1. A method of simultaneously transferring quantities of liquid from a first plurality of separate cells to a second plurality of separate cells, each of the first plurality of separate cells containing a liquid sample, the method comprising:

  • placing intake ends of a plurality of capillaries into the first cells so that the intake ends of the capillaries are immersed in the liquid samples the capillaries further Including discharge ends;

    aligning the discharge ends of the capillaries with the second plurality of cells;

    sealing one of said first and second plurality of cells in a pressure chamber, the other of said first and second plurality of cells being exterior of the pressure chamber; and

    creating a pressure differential between the first plurality of cells and the second plurality of cells to cause quantities of the liquid samples to simultaneously flow through their respective capillaries and to the second plurality of cells, the step of creating a pressure differential comprising inducing a change of gas pressure in the pressure chamber so that the gas pressure in the pressure chamber is different from gas pressure in the other of said first and second plurality of cells.
