ABSTRACT:
The invention relates to an apparatus for carrying out analyses comprising at least one incubation step and at least one separation step for separating a liquid phase from a phase, which is insoluble in said liquid phase. The apparatus comprises a plurality of reaction vessels (2), making it possible to simultaneously carry out similar working sequences with reaction mixtures in the separate reaction vessels, each of which has a porous bottom (3) connected to a separate chamber (8), the reaction vessels being able to retain the reaction mixture during the incubation steps. According to the invention, there is provided a pressure regulating system, which creates a higher relative pressure in the chambers (8) than in the reaction vessels (2). This pressure difference prevents leakage from the reaction vessels to the chambers.
