Method and a device for treating microparticles

摘要

Method for handling microparticles in such a manner, that at least two treatment steps are performed for microparticles in the same vessel without moving the particles to another vessel. There are organs in the device for changing the solution without having to move the microparticles to another vessel.

1. A device for handling magnetic microparticles, comprising:
(a) a vessel (26), wherein the vessel is a tube or a well; (b) a magnetic tool (10), comprising a magnet (13), a protective shield (21) or coating, a ferromagnetic sleeve (12), wherein the magnet (13) and the ferromagnetic sleeve (12) are each movable in relation to each other and wherein the magnetic field of the magnet (13) is increased when the magnet (13) is partly or completely outside the ferromagnetic sleeve (12), and a plurality of magnetic microparticles (22) contained within the vessel (26); wherein the magnetic microparticles (22) are selected from the group consisting of: ferromagnetic, paramagnetic, and superparamagnetic particles.
