Abstract

This invention relates to an apparatus and a process for rapidly and accurately dispensing fluids, in which at least one component is dispensed into the reaction vessel in two or three stages. In this process, the amount of fluid dispensed in the second and third stages is determined on the basis of the mass flow rate calculated in the preceding sub-step.
