Laminar flow reactors are continuous-operating tubular reactors. They enable the analysis of chemical reactions with the typical retention time distribution and set flow conditions. This equipment series that enables research with various reactor types includes the CRE-3305-06. It is possible to analyze the operation and behavior of a reactor with laminar flow in continuous operation in conjunction with the supply unit CRE-3305. The supply unit CRE-3305is equipped with a heating water circuit, all required connections, pumps, reactant tanks, and a product tank. The reactors can also be cooled when used with Water Chiller and the supply unit CRE-3305. The supply unit is used to mount the CRE-3305-06, which is secured in place by two pins. The reactor may be quickly and easily connected to the supply unit using quick-release connections. Two pumps on the supply unit continuously feed the reactants into the reactor. Laminar flow develops due to the dimensions and potential volume flows. The reactants react to create the product. After a predetermined retention time through the upper end of the reactor, the combination of product and unconverted reactants exits. Through the use of an additional peristaltic pump, the mixture is moved into a tank of the supply unit. By varying the speed of the pumps on the supply unit, the retention duration of the reactants in the reactor can be changed.
By measuring the conductivity, the conversion in the laminar flow reactor is identified. Included is a conductivity/temperature combination sensor. Temperature and conductivity are digitally shown on the supply unit’s switch cabinet. Additionally, data capture software can record and process the measured quantities (optional).
