ChemSCAN II | Catalyst Screening & Parallel Process Development System

Fast, efficient screening of 8 reactions up to 200 bar

The ChemSCAN is a dedicated parallel reaction system for the rapid development of high pressure reactions and heterogeneous catalysis systems.

An 8 reactor platform rated to 200 º C & 100 bar (200 bar option)  – with each reactor independently controlled and monitored. The sophisticated software controls allow for quick and efficient screening and development of catalytic reactions.

ChemSCAN enables rapid process development

  • Vessel sizes 16 ml, 75 ml or 120 ml
  • Independent temperature control in each vessel
  • Individual pressure control and measurement rated to 100bar (200 bar optional) with a pressure difference between reactor up to 30bar
  • On-line gas consumption calculation
  • Excellent mixing – enabling heterogeneous and homogenous catalytic gas-liquid reactions
  • Software control and logging, include all inert purges, reactive stages and with real-time gas uptake display for each reactor
  • Option for high-pressure liquid feed addition, fully automated


Independent temperature control and measurement

Each sample is separate with its own temperature sensor and controller. Thus, temperatures can be independently set and controlled with a temperature range of over 100º C at any time.

To achieve temperatures below ambient, chilled fluid must be added which lowers the operating.


Independent Stirring, measured and controlled.

Our systems are fitted individual magnets and stirrer motors under each zone. Additionally, it is possible to stir with overhead motors, normally only necessary for more viscous chemicals.


Magnetic stirring

Traditional stirring with magnetic bars (fleas) is possible in all PolyBLOCK’s, especially when small vessels or vials are used.


Suspended mechanical stirring

Good mixing of liquids and suspensions is possible using “suspended” stirrers, especially with larger vessels on the 4 position PolyBLOCK unit.


Overhead stirring

This is available as an option.

High-Pressure Reactors are most commonly 16 mL in but this is now interchangeable with 30 and 50ml reactors, all stirred and with separate temperature control. For larger volumes, up to 400 mL, bigger modifications are needed. All feature efficient magnetic stirring the following being typical choices:

  • Stainless Steel or Hastelloy wetted parts
  • Suspended mechanical agitation for efficient mixing on small scale and no-viscous samples
  • Overhead direct agitation for larger vessels (100 ml plus)
  • Up to 200 bar
  • Up to 250 ° C


Vessels to suit any scale…


16mL Vessels

16 mL Vessels available across the range, but specifically designed for chemistry screening on the HPCS unit. Each vessel is supplied with a multi-port lid and a central thermowell. The thermowell can be used to support suspended stirrers (PTFE, stainless, or Hastelloy) in order to improve mixing.

The small size is ideal for reducing chemical inventories for screening runs, and provide excellent data for selecting the chemical systems to proceed to larger-scale testing.


75, 160, 300 or 400 ml working volumes

Larger vessels ideal for High-Pressure Optimisation.

Reliable & scalable results can be obtained using suspended mechanical agitation. Suspended agitation provides a low-cost option without the chance of leaks. Where overhead motors are needed, the vessels can be supplied with magnetic rotating seals and conventional drives (75ml vessel not available with overhead agitation). This application can be extended by the inclusion of pressure measurement and control.


CAT systems

The multi reactor platforms, High-Pressure PolyBLOCK, High-Pressure ChemSCAN II, High-Pressure AutoMATE, also accommodate HEL’s range of  CATalyst screening system. These essentially manual multi-sample screening vessels have been designed to provide a simple easy-to-use tool for high-pressure reaction screening. They can be used directly in the zones of any HEL 4-pot reaction platforms, or on stirring hotplates and oil baths.

  • 18 or 24 Samples
  • 100 bar
  • 4 ml working volumes
  • Each vial independently agitated


CAT 18

Is designed to be used with 18 standard 2ml HPLC vials (with our without septa in place)


CAT 24

Is a simple device that allows the use of 24 open-top vials to be used at high pressure and temperature. Typical test volume is around 1ml. The vessels are refluxed with cold fingers that minimise solvent loss and cross-contamination.
