Abstract: A reactor (100) for electrochemical synthesis is proposed. The reactor (100) comprises a vessel (102) configured to receive a reaction mixture comprising an electrolytic medium and at least one reactant, at least a first electrode (108), and at least a second electrode (110). The first electrode (108) and the second electrode (110) are arranged within the vessel (102) and inter-penetrate one another without electrical contact. The first electrode (108) and/or the second electrode (110) are three dimensionally grid-shaped, the first electrode (108) and the second electrode (110) being arranged so as to allow and/or purposefully direct a flow of the reaction mixture therebetween. Further, a method for carrying out an electrochemical synthesis is pro-posed.

Abstract: The present invention relates to a simulation model for simulating a tube line comprising at least one hollow cylindrical section that is configured to be arranged in a tube receiver of a blood leak detector of a blood treatment machine, wherein a respective receiver for a respective light source is provided at the axial ends of the hollow cylindrical section, by means of which light source light can be introduced into the hollow cylindrical section; and at least one light guidance element that is arranged in the hollow cylindrical section and that is configured to deflect light introduced into the hollow cylindrical section such that the light moves outwardly out of the hollow cylindrical section through at least one opening in a radial outer side of the hollow cylindrical section. The invention further relates to a method of checking the function of a blood leak detector by means of a simulation model in accordance with the invention.
