In-Situ Research Instruments (ISRI) is a corporation dedicated to helping you with your catalyst research needs.

Our Vision.

Over time, in its own research and at the request of customers, ISRI has developed other products such as a high-pressure micro-reactor system( HP100) as well as its High-Low Pressure Infrared Reactor, patent-pending. In 1999, we first presented our first entry into the combinatorial catalysis market, the COMBI-Reactor, capable of testing ten catalysts in a single run. Now, we are continuing with our philosophy of multiple instruments in one by joining versions of all our products into the COMBI-RIG Catalyst Development System, a system as well as a methodology for discovering new catalysts. Again this is a first, offering mutliple characterization capabilities with combinatorial techniques.

ISRI has also designed and custom built units for customers with special needs in the area of catalysis and also conducts research for third parties. They can adapt your current system so that it becomes fully automated. ISRI strives to provide you the best and most cost effective solution for your catalyst and reaction characterization needs. 


ISRI has been proud to participate as exhibitors in several important conferences including:


  • 1995 EUROPACAT-II in Maastricht

  • 1997 NACS Meeting in Chicago

  • 1999 NACS Meeting in Boston

  • 2000 ICC in Granada

  • 2001 NACS Meeting in Toronto

  • 2002 EuroCombiCAT Workshop in Ischia

  • 2003 NACS Meeting in Cancún

  • 2004 ICC in Paris


We look forward to seeing you at our next conference display!

Company Profile.

Based in Indiana, U.S.A., the company was created in 1992 by Dr. E. E. Wolf, who is President. Dr. Wolf has over 25 years of catalyst research experience to place at your disposal. He has co-authored over 100 scientific papers, many dealing with in-situ methods of catalyst characterization and has three patents. From the beginning, the company has cultivated a philosophy of combining many separate, specialized instruments into one multi-functional system. This approach gives researchers more flexiblity in their work by making more tools able to them for less money than buying the individual units. More importantly, multi-functionality means the unit will constantly be in operation.
