Delivering on the most important requirements for any characterisation laboratory, the Autosorb series consists of three customisable instruments designed for the most challenging BET surface area, active area, and pore size distribution measurements in the nanometer range (0.35nm to 500nm).

Accuracy and agility

The instruments come with a leak-tight analysis system, precise manifold temperature control, and Anton Paar’s TruZone active coolant level control ensuring accurate detection of BET surface areas below 0.1m2 with nitrogen. In addition, the long-lasting dewar lets operators conduct measurements that exceed 90 hours without requiring a refill of the dewar.

With three independent analysis and six independent degassing stations, laboratories can flexibly analyse up to three different samples with three different analysis gases at three different temperatures simultaneously. A complete characterisation of catalysts can be performed quickly and easily by switching between the cryogen dewar and 1,100°C furnace in minutes.

Accessibility and adaptability

The Autosorb instruments come with easy-to-use Kaomi software. The included Dosewizard system helps users with measurement definition, while our new PowderProtect feature reduces the risk of sample elutriation or loss of powder into the instrument.

There are three instruments to choose from depending on the application and analysis method (physisorption or chemisorption). Furthermore, the number of analysis stations (one, two, or three) and options (Vaporsorption, CryoSync, TCD, Injection Loop, or Mass spectrometer) can be selected to match a laboratory’s measurement and throughput requirements. As needs change, modular field upgrades allow the capabilities to be changed to meet revised requirements.


The Autosorb series complies with 20+ ASTM, DIN, and ISO standards for surface area, pore size, and pore volume measurements. Anton Paar also has a global support network, so users can be sure that wherever they are, a qualified expert is nearby and ready to help.
