Abstract: A device for the emulsification and separation of small amounts of immiscible liquid phases has essentially a cover plate (2), which can be tightly connected to a base plate (1), where microchannels (4,4a,5,6,6a) in the form of grooves are cut out on the inner surface (3,3a) of the base plate (1) and/or cover plate (2). In a mixing zone, two microchannels (4,4a) run in a wave shape crossing one another a number of times. In a subsequent separation zone, they run essentially straight combined in a common microchannel (5). The otherwise tightly sealed-off microchannels (4,4a,5,6,6a) can be filled and emptied again via inlet apertures (8,8a) and outlet apertures (9,9a).

Abstract: A device for carrying out the parallel incubation of solutions comprises a holding frame (1) inside of which one or more titer plates (2) can be placed. Each titer plate (2) is separately closed by a cover plate (4), which can be pressed thereon, resulting in the prevention of unwanted evaporation effects and transport phenomena. Seals (5) are placed between the cover plate (4) and the holding frame (1). Continuous recesses in the holding frame (1) are located underneath the titer plates (2) and are occluded by a common one-piece bottom plate (7) having punch-like protrusions (6). Devices for regulating temperature can be arranged both inside the cover plate (4), the holding frame (1) as well as inside the one-piece bottom plate (7). The holding frame (1) comprises channel-like recesses for accommodating liquid solvent.

Abstract: A connection coupling forms a line connection for liquid or gaseous substances to microcomponents (1) in platelet form. A coupling body (2), which is substantially U-shaped in cross section, accommodates the edge of the plate-like microcomponent (1) between an upper limb plate (3), which has the line connection (14), and a lower limb plate (5). An edge web (6) forms a transverse stop for an edge (8) of the microcomponent (1). A further stop means, for example a lug (9), forms a longitudinal stop for positioning of the microcomponents (1).

Abstract: Compounds of the formula I wherein R1, R2 and R3 have the meanings defined herein, and also their physiologically acceptable salts, inhibit the binding of fibrinogen to the corresponding receptor and can be employed for the treatment of thromboses, osteoporoses, oncoses, apoplexy, cardiac infarct, ischaemias, inflammations, arteriosclerosis and osteolytic disorders.

Abstract: Microwells, which are open on both sides and are arranged two-dimensionally in a microwell matrix (4), are hermetically closed by pressure on both sides using plugs (6) covered with a sealing sheet (11). A layer of elastic material (9), which is arranged between the plug (6) and the sealing sheet (11), guarantees uniform pressure on all the microwells of a microwell matrix (4) which is loosely held by a frame structure (1). Continuous peripheral elevations (2), which protrude in both directions at right angles to the plane of the microwell matrix (4), ensure that the deformable thin layer of elastic material (9) does not escape sideways between the plug (6) and the microwell matrix (4) during the pressing process. A plurality of microwell matrices (4) are held simultaneously by the frame structure (1) and are hermetically closed by a corresponding number of allocated plugs (6), which are fastened to a base plate (7) and a cover plate (8), respectively.
