Description
Perkin-Elmer 303-0112 Lithium Li Hollow Cathode Lamp Atomic Absorption AA 25mA
This is a Perkin-Elmer 303-0112 hollow cathode lamp (HCL) with a lithium (Li) cathode element, designed for use with atomic absorption spectrometers. Hollow cathode lamps are the standard light source in atomic absorption spectroscopy (AAS), producing a narrow emission line at the specific wavelength of the target element — in this case, lithium — to enable precise elemental analysis. This lamp is rated to a maximum operating current of 25 mA and was manufactured in the United States.

Applications
Hollow cathode lamps are the primary radiation source used in atomic absorption spectroscopy (AAS) — one of the most widely used analytical techniques in environmental, clinical, pharmaceutical, food safety, and materials testing laboratories. Each HCL is element-specific: the cathode is made from the target element (here, lithium), and when excited by electrical current it emits that element's characteristic spectral lines. The AAS instrument then measures how much of that light is absorbed by sample atoms in the flame or graphite furnace, allowing precise quantification of elemental concentrations in liquid or dissolved solid samples. Lithium analysis by AAS is common in clinical chemistry (monitoring lithium therapy for bipolar disorder), geochemical and environmental water testing, battery material research, and industrial process control. Perkin-Elmer has been one of the foremost manufacturers of AAS instrumentation and accessories for decades, and their hollow cathode lamps are compatible with their own spectrometer lines including the AAnalyst, 3100, 4100, and earlier models. Buyers should confirm compatibility with their specific spectrometer model and verify lamp intensity output meets instrument specifications prior to use.
This Perkin-Elmer 303-0112 Lithium Hollow Cathode Lamp has been inspected and appears to be in good used condition. The lamp tube is intact with no visible cracks or damage, and the blue multi-pin connector shows normal age-related oxidation on the pins but no breakage. The data label is present and legible, confirming the lithium cathode element and 25 mA maximum current rating. The original blue Perkin-Elmer storage and transport case is included. As with all used hollow cathode lamps, buyers should verify lamp output/intensity meets their instrument's requirements before use. Please view our photo set and contact us if you have any questions.
