Abstract

A device is disclosed, being an analysis device for the study of biological or chemical samples by means of a reagent liquid supplied via a pipette. The device has an instrument housing with a base plate, a working plate arranged on the base plate horizontally to receive the samples in a sample holder having several wells, a robot manipulator arranged above the working plate, which carries a horizontal support arm with a slide. A needle system is fastened to the slide and can move in the Z direction, carrying 3 needles and being brought into vertical positions by a first vertical drive. The needle tips can be placed in an upper position above and in a lower position below a well. The middle needle can move vertically relative to the other two needles, which can be raised and lowered by a second vertical drive. The horizontal spacing of the three needles is so small that all three needles can be positioned with their tips inside the same wells. In particular, the working plate is mounted on the base plate so that it can turn.
