Abstract
Two 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.

Apparatus comprising:
- first conduit means having a passageway therethrough with a first internal volume;
- second conduit means having a passageway therethrough with a second internal volume, said second internal volume having a predetermined size relationship to said first volume;
- means for filling said passageway of said first conduit means with a diluent liquid;
- means for filling said passageway of said second conduit means with a sample material;
- means for connecting said passageway of said first conduit means and said passageway of said second conduit means to form a closed conduit loop;
- and
- means for circulating said diluent liquid and sample material through said conduit loop to cause mixing thereof.
