A Rotating Multi-Anvil Press constructed by Max Voggenreiter GmbH is installed in the high-pressure hall of the GFZ. The apparatus consists of an 800 tons hydraulic press and a Walker-type multi-anvil module. The whole apparatus is rotatable by 360° perpendicular to the press axis. Schmidt and Ulmer (2004) demonstrated that by rotation it is possible to overcome common fluid/solid or melt/solid separation during high-pressure experiments. The press covers the pressure range 3.0-23.0 GPa, corresponding to earth's depths of circa 100-650 km, thus allowing the study of geomaterial properties and geochemical processes at mantle conditions.
