ABSTRACT:
The invention relates to a cuvette rotor having at least one radially extending cuvette with a first chamber, a second chamber and a third chamber, the first chamber being located at a central location on the rotor, the third chamber being located at a peripheral location on the rotor, and the second chamber being located between the first and third chambers. The cuvette is defined by a top wall, a bottom wall, and side walls. A first barrier defines a boundary between the first and second chambers, and a second barrier defines a boundary between the second and third chambers. First, second and third ports are disposed in the top wall of the cuvette above the first, second and third chambers, respectively, and a first deflector is disposed between the first and second ports and connected to the top wall of the cuvette. Similarly, a second deflector is disposed between the second and third ports and is connected to the top wall of the cuvette. Finally, at least one vessel having top and bottom walls is arranged on the rotor adjacent the cuvette, the vessel being separated from the cuvette by a side wall, and the top wall of the vessel including a fourth port.
