The ChemSCAN range from H.E.L Group comprises three benchtop parallel catalyst screening platforms designed for high-pressure reactions and heterogeneous catalysis. Available as ChemSCAN SA, ChemSCAN and ChemSCAN+, the systems offer different levels of automation to suit a range of experimental requirements.
Each platform supports 4 or 8 independently temperature-controlled reactors, with options for different vessel volumes, materials and gas handling configurations.

The following features and options are available across the ChemSCAN range, unless otherwise specified.
Vessel Types and Volumes
- Available with 4 or 8 independently controlled reactors.
- Vessel volumes from 16 to 500 mL, depending on configuration.
- Working volumes from 3 to 400 mL, depending on configuration.
- Vessel materials include 316 stainless steel and Hastelloy C276.
Temperature and Pressure
- Operating temperature: ambient to 200°C, with optional cooling to −40°C.
- Operating pressure: up to 100 bar, with optional 200 bar configurations.
- Independent temperature control for each reactor.
Stirring Available
- Magnetic stirring from 120 to 1,500 rpm.
- Indirect agitation with magnetic stirrer bars as standard.
- Suspended mechanical agitation for efficient mixing of small-scale and non-viscous samples.
- Optional overhead direct agitation for larger vessels.
- Superior mixing for homogeneous and heterogeneous catalytic gas-liquid reactions.
- Effective mixing helps ensure that gas uptake is typically controlled by reaction kinetics rather than mass transfer, supporting reliable measurements and process scale-up.
Gas and Liquid Dosing
- Configurable gas handling for pressurisation, purging and venting.
- Optional automated high-pressure liquid dosing across the ChemSCAN range.
Intelligent Software Control and Analysis
- WinISO software control enables regular data logging, multi-step recipes, parameter control, and feedback loops. The software adds a responsive intelligence to the ChemSCAN range and delivers an intuitive interface that needs only minimal training to run quickly.
- Customisable experimental plans allow automated purging, reaction, and safety steps, depending on the selected ChemSCAN configuration.
- Experiments can be designed to:
- Run reactions at the same temperature and pressure while varying the catalyst or reagents.
- Keep catalyst loads identical but vary the initial pressure.
- Run reactors with different catalyst loads, pressures, and temperatures, with the ChemSCAN+ additionally allowing independent reaction sequences, including individual feeding, purging and venting.
Safety Features
- Include automatic user-configurable reaction detection and shutdown procedures, to ensure user safety.
- Compact manifold for easy manual purge and pressurization.
- Automatic hardware and software fail-safes are installed on every system.
