The fastest, most accurate and most reliable measurements of BET surface area, porosity and pore size distribution – BET measurement every 3 seconds on TriStar systems

 

  • 3 independent analysis ports operate simultaneously – 3 BET measurements in under 20 minutes
  • Dedicated Po port continuously monitors saturation pressure during analysis
  • Surface area from 0.01 m²/g with nitrogen, with optional Krypton down to 0.001 m²/g
  • In addition to nitrogen, supports argon, CO2 and other non-corrosive gases/vapors (butane, methane)
