• This compact, powerful laboratory-size ultraviolet lamp is of major value for preliminary determination of the potential benefits of photochemical reactions in your own processes. Reactions of many types, including synthesis, decomposition, hydrolysis, hydrogénation, oxidation, reduction, polymerization, bleaching, precipitation, isomeric change, and halogenation, result from exposure to actinic radiation. The Hanovia Utility Model Quartz Lamp has proven excellent, too, for use in all phases of ultraviolet photography, i.e. "reflected ultraviolet procedure" and the "fluorescence method". It is highly satisfactory for illumination of optical apertures, for microscopy and absorption spectra studies. YOURS ON REQUEST: Valuable, informative 16-page brochure, PHOTOSENSITIZATION, a review, details facts on Photochlorination, Oxidation, Hydrolysis and Hydrogénation, Polymerization, Bromination, Isomeric Transformation, Decomposition, etc. Each subject is fully described in light of proven techniques and results with complete bibliography included. Write today for your copy without obligation. Dept.AC-2.
