Features

Continuous-flow photochemical reactor

The Redeem Photo-Flow reactor combines the benefits of photochemistry and continuous-flow processes for the highest possible versatility at a competitive price. We guarantee a perfect fit by the maximization of catalyst activity and light utilization by customizing the channel depth and the optional integrated membrane. The option to trap a solid catalyst inside avoids tedious catalyst separation and together with the easy cleaning and maintenance this reduces workload and cost to a minimum. No other photo-flow reactor on the market offers such a wide range of applications and makes transitioning from batch to flow easier.

Flow Photo-Reactor

  • Combines the benefits of flow chemistry (Easy quality control, high reproducibility, intensified process and safe operation) and photo-catalysis (Atom efficiency, low temperature, renewable energy and high selectivity) to maximize your efficiency.

  • Choose the ideal channel depth and materials tailored to your specific chemical requirements. An integrated membrane or individual mixing patterns can be added if needed.

  • Scalabale photochemistry made easy with different reactor sizes for mg/h to t/y production.

  • Highly pure product as no catalyst removal step is needed. Ensures more than 8 times longer catalyst lifetime.
