Controlled lab reactor The ReactoMate Datum is a compact benchtop controlled lab reactor (CLR) system from Asynt that offers the flexibility to accommodate reaction vessels from 100 mL to 5 L. Reaction vessels from Asynt and its partner AG! can be easily exchanged on the lab reactor, allowing chemists to quickly change between reactor vessel sizes and thereby
