A multifunction centrifuge consists of a rotor 1 to which a plurality of centrifuge bowls 2 are rigidly fixed. Each bowl 2 has two chambers 3a, 3b connected with each other for free flow communication from either chamber to the other. One chamber 3a lies above the other 3b and is of a sack shape with a radially outwardly projecting closed bottom so that on stoppage of rotor rotation liquid therein flows back into the more deeply-lying other chamber 3b. The bowl 2 is light-transparent for photometric measurements.
