Flow photochemistry: Old light through new windows

Flow photochemistry: Old light through new windows

Nov 21, 2012 · An earlier example of a quartz-tubing photochemical reactor utilised a squared coil of tubing (5.0 mm o.d., 1.5 mm i.d.) 7 cm wide and 23.5 cm high . The thickness of the tubing walls was compensated for by the impressive array of 15 W LP lamps: six inside the coil and another six external.
