This involves a device for the random arrangement of vessels open at the top in a rectangular grid, whereby the grid of vessels is bounded at two opposite-lying sides by static side walls (B), between which it can be moved as a whole with the other two side walls (A) perpendicular thereto, and there is at least one position, at which the static side walls are perforated at opposite-lying places and at least one other vessel can be moved into the grid with a guide element (C), which simultaneously retracts on the opposite-lying side, in order to take up the vessel that has been moved out of the grid, and to move it again into the grid at another place, if necessary, and thus to successively permutate the vessels.
