Independent analysis stations, exclusive TruZone active coolant control, and accessible Kaomi software let you meet your current measurement needs, while factory and field upgradeable options let you adapt to future ones. For your most important gas sorption measurements, the choice is clear: Absolutely Autosorb.

Key features

A gas sorption analyzer that’s absolutely accurate

  • Get highly accurate physisorption measurements from relative pressures below 10-7 for nitrogen
  • Leverage precise manifold temperature control between 35 °C and 50 °C
  • Rely on TruZone active coolant level control for accurate data – even over lengthy analyses
  • Achieve superior high vacuum performance (38 % better than previous generation instruments) with precision-machined manifolds and high-quality pneumatic valves

Independent stations ensure you’re absolutely agile

  • Analyze up to three different samples with three different analysis gases at three different temperatures simultaneously with independent analysis stations and patented temperature control accessories
  • Perform the most challenging physisorption measurements with the 90-hour Dewar
  • Maximize your throughput with six integrated degassing stations
  • Quickly swap to the 1100 °C furnace for advanced temperature programmed analyses, pulse titrations, or chemisorption isotherms

Intuitive software makes every analysis absolutely accessible

  • Enjoy an updated and streamlined Kaomi software, which makes the whole measurement process easier than ever before
  • Optimize measurement definition to suit your needs with DoseWizard’s new standard and advanced modes
  • Keep downtime to a minimum with PowderProtect, which prevents accidental loss of powder in the instrument

Customization options keep you absolutely adaptable

  • With 3 instruments and modular upgrades, the Autosorb adapts to the exact analysis requirements of your porous solids and catalysts
  • As your research changes, the instrument’s physisorption and chemisorption features can be field upgraded to fit new materials and applications
  • Go beyond standard measurements with enhanced chemical resistance, a built-in vapor source, thermal conductivity detector, or even a fully integrated mass spectrometer

Compliance and quality are absolutely assured

  • Comply with 20+ ASTM, DIN, and ISO standards for catalyst characterization and the evaluation of porous solids.
  • Get peace of mind with our 3-year warranty so you can avoid unforeseen costs
