The Amar PhotoFLO® Reactor is a continuous photochemical flow reactor designed for efficient, safe, and scalable light-driven reactions. It uses a high-intensity central LED light source surrounded by tightly wound PFA tubing, ensuring uniform illumination and maximum photon utilization throughout the reaction path. Available in volumes from 12 mL to 200 mL, with flow rates up to 10 LPH, pressures up to 10 bar, and temperatures up to 200°C, the reactor is suited for both research and pilot-scale applications. Its multi-wavelength LED options and temperature-controlled jacketed housing provide precise control over reaction conditions, improving conversion, selectivity, and reproducibility. By combining continuous flow processing with efficient photon delivery, the PhotoFLO® Reactor enables safer handling of photochemical reactions while supporting easy integration, customization, and scale-up for modern process development.
The reactor is built around a central high-intensity LED light source, with PFA tubing tightly wound around it. As the reaction mixture flows through the tubing, it receives uniform and consistent illumination along the full reactor path. This design improves photon transfer and reduces the uneven irradiation often seen in batch photochemistry. The reactor is enclosed in a jacketed stainless-steel housing with a quick-clamp arrangement, which helps with temperature management and ease of handling. This combination of continuous flow, controlled irradiation, and thermal regulation leads to cleaner and more reproducible photochemical processing.
The PhotoFLO® Reactor offers four standard LED wavelengths: 365 nm, 385 nm, 405 nm, and 415 nm. These cover a broad range of common photochemical and photocatalytic applications. The system can be configured with custom wavelength options for specialized processes, allowing users to match the light source to specific chromophores, photocatalysts, or reaction requirements. This flexibility makes the reactor suitable for a wide variety of light-driven chemistries without requiring major changes to reactor geometry.
In batch photochemistry, light penetration is often uneven. Molecules close to the lamp may be overexposed, while those farther away receive insufficient irradiation. The PhotoFLO® Reactor addresses this by ensuring uniform photon exposure throughout the reaction volume. Continuous flow also improves heat dissipation, reduces the reaction hold-up volume, and enhances overall process safety. These advantages can lead to better selectivity, improved reproducibility, more consistent product quality, and easier scale-up compared with conventional batch photochemical systems.
Uniform light exposure is achieved through the reactor’s central LED design and closely wound PFA tubing. Because the tubing is arranged evenly around the light source, all portions of the flowing reaction mixture receive a similar photon flux along the reactor length. This geometry minimizes light attenuation and shadowing effects while maximizing photon utilization. The result is more reliable and reproducible irradiation, which is critical for photochemical reactions where performance depends heavily on controlled light delivery.
Yes. The PhotoFLO® Reactor uses energy-efficient LED technology, which provides monochromatic light directly at the required wavelength and eliminates the need for filters. This helps to reduce power consumption while increasing lamp life and lowering maintenance compared with traditional mercury or xenon lamp systems. LEDs also generate less excess heat, which supports safer and more sustainable photochemical processing.
Yes. The reactor is housed in a jacketed stainless-steel enclosure that provides temperature-controlled operation. This allows efficient heat removal or addition, helping maintain stable reaction conditions and preventing localized overheating. This feature makes the reactor suitable for exothermic photochemical reactions, where thermal control is important for safety, selectivity, and reproducibility.
