Abstract
A liquid handling system that is particularly useful in a clinical analysis system and includes first and second storage chambers, each with a port through which liquid may be flowed into and from the storage chamber. The storage chambers and their ports are arranged to permit concurrent flowing of liquids from both storage chambers into a processing chamber. The system also includes two liquid metering means and a diluent reservoir. A valve arrangement enables connection of one of the metering means to the diluent reservoir and to either of the storage chambers; and each metering means, when connected to a storage chamber, controls flow of liquid into and out of the storage chamber through its port. The two metering means and the valve arrangement provide flexibility in selecting dilution ratios and delivering raw and diluted sample as required to an array of chambers for analysis or other processing.
