Continuously running reactors are tubular reactors. They make it possible to produce goods in big volumes and at a constant level of quality. This device series that enables research with various reactor types includes the CRE 3304. A tubular reactor can have its behavior and operation examined. The apparatus includes a heating water circuit in addition to all required connections, pumps, reactant and product tanks, and tanks for reactants. Silicon pipe connections make it simple to connect the reactor. The reactants are delivered into the reactor individually through each nozzle by the two pumps of the supply unit.
The two reactants are combined in the T piece’s center thanks to the placement of the nozzle outlets. The two reactants are introduced into the mixture, which then enters the concentric tube. After leaving the tube, the combination of product and unconverted reactants is carried into a tank. The speed of the pumps is used to modify the reactant retention period in the tubular reactor. The water bath also houses the tube. The user may see how temperature affects the reaction because the water bath is connected to the heating water circuit. The conductivity is measured to ascertain the conversion in the tubular reactor. Included is a conductivity/temperature combination sensor. Temperature and conductivity are digitally shown. Additionally, data capture software can record and process the measured quantities (optional).
