Abstract
A centrifuge (10) includes a flammable temperature-control medium. The centrifuge has a very simple design and nevertheless offers sufficient protection against ignition of the flammable temperature-control medium in the event of a crash, but also at standstill and during the course of operation. To this end, a first section (42) of the temperature-control media line (40), which is arranged in the area of potential electrical or electronic ignition sources for the flammable temperature-control medium, has no connection points (114).
