  • Patent number: 8129174
    Abstract: 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.
