Abstract

Analysis device for analyzing samples, in particular of body liquids, with respect to components contained therein. It comprises a plurality of liquid handling (LH) stations. At at least a part of the LH stations there is a production of liquid waste whereby said LH-station form liquid waste sources. The liquid waste is evacuated, with at least one pump, from the liquid waste sources, with different proportions of air, via a liquid waste conducting system, into a liquid waste container.A substantial reduction of foam production is obtained by connecting at least two liquid waste sources to the liquid waste container via at least two liquid waste lines leading separately into the liquid waste container, whereas liquid waste sources with a higher average air proportion are connected to a first liquid waste line and liquid waste sources with a lower average air proportion are connected to a second liquid waste line.
