ABSTRACT:
An automated evaporator for use in chemical analysis that enables unattended solvent addition and evaporation. The evaporator comprises a heated water bath; a carousel adapted for holding a plurality of sample containers in the water bath; a manifold distributing a drying gas into the sample container to reduce oxidation and facilitate evaporation of the solvent; a turntable for rotating the water bath, the carousel and the manifold; and a stationary solvent reservoir adjacent to the water bath for adding solvent dropwise into each sample container as it passes under the nozzle of the reservoir. During rotation of the carousel, each sample container periodically passes under the reservoir nozzle for a predetermined amount of time to receive a predetermined amount of solvent. The solvent of each sample container is evaporated by the time the solvent is again added.
