MERCURY POROSIMETER

BELPORE

The BELPORE mercury porosimeter series for low- pressure (LP), medium-pressure (MP) and high- pressure (HP) reliably and reproducibly measures pore diameters from 1mm to 3.6nm.

The knowledge of porosity, pore sizes and pore volume is of fundamental importance for the characterization of porous materials. Mercury porosimetry is the most widely used method for determining the pore size distribution of accessible macro- and mesopores in solids.

The technique is based on the pressure-dependent intrusion of mercury as a non-wetting liquid into a porous material. Using the Washburn equation, the corresponding pore size is calculated from the applied pressure.

Microtrac, as a provider of state-of-the-art solutions in the field of particle characterization and gas adsorption, has now expanded its extensive portfolio with a series of devices specifically for the field of mercury porosimetry. 

The BELPORE porosimeter series consists of state-of- the-art instruments for measuring pore size distribution, pore volume, specific surface area, porosity, density and particle distribution of finely divided and porous materials.
