The requirements of the system can be defined in detail by the customer. Every system is assembled and tested at our factory before installation at your facility by one of our engineers or chemists. Our systems offer unrivalled ease of use and sophisticated automation.

The High Pressure Customer Reactor Systems generally fall into one of two categories:

  • Glass High Pressure Reactor Systems: Up to 12 bar, up to 200°C
  • Metal (Stainless Steel, Hastelloy or Titanium) High Pressure Reactor Systems: Up to 60 bar, up to 500°C
Glass High Pressure Systems
  • Vessel Volume: 100ml to 1.6 litres
  • Temperature Range: -40°C to 200°C
  • Automation / Logging: Via Reactor Master PC software and/or Syrris Reactor Master series
  • Temperature Measurement: Reactor contents, jacket inlet temperature etc.
  • Pressure Range: Vacuum to +12.0 barg
  • Heating / Cooling: Jacket utilising re-circulator (optional vacuum jacket)
  • Agitation: Overhead Stirring: 50 to 2000 RPM (optional torque measurement)
  • Agitator Types / Materials: Anchor, retreat curve, 4 blade impellor etc. in glass, PTFE, stainless steel etc.
  • Liquid Feed: Volumetric dosing, gravimetric dosing
  • Gas Feed: Pressure control, gas dosing, gas uptake monitoring etc.
  • Other: Condensers, distillation assemblies, re-circulation, IR, pH measurement and control, turbidity, conductivity, calorimetry etc.


Please contact Syrris now with your specification requirements for a quotation.

Metal High Pressure Systems
  • Vessel Volume: 100ml to 10 litre
  • Temperature Range: -40°C to 300°C
  • Automation / Logging: Device management and automation using Reactor Master, Reactor Master PC Software or a combination of both
  • Pressure Range: Vacuum to 60 bar
  • Materials: Stainless steel, Hastelloy, titanium
  • Heating / Cooling: Jacket utilising re-circulator
  • Lid Design: Wide range of port options to suit your application
  • Agitation: Overhead stirring: 50 to 2000 RPM (optional torque measurement)
  • Agitator Types: Anchor, retreat curve, 4 blade impellor, gas exchange, custom design
  • Liquid Feed: Volumetric dosing, gravimetric dosing
  • Gas Feed: Pressure control, gas dosing, gas uptake monitoring etc.

Please contact Syrris now with your specification requirements for a quotation.


The following modules can be added to the basic system:
  • Gas Selection Module: Allows 3 gases to be connected. Control from the front panel or via Reactor Master PC software allows 1 gas at a time to be selected to be dosed into the reactor. Ideal for pre or post reaction purging e.g. with N2 or for multi gas reactions
  • Pressure Control Module: Automatically controls pressure to a set value. Vents in case of over-pressure. Can be set directly from the front panel ,automated from the front panel or controlled by the Reactor Master PC software

The following modes of operation are possible for both pressure reactor systems:
  • Automatically Maintain a Pressure: By using the Atlas Pressure Control Module a consistent pressure to the reaction is maintained over the reaction period.
  • Pressure Control with Mass Flow Monitoring: Maintain a pressure and monitor mass flow. Ideal for gas uptake monitoring.
  • Mass Flow Control: Dose a known quantity of gas using the mass flow controller.
  • Off Gas Monitoring: Monitor off-gases with mass flow meters.
  • Manual or Automated Gas Selection: All of the above modes of operation are compatible with the Atlas Gas Selection Module.
