This set-up is used to study a non-catalytic homogeneous reaction under isothermal condition. The set up consists of two feed tanks through which two reactants are fed to the reactor. The flow rate can be varied by changing the speed of peristaltic pump. It is a helical coil tube type reactor kept in a constant temperature water bath to conduct the experiment at various temperatures. Reactants enter at lower end coming out of the top of coil from where samples are collected for analysis.
