Sonntek LH-1 Deuterium Lamp

The Sonntek LH-1 Deuterium Lamp is a D2 ultraviolet light source designed for use in UV spectrophotometers and detector systems, delivering the UV emission needed for spectral measurements and instrument performance. Within Sonntek’s LH family, the LH-1 is recognized as a deuterium lamp that serves as the UV light element in analytical instruments, typically used as a replacement lamp in spectrophotometer and detector configurations. This lamp is associated with the Sonntek lineup that includes a range of deuterium, tungsten, xenon, and mercury lamps, all aimed at providing reliable UV or broad-spectrum illumination for laboratory instrumentation. Common applications encompass UV spectrophotometry and UV-detection workflows in HPLC and other analytical detectors, where a stable UV output is essential for accurate wavelength discrimination and qualitative/quantitative analysis. Because Sonntek supplies LH-series lamps for multiple OEM platforms, exact compatibility depends on the instrument model and the intended lamp/holder configuration; verifying the correct match with Sonntek’s official product pages or a qualified distributor is advisable before purchase. The LH-1 designation identifies this specific lamp model within Sonntek’s catalog, emphasizing its role as the UV lamp component of the replacement assembly rather than a complete lamp-and-holder package. This makes the LH-1 a focused replacement option for laboratories seeking to restore UV illumination in compatible Sonntek-equipped systems.
