Abstract

Method of separating a component of a liquid from other components by immobilizing the component to suspended magnetic particles in a vessel, immersing a magnetic device into the vessel while the device is separated from the liquid by means of a protective sleeve made of a non-magnetic material. Then the non-immobilized components are removed. The invention also addresses a device suitable for implementing this method. With said method and device, resuspension is achieved in a simple and efficient manner.
