    • BET analysis, SSA, surface area,
    • Porosity, PSD, pore size distribution,
    • Microporosity, mesoporosity, powders, catalysts
    • Innovative design for the most accurate sorption measurements.
    • 3 samples in high accuracy AFSM™ mode
    • Versatile and upgradable platform with a variety of options for low area, low pressure, variable temperatures, vapours.
  • BELSORP-max-G:
    • A small footprint economic version with one sample station for users who do not require the full functionality of the BELSORP-max-X
    • For high precision pure gas sorption, Krypton surface area, low pressures…

BELPORE Mercury Porosimeters

The BELPORE instruments offer a unique capability for mercury intrusion porosimetry, adressing applications which cannot be met by any other technique. Please contact us for more details.

Chemisorption analysis

  • BELCAT II: Pulsed chemisorption, continuous flow.
    • TPO, TPR, TPD : oxidation, reduction, reaction, desorption.
    • Fully Automated flowing and pulsed chemisorption.
  • BELmetal II : Metal surface area analysis of catalyst materials.

Density Measurement by gas pycnometry

  • BEL-Pycno: Automatic helium pycnometry for determination of true density
  • New: BEL-Pycno-L for a wider range of applications, including sample sizes up to 135 cm3
