RUBOTHERM ISOSORP

Fully automated gravimetric gas adsorption system

The device is dedicated to standard characterization measurements of nano-structured matter by nitrogen sorption isotherms at 77K. The system is equipped with a micropore and a vapor sorption option and two outgassing stations for temperatures up to 350°C. The instrument data reduction sofware supports the standard data reduction algrorithms like BET, BJH, etc. as well as the  newest  DFT  kernels for typical pore geometries.

location: LS 116

Special  features

  • Sample chamber fully decoupled from balance (suspension coupling)
  • Flow and pressure controlled gas dosing system
  • Gas mixing option with 3 separate gas inlets and evaporator
  • Comfortable data acquisition software for balance and vapor dosing system
