The desktop version of Reactor Lab provides a variety of chemical reactor simulations which illustrate important aspects of Chemical Reaction Engineering, CRE. The interactive simulations are useful for class demonstrations and exercises. Many labs have quizzes which provide each student with unique inputs for which they can solve and turn in to the instructor. Course notes are at the RESOURCES menu tab.

The links below are for Windows computers. For use on Mac and Linux, see the note at the bottom of this page.

The English version of Reactor Lab is the most complete version.
