AccuSorp HP (High Pressure) system is a static high-pressure gas adsorption analyzer that measures gas storage capacity, surface area, porosity, and adsorption kinetics at pressures up to 200 bar, reflecting the conditions that matter for real-world applications.
AccuSorp HP builds on more than 60 years of Micromeritics gas adsorption expertise, AccuSorp HP delivers publication-grade accuracy, automated operation, and high throughput to keep pace with the demands of modern R&D and industrial quality control (QC).
Traditional high-pressure adsorption analysis stifles productivity, requiring constant operator intervention across long analytical runs. AccuSorp HP is different, combining reliable accuracy with unattended operation and dual-sample analysis so your lab can analyze more, worry less, and trust every data point.
±0.04% full scale transducer accuracy
Blank tube tests confirm ±0.1% error at 100 bar – enabling confident measurement even with small sample quantities
Manifold temperature stable within ±0.02 °C
Kinetic data captured every 0.1 seconds
Automated elevator for dual free-space measurement
Dual servo valves achieve target manifold pressures within <1%
Restrictor plates prevent pressure overshoot, saving time and analysis gas
Touchscreen-driven stored methods that keep analyses running reliably from start to finish without the need for operator supervision
Dual analysis ports for parallel sample runs
Separate degas preparation to reduce downtime and prevent contamination risk
Compatible with dedicated degas stations, including new VacPrep (designed specifically for AccuSorp HP) and Smart VacPrep
Automated steps that eliminate mid-run interruptions – helping labs meet throughput targets with confidence
Stringent safety features ensure peace of mind for operators and procurement professionals, even when operating remotely.
Our intuitive MicroActive software generates publication-grade excess and absolute isotherms without manual post-processing. Spend less time reducing data and more time acting on it.
AccuSorp HP accommodates a range of sample tube sizes to support different sample types, quantities, and research requirements:
With ±0.1% error confirmed at 100 bar, AccuSorp HP delivers reliable data even with very small sample quantities. That is a critical advantage for researchers working with novel, scarce, or expensive materials such as MOFs, COFs, and advanced sorbents.
AccuSorp HP is a physisorption analyzer designed to deliver uncompromising precision at pressures up to 200 bar, with automation features that streamline workflows across both research and industrial QC labs.
