The invention relates to a phage culturing device comprising a fluid line system, which fluid line system is sealed off from the external surroundings and has: an input port (1) to which a sample vessel (4) is or at least can be connected, in particular such that phages, from a sample (5) that is or can be placed in the sample vessel, can be transferred via the input port (1) into the fluid line system; an output port (28) to which a removal vessel (27) is or at least can be detachably fastened, in particular such that phages, preferably phages from the transferred phages and multiplied by culturing, can be removed from the fluid line system via the output port; a filtration device (15) which is arranged in a fluid line between the input port and the output port (28) and has a filter membrane (19) that is permeable to phages towards the output port (28) and is impermeable to bacteria; at least one culture medium reservoir (3) comprising a culture medium; at least one host-bacteria reservoir (6) which in particular is sealed before use, comprises host bacteria and can be connected to the at least one culture medium reservoir (3) by an openable connection line, in particular the host bacteria thereof being in a freeze-dried viable form; wherein the at least one culture medium reservoir (3) is arranged in the fluid line system upstream of the filtration device (15), when viewed in the flow direction from the input port (1) to the output port, in particular such that, upstream of the filtration device (15), in the at least one culture medium reservoir (3), phages transferred into the fluid line system can be multiplied using the host bacteria at least once, preferably multiple times, by means of culturing. The invention relates to a method for preparing phages and a tangential flow filtration device (15).
The invention relates to a single-use housing for enclosing cells and/or co-cultures for in vitro tests, having a plurality of chambers (5) separated from one another which each have at least one inlet opening (10) and one outlet opening (11) for a culture medium and/or treatment medium, wherein the housing (1) is formed from a first housing part (2) and a second housing part (3), and a carrier layer (4) that is permeable to the culture medium and/or treatment medium is secured in the chambers (5) in the first housing part (2), as a result of which carrier layer a first inner lumen (6) and a second inner lumen (7) are formed in the chambers (5).

C12M 3/00 - Appareillage pour la culture de tissus, de cellules humaines, animales ou végétales, ou de virus
The invention relates to a method for transporting plants (1), at least one plant (1) being placed in a transport container (3) filled with water (2) and being transported together with the transport container (3). Prior to transport, a preferably not water-soluble product (5), in particular a first product (5), which floats on the water surface (4), is applied in the liquid state to the water surface (4) in the transport container (3) and the product (5) solidifies.

METHOD FOR ACTIVE CONTROL OF FREQUENCY AND VOLTAGE IN A POWER SUPPLY GRID WITH DECENTRALIZED POWER SUPPLY SYSTEMS
The invention relates to a method for actively controlling in a feedback control at least one output parameter (fi, Vi, Pi, Qi) of a decentralized power generating unit (1) feeding power into a power supply grid (14) having a plurality of such decentralized power generating units, the power generating unit (1) being coupled to the grid (14) at a grid tied point (16). The actual resistance (Ri), reactance (Xi) and magnitude (|Zi|) of the impedance (Ζi) of the power generating unit (1) at the tied point (16) is determined and a first quotient (Ri/|Zi|) between the resistance (Ri) and impedance magnitude (|Zi|) and a second quotient (Χii/|Ζi|) between the reactance (Xi) and the impedance magnitude (|Zi|) is calculated. These quotients (Ri/|Zi|, Xi/|Zi|) are used for the feedback control of the at least one output parameter (fi, Vi, Pi, Qi).
The present invention relates to a sowing heart monitoring device for connection to a sowing heart (3') and for monitoring the sowing heart (3'), having a line scan camera (21) with a detection device (E), a housing (20) which can be fastened to the sowing heart (3') and is intended to accommodate the line scan camera (21), and a radiation source (22) for generating electromagnetic waves which can be detected by the line scan camera (21) and have a radiation direction (S), wherein the sowing heart monitoring device (12) is designed in such a manner that electromagnetic waves generated by the radiation source (22) can be detected by the line scan camera (21) after reflection at a reflection surface (13) of a rotatable sowing disc (9) of the sowing heart (3') and can be evaluated by an evaluation unit. The present invention also relates to a sowing heart and to a single grain sowing machine.
