DEFINITION

Classification: 73/61.59

With detail of sampling, sample handling, or sample preparation:

(under subclass 61.43) 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.

(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.
