  • Patent number: 8685322
    Abstract: The invention comprises an apparatus 10 and a method 100 for purifying biomolecules 28. Magnetizable particles 35 and a group of magnetizable pins 40 are used for binding biomolecules 28 to the magnetizable particles 35 using a binding buffer 30b, and for transferring the magnetizable particles 35 forming a particle-biomolecule complex 36. The apparatus 10 comprises an incubation unit 60 that allows for an upscaling of a maximum volume of a sample material. Furthermore the apparatus 10 comprises counter magnets 50 which are arranged on cavities 20. Solutions 30 comprising the biomolecules 28 and the magnetizable particles 35 are disposed in the cavities. The use of counter magnets 50 improves the quality of an eluate. Furthermore the invention comprises a system 800 and a method 900 for a diagnostically purifying of biomolecules 28.

  • Patent number: 8454825
    Abstract: A rod assembly for the extraction of magnetizable particles from solutions is described. The rod assembly includes at least one guide element. A rod element is insertable into the at least one guide element and moveable in a direction substantially parallel to the at least one guide element. A magnet element is moveable to a distal magnet element position; wherein the distal magnet element position is located on a distal end section of the at least one guide element; wherein the at least one guide element includes an opening at a distal end. A method for the extraction of magnetizable particles from solutions is also described, as well as a magnet element for the extraction of magnetizable particles from solutions.

  • Publication number: 20090176308
    Abstract: The invention comprises an apparatus 10 and a method 100 for automatically lysing, extracting and purifying biomolecules 28. As the central technology for purifying the biomolecules magnetizable particles 35 and an adapted magnet device 40 are used for binding and transferring the particles 35. The apparatus 10 comprises a highly efficient incubation unit 60 with options for upscaling the maximum sample amount. Furthermore the apparatus 10 in particular comprises a group of magnetizable pins 40 as transport magnets and furthermore counter magnets 50 which are arranged on the cavities 20, in which solutions 30 with the biomolecules 28 to be lysed and magnetizable particles 35 are disposed. The use of counter magnets 50 improves the quality of the eluate. Furthermore the invention comprises a fully automatic system 800 and a method 100 for controlling the process steps and the selection of the reagents and the aids (e.g.
