Synthesis reactors and automated lab reactors provide an innovative platform for chemical synthesis, development, and the kilo lab. These chemical synthesis and process development tools open new possibilities to discover synthetic pathways, explore conditions, and optimize reaction parameters. Depending on the operating volume and the goal of the investigation, researchers choose between different versions of synthesis reactors or automated lab reactor control systems. The reactor control system coordinates the monitoring and control of temperature, dosage, and mixing through the use of reactor flux and thermal power measurements, reactivity control devices, and a collection of control system programs.
