Innova BET Sorptometer Model: iBET-04P

  • Analysis stations: 4-Station, fully automated operate
  • Surface Area and Pore Size by Gas Sorption
  • Adsorption / Desorption isotherm
  • Specific surface area: BET, Langmuir
  • Meso pore size distribution: BJH, Dollimore-Heal
  • Micropore area and volume: Dubinin-Radushkevich, t-Plot method
  • Micropore distribution: MP, HK, DA, DR and t-Plot
  • Total pore volume and average pore width
  • Auto Degassing: full-automatic, 4 degassing modes are selectable
  • iBET-04P series specific surface area and pore size analyzer is a high-throughput analysis instrument that should be mainly used in mesopore and macropore nanomaterials; it has advanced technology, excellent quality, more comprehensive theoretical models, and has ultra-high Stability and repeatability; large-capacity Dewar flask, which can meet the long-term analysis of materials such as micropores of 6-2nm and avoid test failure caused by the depletion of liquid nitrogen.
  • High-throughput design: four sample analysis stations with four degassing stations can be analyzed
  • Integrated design of degassing station and analysis station, and has a completely independent vacuum system and gas line; We also use composite heating furnaces to replace uneven and fragile heating
  • The linearity of the heating rate can be adjusted, the temperature control accuracy is high, and the insulation
  • Each analysis port is equipped with an independent pressure sensor, with high analysis data
  • Adopt dynamic temperature difference calibration technology to solve the impact of liquid nitrogen volatilization on volume and improve the stability of
  • The gas line control system adopts a high-precision pressure electronic control system (PFC) with a locked high-vacuum
  • Optional embedded isothermal jacket module for gas isothermal adsorption test at 0°C-60°C.
