A micro sample tube is disclosed which is of a standard size on the exterior, but which has a reduced internal volume. A slope of an inner wall of the sample tube is a second order or higher curve, and is preferably a circle. Dead volume is reduced, and standard barcode labels can be used, due to the restricted internal dimensions and standard external dimensions. The curved inner wall of the sample tube, and an internal length of the sample tube which is the same as a conventional tube, reduces the likelihood of a sample probe of an automated analyzer impacting on an inner surface of the sample tube and potentially gouging the tube and/or damaging the automated probe. In a preferred embodiment, fins extend around said tube for reduced weight and improved heat transfer of the micro sample tube.

Microsample tube with reduced dead volume and barcode capability

A sample rack with at least one receptacle for the accommodation of respective sample tubes. At least one receptacle has a removable adapter sleeve located within it for receiving a corresponding sample tube. Additionally, locking means are included for fixedly engaging the adapter sleeve within the corresponding receptacle.
