Disclosed is a device as an analysis apparatus for analyzing biological or chemical samples by means of a reagent liquid that is fed using a pipette. Said device (1) comprises an apparatus housing (2) with a base plate (10), a working plate (11) which is horizontally arranged on the base plate in order to hold the samples in a sample receptacle containing several wells (13b), and a robotic manipulator (25) which is disposed above the working plate and supports a horizontal supporting arm (26) that has a carriage (30). A needle system (31) that can be moved in the Z direction, supports 3 needles (45, 46, 47), and is moved into a vertical position by means of a first vertical drive unit (40) is mounted on the carriage (30). The needle tips (34) can be placed in a top position above a well and in a bottom position within a well. The central needle (45) can be vertically moved relative to the two external needles (46, 47), being raised and lowered by means of a second vertical drive unit (41). The horizontal distance between the three needles is so small that the tips (34) of all three needles can be placed within the same well. In particular, the working plate is rotatably mounted on the base plate. |
