A holder (2) for sample liquid containers, e.g. Eppendorf vessels (15), is horizontally displaceable between a working position above a magnetic arrangement (4) and a heating position above a hotplate (5). The latter are supported on a baseplate (3) which can be vertically displaced by means of a lifting device (9) between a lowered passive position and a raised active position in which the magnetic arrangement (4) and the hotplate (5) act on the sample liquid in the Eppendorf vessels (15) and attract ferromagnetic particles suspended there. To improve the interaction between the ferromagnetic particles and the sample liquid, the magnetic arrangement (4) can be transversely moved by a stepping motor (6) between a first position, in which, for example, a magnetic plate (14) acts on a row of Eppendorf vessels (15) from the right side, and a second position, in which said magnetic plate (14) acts on the same row of Eppendorf vessels (15) from the left side.

1. A magnetic separator comprising: a holder for at least one sample liquid container; a magnetic arrangement which is arranged underneath said holder and which can be moved, relative to the holder, at least vertically between an active position, in which said magnetic arrangement extends into the immediate vicinity of the at least one sample liquid container, and a passive position, in which said magnetic arrangement is at a distance below said container; said holder being displaceable relative to the magnetic arrangement between a working position, in which said holder lies above the magnetic arrangement, and a further position, in which said holder is horizontally offset relative to the magnetic arrangement; and a heating device arranged adjacent the magnetic arrangement in such a way that the holder, in said further position horizontally offset relative to the magnetic arrangement, occupies a heating position above the heating device.
