Patent number: 8129174Abstract: A method for separating carriers from a solution, the carriers being adapted to have biomolecules, such as DNA, RNA, proteins, polypeptides or carbohydrates attached thereto. The method includes the steps of introducing a tubular member (13) into a receptacle which holds a solution containing the carriers immersing an end portion of the tubular member in the solution attracting and holding the carriers to the end portion and removing the tubular member together with the held carriers from the solution. The attracting and holding step includes the step of providing an under-pressure within the tubular member so as to attract and hold the carriers to a filter (25) being disposed in the end portion of the tubular member. The invention also relates to an apparatus (10) performing such a method.Type: GrantFiled: February 12, 2003Date of Patent: March 6, 2012Assignee: Qiagen Instruments AGInventors: Anders Alderborn, David Peterson, Bjorn Ingemarsson, Anna-Lotta Schiller

Patent number: 7927495Abstract: A device (10) is described for automatically separating solid and liquid phases of a suspension (78) and for purifying magnetic microparticles (76) loaded with organic, e.g., biological or biochemical substances. The device includes a process area (12) with devices, which move in a cyclic manner for transporting the magnetic microparticles (76) in the x-direction. A first guide (14) is used for supplying sample containers (P) in the x-direction and second guides (18) are used for supplying reagent containers (R) in the y-direction to the process area (12). The second guides (18) in the y-direction extend at an angle (?) of 30 to 150 ° to the x-direction. A carrier element (24), including carrier plates (24a, 24b, 24c) can be moved back and forth in the x-direction and can be lifted and lowered in the z-direction.Type: GrantFiled: January 4, 2005Date of Patent: April 19, 2011Assignee: Qiagen Instruments AGInventor: Konstantin Lutze
