ABSTRACT:
An apparatus and process for obtaining an aliquot of serial liquid samples. A measured aliquot of each serial liquid sample is obtained and passed to an aliquot storage chamber with discard of the remainder of each liquid sample. A liquid collection container is provided sufficiently large for the largest single liquid serial sample with a generally vertical aliquot measurement container forming at least one aliquot measurement chamber. Each aliquot measurement chamber has a cross-sectional area in the same relation to the cross-sectional area of the liquid collection chamber as the quantity of each aliquot that is desired to bear to the liquid samples. The bottom of each aliquot measurement container is in the same general horizontal plane as the bottom of the liquid collection container. In one embodiment, the apparatus and process is operated by an aliquot valve which in a first position places each aliquot measurement chamber in communication only with the liquid collection chamber and when in a second position, places each aliquot measurement chamber in communication only with a corresponding aliquot storage chamber.
