Vapourtec’s LED module, designed to complement their continuous stirred tank reactor (CSTR), enhances the potential of flow photochemistry and increases the scope for novel reactions.
The module enables reagent-less reactions even when solids are present. This is achieved by using CSTRs. Each LED module has an input power of 70W and delivers a radiant power up to 40W. It is dimmable in the range 10% to 100% of maximum power with wavelengths from 365nm and 700nm available for photochemical CSTR.
Using a CSTR for photochemical reactions improves the handling of solids and enables the use of solid catalysts, solid stoichiometric reagents or the delivery of reactions that produce either solid products or solid by-products.
The photochemical CSTR is designed to be operated as a cascade thereby enabling continuous flow reactions to have well controlled residence time distribution.
The use of two Vapourtec R4 reactor heaters allows a photochemical CSTR cascade of up to eight reactors within an R-Series flow chemistry system, providing the perfect platform for the scaling-up of photochemical reactions, even when a mix of solids and liquids are involved.
