Abstract A tubular sample or reagent container for analytical devices, such as automated centrifugal analyzers, in which typically a multiplicity of such containers are arranged in a carrier plate or other means which forms part of the analyzers, with each container having a peripheral edge for bearing on the carrier plate. An abutment is provided on the containers disposed below the peripheral edge and at the periphery of the containers, which abutment is deformable in the centripetal direction.
