摘要：: <p>The invention relates to a device for controlling the amount of liquid substances received and discharged. It is an object of the invention to produce a device, enabling a plurality of different liquid substances to be received and discharged from micro or nano titer plates. According to the invention, it is possible to carry out one or more chemical or biological reactions in said device and to receive liquid substances with differing viscosity, as a result of capillary channels which are arranged at an equal distance from each other and are provided in a row, said channels being brought together in a communicative link with a chamber which is can be impinged upon by overpressure and underpressure, whereby the capillary channels are embedded in the plate and one sieve-type membrane is associated with the ends of the capillary channels at least on the inner side of the pressure chamber. According to the invention, an area is provided above each end of the capillary channels for receiving a liquid substance. Said areas are arranged separately from each other and are disposed inside the chamber which can be impinged upon by high and low pressure.</p>
