Distillation is commonly used to concentrate a reaction by removing volatile solvents or reagents. Usually, operators visually check the reactor's fill level to determine the endpoints of distillation. Stopping the process too early can impact subsequent purification due to high levels of remaining volatile components, while allowing it to continue for too long poses safety risks of overheating the reactor and decomposing the target compounds. As such, accurate control of the reactor level and heating would be highly beneficial.
