text: Microwave reactors are frequently used for small-scale batch chemistry. However, due to the extremes of temperature and pressure reached in a microwave it is often difficult to transfer these reactions to conventional non-microwave apparatus for subsequent development, leading to difficulties with scaling studies. A flow reactor with suitable high-temperature ability and pressure control can directly and accurately mimic the conditions created in a microwave reactor. This eases the synthesis of larger quantities by extending reaction time.
