The aim of this study was to accurately quantify the benefit of adding extra layers to a capillary flow‐photoreactor using actinometry. A self‐built 3D‐printed FEP cap‐ illary mount was designed and each of the layers was evaluated separately. Experimental results showed that additional capillaries can be regarded as an augmented optical path length and that reflection and scattering are of minor importance for stacking of capillaries. To cope with the problem of precipitation of the ferrioxalate actinometer in intensified reactors, a new experimental method of conducting actinometric measurements with pulses was investigated and showed reasonable agreement. To make the results comparable to other literature‐known, mostly also improvised reactor setups, appropriate figures of merit (productivity, space time yield, energy efficiency and external photon efficiency) were evaluated.
