BEL instruments for sorption measurement

BEL instruments are designed and manufactured in Japan by the BEL company, which has a long history of creating innovative, reliable, and high perfomance sorption measuring devices.

Physisorption measurements for Surface Area and Porosimetry

Multiple-sample sorption analysers, based around the patented AFSM™ method, giving best-of-class repeatability and accuracy.

  • BELSORP-max II: High performance, adaptable, and reliable sorption measurements for :
    • 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 for users who do not require the full functionality of the BELSORP-max-II
    • For high precision pure gas sorption, Krypton surface area, low pressures…
