Abstract
An apparatus for separating magnetic particles from a liquid which contains said particles, said liquid being contained in an elongated vessel () having a length axis (), said vessel being arranged in a vessel holder () with its length axis () in a substantially vertical position, said vessel () having a bottom and a tapered cross-section that diminishes towards the bottom of the vessel and a side wall () which has an outer surface which forms an angle with the length axis () of said vessel (). This apparatus comprises a magnet () having a plane outer surface () and being adapted for being moved by transport means () along a motion path (), said magnet () and said transport means () being so arranged with respect to said vessel () that over a portion of said motion path () said plane outer surface () of said magnet is in contact with a portion of said outer surface of said side wall () of said vessel (), and transport means () for moving said magnet () between a first predetermined position and a second predetermined position along said motion path ().
