Ultra-Violet Products SCT-1 Power Supply for UV Quartz Pencil Lamp 115V 60Hz

Ultra-Violet Products SCT-1 Power Supply for UV Quartz Pencil Lamp 115V 60Hz

The Ultra-Violet Products SCT-1 is a dedicated power supply designed to drive ultraviolet quartz pencil lamps used in laboratory and scientific applications. Built by Ultra-Violet Products, Inc. of San Gabriel, California, this is a compact, self-contained ballast/transformer unit that delivers the regulated current needed to operate short-wave UV pencil lamp assemblies. The SCT-1 is compatible with several UVP pencil lamp models, including the 11SC-1, 11SC-2, and 36-380.

Applications

UV quartz pencil lamps and their dedicated power supplies like the SCT-1 are used in laboratory settings for ultraviolet light applications including UV-fluorescence inspection, thin-layer chromatography (TLC) plate visualization, UV sterilization of small areas, and mineral/fluorescence examination. The quartz pencil lamp format produces short-wave (254 nm) or long-wave UV output depending on the bulb used, and the compact pencil form factor makes it useful for benchtop lab work. Ultra-Violet Products (now operating as UVP, a brand of Analytik Jena) has been a standard supplier of UV lamps and accessories to research laboratories, universities, and life science environments since the mid-20th century. The SCT-1 dates from an era when this style of plug-in ballast transformer was the standard approach to powering low-pressure mercury UV pencil lamps — a design that remained largely unchanged for decades due to its simplicity and reliability. These units are still sought by labs maintaining older UVP lamp systems and by researchers needing a simple, dedicated UV source for benchtop use.
