Abstract

In a device for bringing a liquid sample successively into contact with a number of reagents, contact with the reagents is effected in a series of cells. These cells communicate with one another and are carried by a rotor, transfer of the liquid sample from one cell to another being effected by rotating the rotor. The direction of rotation of the rotor is reversed after each transfer operation. The number of cells constituting the series is at least equal to the number of reagents. The reagents are placed in the cells beforehand.
