Abstract:
1. A device for treating or purifying sample material, comprising: a sample chamber for holding sample material, a supply chamber for holding a solvent, a reaction chamber with a separating means, for the selective, reversible or temporary binding of the sample material, a collecting chamber, for holding excess sample material and/or other liquids, a removal device for holding treated or purified sample material or other treatment products, a rotatable platform to which the sample, supply, reaction, and collection chambers and the removal device are coupled, where the rotatable platform rotates about a rotation axis, a first channel of said two or more channels having originating at the reaction chamber, extending toward the rotation axis, extending through an arcuate configuration extending to a first point of inflection at a first distance from the rotation axis, and extending away from the first point of inflection and away from the rotation axis to one of the sample chamber, the supply chamber, the collection chamber and the removal device, a second channel originating at the reaction chamber, extending toward the rotation axis, extending through an arcuate configuration to a second point of inflection at a second distance from the rotation axis, and extending away from the second point of inflection and away from the rotation axis to one of the sample chamber, the supply chamber, the collection chamber, a supply chamber, and the removal device, wherein the sample material is transferred by centrifugal forces from the sample chamber through the reaction chamber into the collecting chamber, while sample material is retained or bound by the separating means in the reaction chamber, and then the solvent is transferred by centrifugal forces into the reaction chamber, so as to dissolve retained or bound sample material, and transfer the dissolved sample material from the reaction chamber into the removal device as treated or purified sample material.
