Abstract
An apparatus for applying liquid samples to surfaces, particularly to the separating layer used in thin-layer chromatography and comparable techniques, consisting of a guided pipette which contains the sample, can be placed on the surface with an adjustable contact pressure and which can be removed therefrom again, the apparatus having an electromagnet, the strength of the magnetic field of which can be adjusted so that it holds the vertically freely movable pipette hovering at the required height in relation to the surface, lifts it away from the surface or allows it to rest on the surface under the influence of the force of gravity.
