A reactor characterized by not having inflow nor outflow of reactants or products while the interior reaction is occurring. Batch reactors are used for small-scale operations, testing new processes before they are developed further, manufacturing expensive products, and processes challenging to conduct in continuous operation. 

Batch Reactor

A reactor that is operated at steady state, with few exceptions.
