Abstract: Liquid samples containing for example differerent combinations of DNA and markers are subjected to various processing steps, for examle exposure to different temperature baths. A flexible band is used that contains a series of cavities arranged along a longitudinal direction of the flexible band. The liquid samples are inserted into the cavities and the band is subsequently fed through a succession of processing stations. The band extends through the stations when the processing steps of the stations are applied. By advancing the band the samples are subjected to successive processing stages. At the end of the process the band may be disposed of, for eexample after extracting the samples.

Abstract: The present invention relates to a method and a device for contacting a microfluidic structure. The device comprises a receptacle for the microfluidic structure and also a contact unit. According to one aspect of the invention, the contact unit has at least one hollow needle, which is designed for piercing a layer of elastic material which is provided on the microfluidic structure.
