UOSlab®  photochemical reactors are modular parallel synthesis systems, with high power LED light sources available in a range of wavelengths from 365nm to 525nm, reaction vessel holders from 8 ml vials to 100 ml bottles, efficient and stable liquid cooling and a user-friendly touch-screen interface..

Our reactors have been used used for UV-initiated 2+2 additions, visible light photoredox, in scales from multi-vial parallel synthesis to high-throughput pilot scale photochemistry in flow, including gas-liquid reactions. If you are not sure how well our reactors will perform in your process - send us an e-mail. we can test your reaction before you commit to buy.
