The paper describes a unique device for generating ultra-high pressures in the order of 400 kilobars 40 GPa. This is a variable lateral support, Bridgeman Anvil device which uses the principle of a segmented cylinder to provide the lateral support and to apply the force to the anvils. The system has been calibrated to 212 kilobars using resistivity measurements to detect the known phase transitions in bismuth, iron, lead and 10 and 20 percent cobalt alloys of iron. A pressure of 400 kilobars, based on a linear extrapolation of this calibration, has been attained.
