The invention relates to a disposable device, in which the target substances are bound to solid carriers, preferably microparticles. A mechanism according to the invention enables the solid carriers to be easily concentrated to a volume of appropriate size. A further device according to the invention makes it possible for the solid carriers in the device to be subjected to known isolating, amplifying and/or detection reactions. The device is especially suitable for the enrichment and isolation and/or detection of substances in, or extracted from, biological liquids. The device according to the invention for obtaining, storing and processing substances extracted from liquids consists of a cylinder for holding the liquids; solid carriers; seals on both ends of cylinders which can be perforated with a hollow needle, where at least one of the seals is formed as a piston disc or can be perforated; separating membranes; hollow needles for introducing and draining liquids; and possibly a stamp for actively filling the cylinder. |
