aliquot

(in analytical chemistry) Known amount of a homogeneous material, assumed to be taken with negligible sampling error.
Note 1: The term is usually applied to fluids.
Note 2: The term aliquot is usually used when the fractional part is an exact divisor of the whole: the term aliquant has been used when the fractional part is not an aexat divisor of the whole ( e.g. a 15-ml portion is an aliquant of 100 ml). When an aliquot is taken of a laboratory sample or test sample or the sample is otherwise subdivided, the samples have been called split samples.
