Integrated Lab Solutions, Gmbh (ILS) is a Berlin-based fabricator of high-throughput testing systems for catalyst and other research systems. They frequently use Equilibar® back pressure regulators to control reactor pressure and for improved flow control of their liquids and gases.
In a recent application, ILS demonstrated highly stable pressure while passing simultaneous liquid and gas from a high pressure reactor at 300 bar (4500 psig).
The Equilibar EB1HP1 shown in the photograph is controlling the pressure of the reactor upstream. For applications in this high pressure range, SS316L or Hasteloy C276 diaphragms are typically used.
You can read customer case studies of ILS high throughput test systems in the ILS blog pages.
Quality high pressure reactors are available from manufacturers such as Parr Instruments. See other high throughput test systems available from Integrated Lab Solutions, Gmbh. See coriolis flow meters for high pressure reactors from Bronkhorst Hi-Tech.
