HANOVIA high-intensity mercury vapor arc lamps for photochemistry
Hanovia's experience in ultraviolet and quartz products over the past 50 years is responsible for a complete line of high-intensity mercury vapor arc lamps and accessories for photochemical work on an experimental or commercial basis. Ultraviolet radiation and near-visible violet and blue have already induced 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: Lamp Model
