element.

摘要： 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.

摘要： 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.
