BELSORP-max

(Available in: Singapore, Malaysia, Thailand, Indonesia and Vietnam)

BELSORP-max is designed to measure wide range adsorption isotherm for surface area and pore size distribution analysis. It can measure adsorption isotherms from relative pressure as low as 1 x 10-8 (N2 at 77K, Ar at 87K), using a 13.3Pa pressure transducer. With the new method of free space measurement (AFSM), adsorption can be measured with high accuracy. BELSORP MAX, high-end adsorption instrument that provides all the researchers in any field and industries with useful information for surface characterization.

FEATURES:
  • Accurate wide range pressure measurement - from extremely low pressure to 133kPa
  • Multi sample measurement - equipped with 3 independent analysis ports.
  • Multipurpose - variety of gases and vapors can be used as adsorptive.
  • Chemisorption option
  • Thermostatic air oven
