Flow chemistry - Wikipedia

Continuous reactors are typically tube like and manufactured from non-reactive materials such as stainless steel, glass and polymers. Mixing methods include diffusion alone (if the diameter of the reactor is small e.g. <1 mm, such as in microreactors) and static mixers.Continuous flow reactors allow good control over reaction conditions including heat transfer, time and mixing.
