Beschreibung
Zusammenfassung:	The apparatus makes it possible to carry out a method in which the macromolecules are separated into bands and a removal aid is placed in the gradient in the region of each band to be separated. The object of the invention is to improve the above method in such a way as to make possible the rapid and effective preparation of, for example, fluorescent nucleic acid bands from density gradients or the preparation of other substances from other density gradients which permit the visual localisation of the separated substances. The achievement is characterised in that the pipette-shaped removal aid is moved relatively to the band and the position of the removal aid in relation to the band is determined optically.
