Abstract: A sample delivery device for delivering a particle-containing liquid comprises a sample chamber (12) provided in a syringe pump (10). The sample chamber (12) contains the liquid to be delivered. By moving a piston (14) in the direction indicated by an arrow (16) the sample liquid is, for example, fed through a tube (26) and a delivery opening (30) to wells of a titer plate. According to the invention, the sample chamber (12) is connected with a moving means (32), such as an electromotor, for preventing sedimentation of the particles contained in the liquid, and/or for preventing segregation of the sample liquid.

Abstract: A method for the labeling of molecules through the reaction of molecules to be labeled with labels at a solid phase (matrix), characterized in that the molecules enter a reaction chamber in which a matrix loaded with a reactive component is provided, and after the coupling has taken place, the labeled molecules leave the reaction chamber through a porous means.
