Continuous-Flow LED Photoreactor System

Temperature-Controlled Continuous Photochemistry with Modular LED Architecture

Continuous-flow photoreactor is a modular LED photoreactor system designed to convert a temperature-controlled coil reactor into a high-power continuous photochemistry platform.

Continuous-flow photoreactor is a compact, high-power (120 W or 180 W) LED photoflow reactor system engineered for continuous flow chemistry applications. Built around a liquid-cooled LED lamp module and an FEP coil reactor, the system integrates with the Cold Coil temperature control module to deliver precise thermal management and uniform irradiation. Available in fixed wavelengths of 365, 385, 405, 420, 455 and 525 nm, continuous-flow photoreactor supports a broad range of photochemical transformations. The LED lamp module is actively cooled and automatically cuts out if the LED backplate temperature exceeds 50 °C, protecting system longevity. A mechanical safety interlock prevents illumination when the lamp is removed from the coil reactor housing. The standard FEP coil reactor (15 mL internal volume) is wound onto a grooved aluminium mandrel to ensure optimal heat transfer. An embedded temperature sensor located close to the reactor tubing enables accurate temperature monitoring via the digital PSU display or an external thermometer. The system is rated for a maximum recommended temperature of 150 °C and pressure up to 20 bar. Designed for laboratory-scale process development, continuous-flow photoreactor enables independent control of reactor temperature when paired with a suitable thermoregulating recirculator, supporting stable and reproducible continuous photochemical workflows.
