Abstract

The present invention provides a device for carrying out a heterogeneous reaction for the determination of a component of a sample liquid on a first capillary action carrier present in a measurement chamber, to which carrier adheres at least one non-soluble reagent, wherein at least one soluble reagent is present on a second capillary action carrier in a first pre-chamber, which carrier is in capillary contact with the capillary action carrier in the measurement chamber, which first pre-chamber is connected via a first capillary with a first application chamber to be filled from outside through a filling opening and the measurement chamber is also connected with a waste chamber by a capillary arrangement through which can only flow a liquid under a predetermined gravitational force into the measurement chamber.
