ABSTRACT:
A wand assembly having an elongate rod with a lower end having a groove or grooves formed therein. When contacted with (e.g., touched to) a colony, the lower end is able to ingest a predetermined quantity of bacteria into the groove or grooves by capillary action. The wand assembly is particularly suitable for ingesting very small quantities of bacteria, e.g., on the order of 1.times.10.sup.7 colony forming units, since it is provided with a collar that is releasably attached to the rod, and can be detached from the rod after the lower end has been touched to a colony, in a manner that wipes excess, unwanted bacteria from the peripheral surface of the rod.
