The mercury porosimetry technique is one of the most useful methods to investigate the porous structure of solid samples in a quantitative way. It provides reliable information about pore size/volume distribution, particle size distribution, bulk (envelope) density and specific surface for most porous solids. The main highlights of the Pascal series porosimeters are exceptional speed of analysis and high resolution. The Pascal systems are widely used in both QC/QA labs as also in Research and Development sectors. The Pascal system, therefore, provides accurate results independently from the sample nature and/or the operator’s experience. In addition, our dedicated software fully controls the instruments and easily generates reports in a variety of formats.The Pascal 440 the highest-pressure model of the Pascal line and reaches its maximum pressure of 400 MPa in the same time as the Pascal 240 reaches its maximum of 200 MPa. The easy-to-use control panel with a liquid crystal display allows operating the unit even without a PC connected. The Pascal 440 incorporates a totally new pressurization system, developed to meet the sophisticated analytical requirements of laboratories working with modern materials.
