Microwave Chemical Reactor. Microwave chemical reactor adopts the world’s advanced microwave power automatic frequency conversion control and non-pulse continuous microwave heating technology, and real-time monitoring of the temperature in the reaction vessel through a high-precision temperature sensor. The reactor is equipped with electromagnetic stirring mode.

Microwave reactors are equipped with pressure sealing technology, which means heating conditions above reflux are often used in microwaves. The speed at which it can reduce reaction times can be found by applying the Arrhenius law/equation: For every increase of 10 C, the reaction time is cut in half. For example, a reaction that may take a ...
