A holder ( ) for sample liquid containers, e.g. Eppendorf vessels ( ), is horizontally displaceable between a working position above a magnetic arrangement ( ) and a heating position above a hotplate ( ). The latter are supported on a baseplate ( ) which can be vertically displaced by means of a lifting device ( ) between a lowered passive position and a raised active position in which the magnetic arrangement ( ) and the hotplate ( ) act on the sample liquid in the Eppendorf vessels ( ) and attract ferromagnetic particles suspended there. To improve the interaction between the ferromagnetic particles and the sample liquid, the magnetic arrangement ( ) can be transversely moved by a stepping motor ( ) between a first position, in which, for example, a magnetic plate ( ) acts on a row of Eppendorf vessels ( ) from the right side, and a second position, in which said magnetic plate ( ) acts on the same row of Eppendorf vessels ( ) from the left side.
