Abstract
A sample tube includes a barcode split into components at the bottom of the sample tube. Each barcode component stores less than the full data output from the barcode, but the components combine to full data output. Redundant diagonal components provide for error checking. A center region between the barcode components supports an electrical circuit or an optical or acoustic window. The sample tube may have a sidewall with a substantially cylindrical open end and non-cylindrical end closed with a bottom, the non-cylindrical end orienting the sample tube in a rack. Additional non-cylindrical surfaces are provided to orient the sample tube relative to complementary surfaces at a gripper. The sample tube of a particular application is positioned in an acoustic dispensing system where acoustic waves are transmitted through a center window for surveying and dispensing.
