DEFINITION

Classification: 73/61.68

Including detail of fluid handling means, sampling, sample handling, or sample preparation:

(under subclass 61.65) Subject matter combined with sampling means wherein significance is attributed to means for obtaining a predetermined amount of a liquid to be tested, for treating a liquid sample in preparation for its analysis or for isolating individual components of a liquid prior to analysis thereof and/or to means for confining, directing, or controlling the flow of liquid material.

(1) Note. "Sampling" includes: (a) Transporting or handling previously obtained samples of liquid in preparation for analysis; or (b) introducing previously obtained liquid samples in preparation for analysis; or (c) the preparation of a liquid sample prior to the analysis thereof.
