Patent number: 9121057Abstract: A method of filling a cartridge that includes a reaction chamber, a biochip mounted in the reaction chamber and a compensation chamber connected so as to communicate with the reaction chamber. The method includes placing a filling nozzle, which is connected so as to communicate with the reaction chamber, such that it is facing upwards, filling a liquid biological sample into the filling nozzle, pressing a stopper into the filling nozzle in order to force sample liquid into the reaction chamber, so that the reaction chamber is filled from bottom to top and an air bubble remains in the compensation chamber downstream of the reaction chamber.Type: GrantFiled: May 21, 2013Date of Patent: September 1, 2015Assignee: ZENTERIS GMBHInventors: Jens Göhring, Stefan Heydenhauss, Friedrich Menges, Reiner Spolaczyk, Jana Lepschi

Patent number: 8926922Abstract: The invention relates to a heated reaction chamber for processing a biochip and to a method for controlling said reaction chamber. The heated reaction chamber for processing a biochip comprises a chamber wall, constituted by a flexible circuit board (10), a circuit path (10.3) being configured on the flexible circuit board (10) and being used as the heating device. The use of a flexible circuit board as the wall of a reaction chamber allows for a low thermal capacity of the reaction chamber in the area of the heating device, thereby allowing the chamber to be heated up quickly.Type: GrantFiled: December 28, 2011Date of Patent: January 6, 2015Assignee: Zenteris GmbHInventors: Jana Lepschi, Jens Gohring, Stefan Heydenhaus, Manuel Ullrich

Patent number: 8151589Abstract: The invention relates to a cooling device for a reaction chamber for processing a biochip and to a method for controlling said cooling device. The cooling device (50) according to the invention comprises a cooling piston (51), a cooling unit (52) for cooling the cooling piston (51) and a drive (53) for displacing the cooling piston (51) or the reaction chamber in such a manner that the cooling piston can be brought into contact with a wall of the reaction chamber (5) and can be removed again. The cooling device (50) according to the invention allows high cooling rates and a high reproducibility of cooling processes. It has a simple design and can be reliably used in portable devices for examining biochips.Type: GrantFiled: June 27, 2007Date of Patent: April 10, 2012Assignee: Zenteris, GmbHInventors: Jana Lepschi, Jens Gohring, Stefan Heydenhaus, Manuel Ullrich

Publication number: 20100068822Abstract: The invention relates to a device for carrying out tests on and analyzing biological samples with temperature-controlled biological reactions. It comprises: A reaction chamber (5) for receiving a biochip (6). The reaction chamber comprises at least one transparent window (14) so that excitation light from outside can be radiated onto the biochip (6) and fluorescence light from the biochip can be radiated outward towards a measuring device. A membrane which forms at least one wall of the reaction chamber and is formed so as to be elastic so that the window and the biochip can be pressed against each other to displace the sample solution arranged thereinbetween. The device of the invention is distinguished in that the reaction chamber communicates with a compensation chamber.Type: ApplicationFiled: November 27, 2007Publication date: March 18, 2010Applicant: ZENTERIS GMBHInventors: Stefan Heydenhauss, Jens Göhring, Friedrich Menges, Jürgen Bauer
