What the BELPORE is

The BELPORE is a series of mercury porosimeters from Microtrac. Mercury does not wet the sample, so it enters a pore only under pressure, and the narrower the pore, the higher the pressure it takes. The instrument raises the pressure step by step and records how much mercury goes into the sample; the Washburn equation turns each pressure into a pore diameter. The series has three instruments. The LP degasses the sample, fills the dilatometer with mercury and measures the large pores at low pressure. The MP and HP take over for high-pressure porosimetry and reach the small pores. They do not run on their own: every sample passes through the LP first, so a BELPORE is configured as LP + MP — for larger sample volumes such as concrete or mortar — or LP + HP, for the full range from over 1 mm down to 3.6 nm. From the intrusion curve the BELPORE reports pore size distribution, pore volume, specific surface area, porosity, density and particle size distribution.

Which dilatometer for which sample

Three dilatometer types cover all measuring tasks. They stand vertically in the instrument for safe handling.

Type Capillary · volume · max. solid sample (d × h) · fits
Standard 3 mm · 15 cm³ · 12 × 46 mm · LP, MP, HP
6 mm · 35 cm³ · 25 × 25 mm · LP, MP
Professional 3 mm · 8 cm³ · 11 × 35 mm · LP, MP, HP — screw cap and integrated opening aid
Ultra-macropore (UMP) 6 mm · 50 cm³ · 25 × 25 mm · LP

All three take powders and solids. PoreInspect corrects for the blank value and checks and corrects for sample compressibility, then offers pore models, fractal dimension, tortuosity and permeability. The raw data stays stored.

Three instruments, one pore range

BELPORE LP — low pressureDegassing, mercury filling and low-pressure porosimetry, vacuum up to 450 kPa. Pores 180–3.25 µm, up to 1 mm with the UMP set. The degassing pressure is adjustable, so moist samples such as concrete or solvent-containing green bodies are measured without changing their moisture content.
BELPORE MP — medium pressureHigh-pressure porosimetry from 0.1 to 228 MPa, for pores from 15 µm down to 6.5 nm.
BELPORE HP — high pressureHigh-pressure porosimetry from 0.1 to 414 MPa, for pores from 15 µm down to 3.6 nm.

Pressure build-up is controlled by P.A.S.C.A.L. — Pressurization by Automatic Speed-up and Continuous Adjustment Logic — which follows the real pore system. That shortens measuring time while keeping equilibrium conditions. Filling is fully automatic and vertical under constant high vacuum, and the mercury cleaning set lets you reuse the mercury.

Where the BELPORE stops — and what to take instead

Mercury intrusion measures pores that are open to the surface, from 3.6 nm up. For micropores and the smallest mesopores, and for BET surface area by gas adsorption, look at the BELSORP MINI X or the BELSORP MAX X. For true (skeletal) density by gas displacement there is the BELPYCNO. And the BELPORE works with elemental mercury: your lab has to handle, store and dispose of it under its own EHS rules.

What usually stops people — and the honest answer

“We would rather not have mercury in the lab.”Mercury is what the method needs. The BELPORE fills automatically under vacuum, the dilatometers stand vertically, the professional dilatometer closes with a screw cap, and the cleaning set lets you reuse the mercury. Your lab’s EHS rules for mercury still apply.
“We already have gas adsorption.”The two methods meet in the middle. Gas adsorption describes micropores and small mesopores; mercury intrusion covers mesopores and macropores up to 180 µm, or 1 mm with the UMP set. Many porous materials need both.
“Which instruments do we need?”Always the LP — it degasses and fills every sample and covers the large pores. The MP or HP cannot run without it and adds the small pores: LP + MP down to 6.5 nm for larger samples such as concrete or mortar, LP + HP down to 3.6 nm. Send a sample — the test analysis is free — and the report shows where your pores sit.
“Our samples are moist.”On the LP the degassing pressure is adjustable, so moist concrete and solvent-containing green bodies can be measured without changing their moisture content.

Common questions

Don't see yours? Email [email protected] — NDA on request, typical reply within 4 hours.

What pore size range does the BELPORE cover?
The BELPORE series measures pore diameters from 3.6 nm to 1 mm. The LP covers 180–3.25 µm, or 1,000–3.8 µm with the Ultra-Macropore Set; the MP covers 15 µm to 6.5 nm at up to 228 MPa; the HP covers 15 µm to 3.6 nm at up to 414 MPa. The MP and HP do not run on their own: every sample is degassed and filled on the LP first, so a system is LP + MP or LP + HP.
How does mercury porosimetry differ from gas adsorption?
Mercury porosimetry measures the accessible macro- and mesopores by forcing a non-wetting liquid into them under pressure. Gas adsorption, as on a BELSORP, measures micropores and small mesopores and gives BET surface area. The two cover different parts of the pore range, so many labs use both.
How accurate and detailed are the results?
Pressure detection accuracy is better than 0.1% F.S. and volume detection accuracy better than 1% F.S. An analysis records up to 10,000 intrusion and 10,000 extrusion points, and P.A.S.C.A.L. pressure control keeps equilibrium conditions while shortening the measuring time.
What does PoreInspect provide beyond pore size?
PoreInspect controls up to four instruments over LAN from one PC, corrects for the blank value and for sample compressibility, and offers pore models, fractal dimension, tortuosity and permeability, as well as particle size evaluation, overlays, statistics, a method catalogue and data export. The raw data stays stored.
What sample cells (dilatometers) are available?
Three types. Standard: 3 mm capillary with 15 cm³ (LP, MP, HP) or 6 mm with 35 cm³ (LP, MP). Professional: 3 mm capillary, 8 cm³, screw cap and opening aid (LP, MP, HP). Ultra-macropore: 6 mm capillary, 50 cm³ (LP). All take powders and solids.
What about mercury safety and handling?
The BELPORE uses elemental mercury, which your lab must handle, store and dispose of under its own EHS rules. The instrument fills automatically and vertically under constant high vacuum, the dilatometers stand vertically, and a mercury cleaning set allows the mercury to be reused. It needs no gas connection and no liquid nitrogen.
Can the BELPORE measure moist samples?
Yes, on the LP. Its degassing pressure is adjustable, so moist samples — for example concrete or solvent-containing porous green bodies — can be measured without changing their moisture content.
How much does a BELPORE cost?
The price depends on the configuration — the LP with the MP or the HP, plus dilatometers and accessories. Request a formal quotation and you receive configuration, price, payment terms and lead time on our letterhead. Installation and on-site operator training are included in every quotation.
Can I test my sample before buying?
Yes, and the test analysis is free. Send a representative sample; it is measured in Microtrac's US application lab and you receive the pore size report, which we go through with you before you decide.
What is the lead time, and who installs the BELPORE?
The BELPORE is configured to order. Lead time is from 4 weeks after a confirmed order, depending on the configuration, and the formal quotation states the date. Installation and on-site operator training by Microtrac's US service engineers are included in every quotation.
