Abstract
A method of uniquely identifying a plurality of discrete test tubes. The method includes providing a rack having an array of wells located at the intersections of mutually perpendicular columns and rows. The rack is marked to orient the rack from top to bottom and left to right. Each well is identifiable by reference to a sequence of letters and numbers identifying its respective intersecting column and row. A plurality of test tubes are positioned in the wells. The test tubes have open tops and closed lower ends protruding through the open bottoms of the wells. Indicia are applied to the respective closed lower ends of the test tubes positioned in the wells. The application of the indicia is performed in situ and simultaneously as a single step to all of the test tubes in the wells, thereby resulting in each test tube being uniquely identified with reference to its respective well.
