Abstract:
1. A sample tube for centrifuging biological samples, said sample tube having an upper end and a lower end, and comprising a g-force-sensitive label for detecting and indicating the application of a g-force, wherein at least one physical property of an area of said label measurably changes its state upon application of a g-force above a threshold value on the sample tube in a direction from the upper end of the tube towards the lower end, wherein said label is a multi-layer label comprising an area including: a first layer containing a transparent window, and a second layer comprising a first housing positioned below the transparent window, the second layer further comprising a sliding pane within an upper extension, the upper extension not being positioned below the transparent window, the sliding pane comprising one of a 1D code, a 2D code, and an alpha-numeric code on that side of the sliding pane facing the first layer, the sliding pane leaving the upper extension and moving into the first housing upon the g-force above the threshold value acting on the sample tube, thereby making the one of the 1D code, the 2D code, and the opaque alpha-numeric code on the sliding pane visible through the transparent window.
