  • What is a Batch Reactor? Definition from Corrosionpedia

    explains Batch Reactor. Batch reactors are commonly used in steel, stainless steel, glass or exotic alloy production. The liquids or solids used in the batch reactors are usually charged via connections in the reactor's top covers. Any vapors and gases generated during the process are discharged from connections in the top cover.

This allows for higher heat and mass transfer rates while simplifying maintenance because there is no agitator. The picture below is of a cell culture reactor.
