Autosorb instruments are high-vacuum physisorption and chemisorption analyzers that can measure BET surface area, active area, and pore size distributions. Independent analysis stations, proprietary TruZone active coolant control, and accessible Kaomi software allow users to satisfy current measurement requirements while adapting to future ones through factory and field upgradeable options. Absolute Autosorb is the clear option for the most significant gas sorption measurements.

- Obtain extremely accurate physisorption readings from relative pressures less than 10–7 for nitrogen.
- Utilize accurate manifold temperature control, ranging from 35 to 50 °C
- Even during extended analyses, rely on TruZone active coolant level management for precise results
- Superior high vacuum performance can be attained using precision-machined manifolds and premium pneumatic valves, which are 38% better than previous-generation instruments
Independent Stations Ensure Users are Agile

- Users can concurrently analyze up to three samples at different temperatures using three distinct analysis gases by employing separate analysis stations and patented temperature control accessories.
- Use six integrated degassing stations to increase throughput
- Quickly switch to the 1100 °C furnace for sophisticated temperature programmed studies, pulse titrations, or chemisorption isotherms
Intuitive Software Makes Every Analysis Accessible
