The new Asynt Parallel High Pressure Reactor is a cost effective lightweight unit 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. These offer the user to screen 10 x 30 ml reactions at pressures of up to 100 bar as standard but this can be extended with customisation options. This parallel reactor can be used with a standard hotplate stirrer or can be customised to have multiple temperature zones. There are a wide variety of factory options available to customise this versatile parallel reactor, from facilities for internal cell measurement, sealed sample/additions valves, condenser jackets, electrical heating options, liquid charging systems, gas supply/mixing systems, air driven stirrer, purged chamber for heaters, and many more. We can also build these reactors from alternative materials, allowing for greater heat capacity and use with particular chemicals.
