Abstract:
1. An apparatus for applying liquids on sample carriers, comprising: a holder for a device for receiving a liquid and from which the liquid is dispensed, the device comprising a plurality of depressions that are open at an upper end, wherein respective bases opposite the upper end of at least one, several or all depressions have at least one boring, at least one of the borings being configured in such a manner that capillary pressure in the respective boring is greater than a pressure which can be produced by the liquid in the respective depression; a mechanism for producing a gas pressure pulse disposed above the holder for the device and in fluid communication with the respective upper end of at least one or several but not all of the depressions to receive the gas pressure pulse; a holder for at least one sample carrier disposed below the holder for the device; a plurality of support elements operating to support the holder for the device, the mechanism for producing a gas pressure pulse, and the holder for the at least one sample carrier; and at least one moving mechanism for moving the holder for the device relative to the plurality of support elements, such that the mechanism for producing a gas pressure pulse may be displaced horizontally with respect to the individual depressions of the device, which are to be supplied with the gas pressure pulse, such that the depressions with which the mechanism for producing a gas pressure pulse are in fluid communication are adjustable.
