Hollow Cathode Lamps

Hollow Cathode Lamps are available in single and multi-element, non-coded and coded version as a direct replacement lamp for AAS Atomic Absorption Spectrometers.

Our lamps are available in 2 standard sizes, 1.5 inch (37mm) for most instrument manufacturers and 2 inch (51mm) for Perkin Elmer instruments.

Coded lamps are available for Agilent / Varian and Thermo Unicam , and data coded replacement lamps for Perkin Elmer Aanalyst range of spectrometers. Coded lamps allow the instrument to automatically identify the lamp element.

We can supply lamps for Agilent, Analytik Jena, GBC, Hitachi, Perkin Elmer, Shimadzu, Thermo Fisher and many more.
