Devices and methods for controlling and monitoring the progress and properti es of multiple reactions are disclosed. The method and apparatus are especially useful for synthesizing, screening, and characterizing combinatorial libraries, but also offer significant advantages over conventional experimental reactors as well. The apparatus generally includes multiple vessels for containing reaction mixtures, and systems for controlling the stirring rate and temperature of individual reaction mixtures or groups of reaction mixtures. In addition, the apparatus may include provisions for independently controlling pressure in each vessel, and a system for injectin g liquids into the vessels at a pressure different than ambient pressure. In situ monitoring of individual reaction mixtures provides feedback for proces s controllers, and also provides data for determining reaction rates, product yields, and various properties of the reaction products, including viscosity and molecular weight. Computer-based methods are disclosed for process monitoring and control, and for data display and analysis.
