- n. An apparatus for determining the proportion of oil contained in seeds, nuts, pressed seed-cakes, and other materials. It is so contrived as to allow of a small quantity of a volatile solvent being used to extract the oil, being distilled back upon the material under treatment, and filtered through it a number of times in succession. See Soxhlet's extraction apparatus.
