Anton Paar launches new high-vacuum gas sorption analysers: Autosorb series

Published: 5-Mar-2024

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 (0.35–500 nm)

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 0.1 m2 with nitrogen.

In addition, the longlasting dewar lets operators conduct measurements that exceed 90 hours without requiring a refill. 

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 1100 °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.
