HAN0VIA high-intensity mercury vapor arc lamps for photochemistry
Wednesday Morning, September 2 SECTION A GENERAL L. M. Chambers, Presiding Hanovia's experience in ultraviolet and quartz products over the past 50 years is responsible for a com plete line of high-intensity mercury vapor arc lamps and accessories for photochemical work on an experi mental or commercial basis. Ultraviolet radiation and near-visi ble violet and blue have already in duced a great many photo-reactions, including halogenations, oxidations, hydrogénations, polymerizations, isomerizations, nitrogen and iron reduction, and decompositions. All have been induced without hazard to personnel or damage to equipment, thanks to a completely automatic system of protective devices developed by Hanovia. Photochemical systems by Hanovia include sturdily-built immersion wells, lamps and accessories, and have been designed to fit readily with standard laboratory apparatus. The following is a partial list of lamps that are fully tested and available:
