Publication number: 20070110629Abstract: The invention relates to a sampling device (1) for a microreaction system (3), comprising an outlet (4) and a suction line opening (9) which is arranged next to the outlet (4). A depression can be produced in the suction line (9) for the suction of the substances (13) leaving the outlet (4). The outlet (4) is embodied as a capillary and can be positioned in relation to the opening of the suction line (9). The outlet (4) is surrounded by a housing (6) comprising a discharge outlet (14) for the substances (13) leaving the outlet (4), and a through-opening (8) for the suction line (9). Said suction line (9) opens up into a collecting tank (10) that is connected to a vacuum line (12) by means of an electrovalve (1).Type: ApplicationFiled: June 5, 2004Publication date: May 17, 2007Inventors: Michael Schmelz, Gunter Brenner, Thomas Greve, Hanns Wurziger, Mirco Arndt

Patent number: 7001576Abstract: 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).Type: GrantFiled: May 9, 2001Date of Patent: February 21, 2006Assignee: Merck Patent GmbHInventors: Michael Hohmann, Michael Schmelz, Günter Brenner, Hanns Wurziger, Norbert Schwesinger

Publication number: 20050158209Abstract: A microcomponent connection system (1) having an accomodation device for plate-shaped microcomponents (7) has a connection block (2) and a lifting device (6), by means of which the microcomponent (7) and the connection block (2) can be pressed against one another. The connection block (2) has electrical and fluid line connections (8, 9) and optical line connections (16), each of which projects in a sprung or spring-mounted manner on the underside of the connection block (2). In order to connect the microcomponent (7) to the associated line connections (8, 9, 16), the microcomponent (7) is pressed by the lifting device (6) in the direction of the connection block (2) against the electrical line connections (8) or fluid line connections (9) designed as electrically conducting spring tongues or as hollow rams (10), or optical line connections (16).Type: ApplicationFiled: February 10, 2003Publication date: July 21, 2005Applicant: Merck Patent GmbHInventors: Renate Bender, Gunter Brenner, Thomas Greve, Matthias Joehnck, Bernd Stanislawski, Michael Schmelz, Sigrid Sturmfels
