Device for receiving a test sample

A device for receiving a test sample, particularly sample holders, for combined examination of the test sample by a test procedure and another test procedure which differs from the first test procedure, with a planar preparation component in a transparent material with a preparation surface on which a test sample may be prepared, wherein a test path for the introduction of a test facility for carrying out the test procedure is formed on one side of the preparation component and another test path for the introduction of a test facility for carrying out the other test procedure on the test sample is formed on an opposite side of the preparation component and wherein a supporting and covering element which has an aperture through which the test path is formed, is pressed against the preparation component on one side;

• wherein a sealing element is arranged between the preparation component and the supporting and covering element, to make a fluid-tight connection between the preparation component and the supporting and covering element;
• the preparation component is located on a supporting component, which has a recess with a surface area which is larger than that of the aperture;
• the sealing element is extending into an area overlapping with the recess in the supporting component;
• and
• wherein a peripheral vessel wall is arranged on the supporting and covering element, and the peripheral vessel wall forming an extended sample receiving chamber, the extended sample receiving chamber is disposed above the aperture.
