The Shanghai 3S Tech Photochemical Reactor AF3 features a modular design integrating three core functions: light source, temperature control, and stirring.

 Its light source system covers a wide spectral range of 250–975 nm, supporting customizable wavelengths such as 365 nm and 405 nm, with a maximum light intensity of 1000 mW/cm² and a light decay rate below 5% per year, ensuring precise alignment with catalyst absorption peaks. 

The liquid-cooled temperature control system achieves a wide operating range of -20°C to 80°C with uniformity of ±0.5°C, eliminating photothermal interference. 

Ten independent reaction sites accommodate 2–50 mL reaction tubes, enabling independent adjustment of light intensity and stirring speed for high-throughput screening applications in pharmaceutical synthesis, environmental remediation, and advanced material development.
