Custom High-Pressure Reactors

Custom high-pressure reactors from 5 mL to 50 litres plus, tailor-made to your exact requirements.

We can customise these reactors to suit your very precise requirements so whatever you need for the work you wish to carry out will be built in to the design; whether that’s temperature, pressure rating, size, chemical resistance, sampling, charging, heating, cooling… the ways that your reactor can be tailored to your needs is incredibly comprehensive so if it’s something you’re considering, please talk to one of our team today to discover what’s possible.

Materials of construction, always a critical factor in the design equation, include stainless steels – super duplex, 316 and 321 to name but a few for most standard units, and a wide variety of other grades for special duties: Ferralium, Hastelloy, Monel, Inconel, Incoloy, Nickel, Nimonic alloys, Titanium, Zirconium and alloy steels.

All our reactors are designed, manufactured and tested in the UK.

Quadracell 4 position High Pressure Reactor:

NEW: The Quadracell 4 position high pressure reactor offers users the convenience of parallel pressure chemistry in a compact footprint.
Designed to operate at temperatures up to 250 °C, the Quadracell has four cells, each with a volume of 10 mL, with material construction in your choice of either Stainless Steel 316, or Hastelloy C276 for enhanced chemical resistance if required.
The Quadracell is available to suit a maximum working pressure of 50 / 100 / 200 Bar and is supplied with a Pressure Release Valve, Pressure Gauge and 2 off Needle Valves (Stainless Steel UOS) as standard.
Designed, manufactured and tested in the UK, the Quadracell is incredibly robust and safe to use. With a wide range of factory addition options like all of the Asynt high pressure reactors, you can tailor your Quadracell to suit your individual requirements – or choose an off-the-shelf model that’s ready to use right away.

Custom High-Pressure Reactors

Designed to be used in conjunction with a simple bench top magnetic stirrer or stirrer/hotplate
The Asynt Multicell Parallel High-Pressure Reactor is a cost effective lightweight unit fabricated in 316 Stainless Steel suitable for numerous stirred or non-stirred applications. These include hydrogenations and applications where air sensitive materials are used or any other reaction where pressure or temperature are required.
As standard these offer the user the ability to screen 10 x 30 ml reactions at pressures of up to 50 bar and up to 200C, all at the same pressure and temperature.

We now offer upgrades to the system to cover a wider range of requirements:

  • Higher pressures to 100bar
  • Temperatures to 350C
  • Individual temperature control for each reactor cell
  • Alternative materials, Hastelloy, Inconnel for example.
  • Larger volumes (4 positions) to 150 mL
  • Sampling under pressure
  • Additions under pressure
  • Individual pressure setting for every reactor cell.



  • Carbonylations
  • Hydrogenations
  • Homogeneous and heterogeneous catalysis
  • Catalyst Screening, reaction optimisation & materials testing
  • Parallel synthesis
  • Super critical studies
  • Corrosion testing
