Standard Pressure Reactors

The Asynt compact high pressure single reactors  are designed for bench top use and allow easy charging, product recovery, and cleaning.

In the smaller and mid-sized model the entire vessel is simply lifted out of the heater by hand! With no elaborate set up required this is a simple but very effective unit. 

Available in a wide range of standard sizes in two pressure ratings, but also available as a custom item to suit your needs.

You can also specify a custom insert to enable parallel reactions within one reactor.


  • Carbonylations
  • Hydrogenations
  • Homogeneous and heterogeneous catalysis
  • Super critical studies
  • Corrosion testing

Specification :

  • Fits on standard laboratory hotplate with temperature control via PT100
  • Use standard DrySyn base with high pressure reactor inserts for 50, 100 and 250ml reactors
  • Fail safe mechanism and bursting disc
  • Ideal for homogeneous and heterogeneous catalysis studies
  • Gas insertion feed excellent for hydrogenation reactions
  • Agitation via magnetic flea
  • Clean, safe synthesis without the requirement of oil as your heating media
  • Standard low pressure models have design pressure of 55 barg, operating pressure of 50 barg.
  • Standard high pressure models have design pressure of 200 barg, operating pressure of 180 barg.
  • 316 stainless steel


High Pressure Single Reactor,
The new MKII 125 ml PressureSyn reactor is now certificated and tested to provide a maximum working pressure of 200bar and temperature of 200C.

The easy to open clamp mechanism also features a unique Safety Key designed by the chemists and engineers at Nottingham that does not allow the vessel cover to be removed without first releasing any residual pressure. Each Safety Key and vessel clamp are unique therefore ensuring that it cannot be undone with a spare key, only the Safety Key that is used to release any residual pressure of the reactor in use will open the clamp. Even with an operator opening the standard pressure relief valve in the correct manner it is possible to have a small blockage in a valve leading to some residual pressure. This required a safety design feature to be developed for the reactors to ensure that this was not possible; therefore each Safety Key valve assembly has a pin at its tip ensuring that when extracted will leave behind a small hole for any residual pressure to be released.
Each individual reactor is tested to 400bar pressure, witnessed and certificated at this pressure by Zurich Insurance, giving our customers secure knowledge that this reactor when in use at its maximum it is actually very under stressed.
The standard safety features of PressureSyn comprise a double pressure relief system, including bursting disk and pressure relief valve.

PressureSyn units are designed to work on any magnetic hotplate stirrer; a special DrySyn adapter plate allows the secure placement of the reactors on the hotplate stirrer; together with enhanced temperature transfer and the ability to control temperature from a standard hotplate stirrer’s temperature probe.

  • Designed and engineered in the UK, from traceable certificated 316 stainless steel.
  • Design certified by Zurich Insurance for a working pressure of 200 bar and 200°C
  • Each reactor is hydrostatically tested and observed under pressure to 400 bar by Zurich Insurance.
  • Comes with a pressure relief valve, and a bursting disk as standard.
  • Unique bracket with locking clasp so the system can be easily set up and disassembled but cannot be disassembled when under pressure.
  • Pressure relief needle valve with a built in key that can be used to unlock the clasp only once any residual pressure is released.
  • Fits a specially designed DrySyn adapter base plate for use on a standard magnetic stirrer hotplate, to 200°C.
  • Stirring is carried out via magnetic stirring bar.
  • Gas inlet/outlet valve with compression fitting for attaching to steel pressure tubing.
  • Additional (spare) 1/8th npt port for customers own attachments.
  • Optional spares pack which comprises 5 additional o ring seals and compression fittings.
  • Optional digital thermometer and extension cable.

Parallel_Reactor_Asynt_Interchim_0616 Designed to be used in conjunction with a simple bench top magnetic stirrer or stirrer/hotplate

The new Asynt Parallel High Pressure Reactor is a cost effective lightweight unit suitable for numerous stirred or non stirred applications including hydrogenations and applications where air sensitive materials are used or any other reaction where pressure or temperature are required.

It offers the user to screen 10 x 30 ml reactions at pressures of up to 100 bar.

Can be used with a standard hotplate stirrer or can be customised to have multiple temperature zones.
