Abstract
A liquid handling system useful in apparatus for analyzing biological liquid specimens or the like includes a plurality of sample metering chambers, a distribution manifold connected between a sample inlet port and the sample metering chambers, and a corresponding plurality of auxiliary liquid metering chambers connected to corresponding auxiliary liquid reservoirs. Liquids are flowed from the sample inlet port through the distribution manifold to the sample metering chambers and from auxiliary liquid reservoirs to the auxiliary liquid metering chambers under the influence of reduced pressures which are selectively connected to the flow network through an integrated valve array and reduced pressure manifolds.
