BELSORP-miniII uses a new method for free space measurement (AFSM), which enables high accuracy and reproducible data analysis to be performed. BELSORP-miniII can be widely used for both research and QC in industry and academia.

  • Up to 3 samples can be measured independently and simultaneously.
  • Pore sizes of 0.35 to 200 nm in diameter can be measured.
  • Specific surface areas as low as 0.01 m2/g can be measured.
  • Up to 4 BELSORP-miniII units can be controlled from one computer.
  • Liquid nitrogen level control is no longer necessary by applying advanced free space measurement method (AFSM) invented by BEL, which obtains high precision and high reproducible data.
  • Very compact space-saving unit
  • ISO 9277 and JIS Z 8830 compliant
  • CE certificate
  • Automatic shutoff after several minutes of non-use
