Introducing AccuSorp HP
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).
Characterization at process-relevant conditions
The AccuSorp HP physisorption analyzer characterizes your materials at operating pressures up to 200 bar, so your lab data can help predict real process performance. Make data-backed decisions to optimize processes across applications such as gas storage, separation, carbon capture, and more.
More high-pressure adsorption data. Less pressure on your operators.
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.
AccuSorp HP is designed for laboratories that need reproducible, high-pressure adsorption data at scale, without the complexity of traditional research systems.
Accuracy you can publish
- ±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
True walk-away automation
- 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
Throughput that keeps you on target
- 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
Risk-free operation for worry-free deployment
Flammable Gas Detector
Automatically shut down the system and vent to safe pressure when 1% concentration is detected, below the LEL of hydrogen and light hydrocarbons
Two mechanical relief valves
Set to 207 bar and 2 bar to protect against over-pressurization
Locking mechanical door
Prevents interference while system is pressurized and when hot or cold temperature control devices are in use.
Certified safe for global deployment
Third-party CE declaration and ETL Mark (NRTL) conforms to Pressure Equipment Directive (PED) 61010-1
Smart software. Seamless decision-making.
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.
- Excess and absolute isotherms automatically generated for publication-ready outputs
- IAST (Ideal Adsorbed Solution Theory) and HOA (Heat of Adsorption) calculations built in for deeper material insight
- Remote connectivity for monitoring analysis status or reviewing data from any location
- Automatic data export to XLS, TXT, and PDF formats for seamless reporting and LIMS integration
Engineered for your sample
AccuSorp HP accommodates a range of sample tube sizes to support different sample types, quantities, and research requirements:
- Two 2 cc analysis chambers (standard and alternative configuration)
- 10 cc analysis chamber for larger or lower-density samples
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.
Whether you’re researching novel materials or performing high-throughput production QC, AccuSorp HP delivers real efficiency gains across applications, backed by our more than 6 decades of expertise as a global leader in gas adsorption.
