ABSTRACT:
The unit has three rotors, namely a reagent rotor (1), a sample rotor (2) and a reaction rotor (3). Each rotor has seats for vessels, which are arranged in circles about the respective rotor axis. At least two of the rotors (1, 2) are arranged concentrically to one another. The rotors can be brought into a plurality of rotating positions in which at least one of the openings (5b, 7b, 8b) is located in a predetermined liquid handling position (LH position).
A liquid handling unit (LH unit) comprises a liquid transfer needle (18) which is movable by a transfer needle moving apparatus in such a way that the movement path (23) crosses at least one LH position of each circle of openings (5b, 7b, 8b) on each rotor (1, 2, 3).
It thus become possible with a simply designed layout to carry out a wide range of heterogeneous immunological analyses in a flexible manner.
