Discontinuously operated stirred tank reactors are typically employed when the reaction rates are extremely slow or the product amounts to be produced are small. A gadget series that enables research with several reactor types includes this small batch reactor. A discontinuous stirred tank reactor’s behavior and operation can be studied. The apparatus includes a heating water circuit in addition to all required connections, pumps, reactant and product tanks, and tanks for reactants. The reactor is attached to the device and secured in place by two pins. The reactor and the unit can be connected quickly-release connections. In the beginning of the unit, the reactants are preheated. Transfers of the reactants into the stirred tank reactor follow. By ensuring a homogenous mixture, a stirrer extends the amount of time that the reactants are in direct contact.
In an isothermal operation, a stirred tank reactor’s chambered bottom acts as a heat exchanger to study how temperature affects the reaction. By measuring the conductivity, the conversion in the stirred tank reactor is identified. The item comes with a conductivity/temperature sensor that works together. Temperature and conductivity are digitally shown on the unit’s switch cabinet.
