ClementAbstractTwo conduit means having a preselected volumetric relationship one to the other are utilized in the dilution of a sample by filling one of the conduit means with a diluent liquid and the other with a sample material, then connecting the two conduit means together in a closed conduit loop and circulating the contents of the loop through the loop in order to cause uniform mixing of the sample material with the diluent liquid. In a preferred embodiment the diluted sample material is resampled from the conduit loop for further use or analysis. | |
