Having identified inconsistencies when repeating literature examples of photochemical transformations and difficulties recreating experimental setups, we devised several criteria that an ideal labscale reactor should achieve. Herein, we introduce a versatile photoreactor for high throughput screening, preparative scale batch reactions and continuous processing, all with a single light source. The reactor utilizes interchangeable arrays of pseudo-monochromatic high-power LEDs in a range of synthetically useful wavelengths, combined with excellent temperature control. Moreover, light intensity can be modulated in an accurate and straightforward manner. This system has subsequently been tested on a range of literature methodologies.
