ABSTRACT:
Apparatus for preparing solutions of solid samples for wet chemical analysis comprising an overflow dissolving vessel divided by an overflow baffle into at least two chambers, means for maintaining a constant stream of solvent flowing successivefully through the chambers of said overflow dissolving vessel and a metering conveyor scale for continuously metering a measured amount of solid sample to be analyzed to the overflow dissolving vessel, said metering conveyor scale comprising a conveyor for continuously introducing solid sample into the dissolving vessel, a vibratory feeder for continuously supplying solid sample to the conveyor at a controlled rate and an overflow funnel for supplying a controlled amount of sample to the vibratory feeder; deflecting baffles and agitators are provided to promote mixing and dissolution of the sample and means are provided for automatically withdrawing a sample of solution for analysis from the chamber remote from the chamber into which the solid sample is introduced.
