Description: Brunauer-Emmett-Teller (BET) surface areas analysis device explicitly used to elucidate intrinsic porosity as well as specific surface areas of the sample. This device predominately utilized to determine the sample’s physical properties such as the size (micro-/macro-pore) and shape (for example, square/rhombus/hexagonal shape) of pore, permanent porosity though reversible isotherms analysis (from Type-I to -IV). The standard measurements are basic nitrogen (N2) gas adsorption-desorption measurement (at 77K), and also can be possible to exchange with the other measurement gas of our interest (such as Krypton, argon, carbon dioxide, etc.). This device consists of three ports and can capable to measure up to three samples in a single run. External activation unit enable activation of pores in the sample through pre-vacuum- and -thermal treatment (at desired temperature), maximum temperature reachable up to 400 oC.


  • This device very efficient for both micro- and macro-porous samples
  • Surface areas as low as 0.01 m2/g can be measured with the standard nitrogen system.
  • Can be able to reach very low vacuum up to 1.7*10-4 Torr.
  • External Activation stage (consists 6-ports) and the temperature control from rt to 400 oC
  • Long duration cryogen Dewar (2.75-L) that can last up to 48 hours measurement time
  • Can possible to collect to 1000 data points (can able to get very nice isotherms)
