Mercury porosimeter BELPORE Series
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.
The BELPORE series consists of the safest and most versatile mercury intrusion porosimeters on the market. Greatly improved, its roots reach back to the discontinued Pascal Evo (140, 240 and 440) series, formerly distributed by Thermo Fisher and Porotec.
The new BELPORE product range is now exclusively available via Microtrac.
The three mercury porosimeters from Microtrac cover different pore ranges:
Dilatometers in various sizes for measuring porous material
The professional dilatometer offers an easy and safe handling via screw cap and integrated opening aid.

The PoreInspect software for the BELPORE porosimeter series of Microtrac offers a variety of functions. The software monitors and controls up to 4 measuring instruments connected via LAN completely independently with a PC and allows for individual control of all instrument parameters in real-time.
The data evaluation of the PoreInspect software not only takes the exact blank value correction into account, but also allows for a check and correction of possible sample compressibilities, guaranteeing most reliable results. Extensive evaluation options enable the selection of different pore models and their presentation as graphics and histograms. The calculations are freely selectable depending on the application and include, for example, the representation of fractal dimensions as well as calculations of tortuosity and permeability. Overlay, statistical evaluations, the creation of a method catalogue and data export are further features. The stored raw data is available at any time.

“Pascal” is not only a pressure unit, in the BELPORE mercury porosimeter it also stands for the equilibrium-controlled and optimized handling of the pressure build-up through the so-called “Pressurization by Automatic Speed-up and Continuous Adjustment Logic”, or P.A.S.C.A.L. for short. This automatic control is regulated by the real pore system and permits shorter measuring times under guaranteed equilibrium conditions as well as the detection of all pores within the specification - and this with up to 20,000 measuring points per analysis. Since only three types of dilatometers are sufficient for all measurement tasks and neither gases nor liquid nitrogen are required, running costs can be kept significantly low.
In addition, the BELPORE LP low-pressure mercury porosimeter is easy to use and has an extended measuring range up to pore sizes of 1 mm. The vertical venting and filling with mercury on the BELPORE LP allows the degassing pressure to be adjusted, making it possible to measure moist samples without changing the moisture content of the material. In this way, even moist concrete samples and solvent-containing porous green bodies can be measured unaltered.
