Abstract: The invention relates to the use of a disposable container comprising a cylindcr (1) containing a plunger (2, 24) that is displaceably guided in said cylinder and a connection (3) that is provided on a first end (E1) of the cylinder (1) lying opposite the plunger (2, 24), said container being designed to create a difference in pressure in a microfluidic device (13) to hold (6) an agent (F, P) for processing molecules and/or to act as a reaction vessel.

Abstract: The invention relates to a method for conducting the parallel identification of different nucleic acids S. When nucleic acids S are present, primers are lengthened each of which having an intermediate segment z. The intermediate segment z is amplified by using a second primer pair and is specifically identified by hybridizing with a probe So.

Abstract: The invention relates to a device (17) for detecting an analyte in a liquid having a multitude of electrodes (15), which are insulated from one another while being arranged on a first side (12) of an electrically non-conductive plate (10) that is impermeable to the liquid. Said electrodes (15) have, at least in part, an analyte-specific coating or analyte-specific molecules. Electrical conductors that pass through the plate (10) can, from a second side (14) of the plate, be electrically contacted and individually discharged. The coating or the molecules has/have a specific affinity to the analytes or to a substance formed due to the presence of the analyte. In addition, the device has no leakages.

Abstract: The invention relates to a method for carrying out a reaction in an unmoved liquid in a capillary which is open at at least one end, with gas bubbles forming in the liquid, with a detergent being added to the liquid for the purpose of changing at least one property of the gas bubbles which are being formed and with the capillary being arranged, or having been arranged, at at least an angle to the horizontal which is such that the gas bubbles in the capillary ascend to a surface of the liquid.
