Sports drugs testing. Laboratory technician's hand holding a sample tube in an automatic mixer. The pressure of the tube sets the mixer vibrating at a speed set by the dial (lower right). This mixes the liquid in the tube, ensuring even and complete mixing. A bottle of water is on the bench in the background. This test is for the presence of a banned drug in a sample provided by a sportsperson. This is the anti-doping laboratory of the All-Russia Research Institute of Physical Culture and Sports. Photographed in 2005, in Moscow, Russia.
