3P meso 400

The 3P meso 400 is a compact sorption analyzer with four completely independent analysis stations for the determination of BET surface area, total pore volume and pore size distributions of meso- and macroporous materials. Each analysis station can be programmed individually and started at any given time. This is achieved by four independent dosing volumes and without any time loss. Next to Nitrogen, it is possible to employ any non-corrosive gas as an adsorbate such as CO2, Ar, Kr, H2, O2, CO, NH3 or CH4. All four analysis stations can also be used as in-situ degassing stations for sample preparation.


  • 4 independent analysis stations with integrated in-situ sample degassing
  • 4 independent manifold volumes with individual pressure sensors
  • Software-assisted presentation of isotherms and kinetic data (equilibrium pressure vs. time)
  • static-volumetric analysis setup
  • State-of-the-art internal pressure regulators
  • Single-/Multipoint-BET surface area (DIN 66131, ISO 9277)
  • Langmuir surface area
  • Adsorption and desorption isotherms
  • Total pore volume and average pore radius
  • NLDFT (density functional theory)
  • Mesopore size distribution according to BJH (DIN 66134) and DH method
  • Micropore analysis (DIN 66135) according to t-plot, Dubinin-Radushkevich, Horvath-Kawazoe und Saito-Foley method
