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. 1. A sample tube comprising:a sidewall that is substantially cylindrical and open at one end and non-cylindrical and closed with a bottom at the opposite end; andnon-cylindrical surfaces formed in the substantially cylindrical end of the sidewall to be gripped by complementary gripper surfaces of a gripper, assuring proper orientation of the test tube relative to the gripper.2. The sample tube as recited in wherein the bottom end of the sample tube has a rectangular cross-section.3. The sample tube as recited in wherein the non-cylindrical surfaces formed in the substantially cylindrical end of the sidewall extend along the edges of the rectangular section at the bottom end of the sample tube.4. The sample tube of wherein the non-cylindrical surfaces are flat surfaces.5. The sample tube as recited in further comprising a barcode on the bottom end of the sample tube claim 1 , the barcode including an element to determine the orientation of the sample tube.6. The sample tube as recited in further comprising a protrusion or depression on the sidewall to orient the sample tube.7. A method of orienting sample ...
