Patent number: 8658042Abstract: Relates to a microplate carrier (1) for a microplate (2), in whose wells (3) magnetic particles (5), which are suspended in a liquid (4), with or without samples adhering thereto are located, the microplate carrier (1) comprising permanent magnets (6) generating magnetic fields which are implemented to collect and retain the magnetic particles (5) on the floor (14) and/or on the walls (7) of the wells (3) of this microplate (2). The microplate carrier (1) according to the invention is characterized in that it comprises two permanent magnets (6) situated diametrically opposite in relation to the well (3) for each well (3) of the microplate (2), which have the same polarity directed toward the well (3) and whose magnetic axis (25) is at least essentially perpendicular to the footprint of the microplate (2) to be placed. A corresponding method based on the use of the microplate carrier (1) is also disclosed.Type: GrantFiled: August 26, 2008Date of Patent: February 25, 2014Assignee: Tecan Trading AGInventors: Gerhard Fasching, Teresa Hruschka, Lutz Niggl, Patrick Niklaus

Patent number: 7202945Abstract: The present invention relates to a device (1) and a method for determining parameters of fluid-containing samples (2) in a system (3) for individually irradiating the samples (2) with light (4) of a light source (5) in an essentially vertical irradiation direction (6). In this case, this system (3) includes a detector (7) for measuring the light (8) coming from a single sample, and this detector (7) has a detection direction (9?), which lies on an optical axis (9) that is essentially parallel to the optical axis (6) of the light source (5). This device (1) includes at least one reflective surface (10), using which the light (4) coming essentially vertically out of the light source (5) may be at least partially deflected in an essentially horizontal irradiation direction (11).Type: GrantFiled: June 28, 2004Date of Patent: April 10, 2007Assignee: Tecan Trading AGInventors: Andreas Erlbacher, Lutz Niggl, Alois Krutzenbichler

Patent number: 7088054Abstract: An apparatus with a flash lamp can trigger a flash of light by application of an ignition pulse. The apparatus encompasses a first capacitor, a second capacitor, a switching element and a control circuit. The first capacitor, second capacitor and switching element are arranged in a network in such a way that the switching element is located on the low side of a power circuit. The apparatus can be operated in a first mode and a second mode by actuating the control circuit. In the first mode the first capacitor is discharged by the flash lamp, triggering a flash of light of high energy. In the second mode the second capacitor is discharged by the flash lamp and a flash of light of low energy is triggered.Type: GrantFiled: April 27, 2004Date of Patent: August 8, 2006Assignee: Tecan Trading AGInventors: Andreas Erlbacher, Wolfgang Fuchs, Lutz Niggl
