A high pressure CuBe cell with B4C anvil has being developed since 2004 for small- and wide-angle synchrotron x-ray scattering experiments under hydrostatic pressure up to 2GPa, at room temperatures. Recently, an optimized version of this cell was used to measure the pressure effect on morphology structure of orange juice particles in SAXS beam line at Laboratório Nacional de Luz Sincrotron - LNLS - Campinas. It was observed that above 500MPa the particles change its morphology. This cell has also been applied to investigate solid samples behaviour and the structure of  Cardanol-Furfural-PAni Green Blend under external hydrostatic pressure in SAXS beam line at Laboratório Nacional de Luz Sincrotron - LNLS - Campinas. Moreover, it might also be used to investigate biological system as lipid-water dispersions without changes in its design. Magnetic field up to 1.6 kGauss can be applied together the hydrostatic pressure in this cell, taken into account there is no magnetic signal from de CuBe, B4C anvil, and CuBe gasket used. Investigations about ReO2 behaviour under hydrostatic pressure up to 1.6 GPa were performed at LNLS-XPD and XAFS Synchrotron beam line, and the results revealed to be the ReO2 a good inner gauge pressure for 8keV-13keV energy range.
