1.5" and 2", coded and non-coded, single and multi-element hollow cathode lamps
The most common usage for hollow cathode lamps is as line emitters in atomic absorption spectroscopy (AAS). In the course of time, two lamp diameters have established themselves: 2" (50mm) - used by Perkin Elmer - and 1.5" (37mm) which is used by almost all other instrument manufacturers. Many lamps are available as coded, meaning that the instrument recognises the lamp at installation and automatically sets the ideal current.
In addition to the vast range of Heraeus Noblelight coded and non-coded single and multi-element lamps in both sizes we're pleased to offer our Lab-Club product line - thus, you'll find lamps for every budget !
