Claim 19:
20. A method for washing magnetic beads in a reaction vessel unit with a centrifuge, wherein the centrifuge comprises a rotor with a horizontal rotation axis, the reaction vessel unit comprises a plurality of reaction vessels, each of the plurality of reaction vessels comprises at least one opening, and magnetic beads are disposed in the plurality of reaction vessels, the method comprising:
holding the reaction vessel unit with the rotor such that the at least one opening of each of the plurality of reaction vessels is directed radially outwardly relative to the horizontal rotation axis of the rotor;
centrifuging the reaction vessel unit held by the rotor by rotating the rotor around the horizontal rotation axis at a speed of rotation sufficient to wash, by centrifugation, the magnetic beads in the plurality of reaction vessels of the reaction vessel unit; and
while centrifuging the reaction vessel unit, retaining the magnetic beads in the plurality of reaction vessels by applying a magnetic field to the plurality of reaction vessels with one or more magnetic elements arranged in the rotor; and
wherein the magnetic field applied by the one or more magnetic elements is sufficient to retain during centrifugation the magnetic beads in the plurality of reaction vessels of the reaction vessel unit held by the rotor.
