CHEMBET 3000 enables the accurate, precise, and reliable characterization of powdered and porous materials using: adsorption/desorption isotherms; specific surface area measurement; pore size distribution; chemisorption analysis; solid density; etc.

CHEMBET 3000 TPR/TPD is used for the measurement of the specific area (m²/g) of nanoporous materials used for a series of specific applications: magnetic carriers, catalysts, hydrogen storage, etc., using nitrogen, hydrogen, oxygen or helium or combination of these gases. The resolution for specific area measurements is of aprox. 0.1 m²/g.
