Patent ID: 7163660

Claim:
An apparatus for aspirating and dispensing liquid analytes, comprising: a microtitre plate with a plurality of wells for holding an analyte therein a plurality of pipettes, corresponding with each well; by which an analyte can be withdrawn from said corresponding wells if the pipettes are immersed into the analyte of the corresponding wells; at least one pump, which is coupled to a plurality of said pipettes in such a way that an analyte in each well is transferred through corresponding pipette by means of the pump, wherein analytes can be simultaneously aspirated out of a plurality of said wells or introduced into a plurality of said wells by actuating the pump; a plurality of analysis chips arranged in an intermediate plate for analyzing the analyte and a plurality of corresponding chambers; and wherein said analysis chips correspond respectively with each well in order to analyze an analyte introduced into each respective well, wherein each analysis chip comprises a plurality of liquid channels, wherein each analysis chip is arranged between a respective chamber in a flow path of the analyte from a well into a pipette and into a chamber or from a chamber into a pipette and into a well; wherein the analyte is transferred through the liquid channels of the analysis chip into a chamber or out of a chamber, respectively, and wherein a portion of a surface area of the liquid channels of the analysis chips comes into contact with the analyte, said surface area is constructed to allow biological material for binding molecules contained in the analyte to be fixed thereon.
