Abstract: A system for providing a sterile fluid connection between a first fluid channel and a second fluid channel. The system includes first and second coupling elements located at an orifice of each the first and second fluid channels, respectively. The first and second coupling element each include a foil that may be peeled off their respective orifices. The system additionally includes a connecting element configured to accommodate the first and second coupling elements and to press the orifices of the first and second fluid channels against one another. Additionally, this connecting element has a recess arranged essentially in the plane of the orifices of the fluid channels for passing the foils through the connecting element.

Abstract: A modular stirrer having a drive unit, a stirrer unit, and a magnetic coupling. The magnetic coupling is arranged between the drive unit and the stirrer unit and has a cylindrical cavity, drive magnets as well as stirrer unit magnets, and the drive magnets are connected to the drive unit and the stirrer unit magnets are connected to the stirrer unit and arranged radially about the cavity. The cavity is open at the opposite end in the opened state of the magnetic coupling, and the drive magnets may be inserted into the cavity of the magnetic coupling for closing the magnetic coupling for coupling of drive unit and stirrer unit and may be arranged in a plane one with the stirrer unit magnets. The magnetic coupling has a quick-release closure, which closes the cavity upon closing the magnetic coupling and creates a connection of drive unit and stirrer unit.

Abstract: A structural element for more rapidly erecting a tiled stove comprises a quadrangular tile and a quadrangular separate element associated to this tile. The tile has a tile leaf, at the inner side of which a tile body is disposed being unitary with the tile leaf. Two adjacent tiles confine a vertical groove, preferably having a dove-tail cross section, which groove is completely filled by a protrusion of the separate element, which protrusion protrudes from the outer side of a plate of the separate element which plate covers substantially the half of the inner surface of two adjacent tiles each.
