DEFINITION

Classification: 435/30

Methods of sampling or inoculating or spreading a sample; methods of physically isolating an intact microorganism:

(under subclass 29) Processes in which (a) a series of sampling steps are claimed in which a sample containing a microorganism is separated or recovered from a larger body of material before or while performing a measurement or test, or (b) a sample is brought into contact with a measuring or testing media to result in a particular geometric pattern or at a particular varying flow rate.

(1) Note. This subclass provides for sampling when claimed by a series of sampling process steps, i.e., not sampling by name only.

(2) Note. This subclass provides for applying the sample in a particularly claimed varying flow rate or pattern or path other than merely a single straight line.

(3) Note. Mere nonpattern applications such as dipping or spaying is not included herein.

(4) Note. Included in this subclass is a test or measurement which includes a swab streaking procedure or centrifugal density separation step.
