Abstract
The invention relates to a liquid handling process that provides self-limited, controlled and gentle movement of a quantity of liquid for metering and positioning purposes without the need for auxiliary sensors, and without loss or damage to the liquid sample. Precise positioning is accomplished under the influence of progressively reduced volumes of reduced pressure in an arrangement in which atmospheric pressure produces movement of the liquid quantity without need for auxiliary sensing devices, flow or pump control mechanisms, and the like.
