Hollow Cathode Lamps

We offer the full range of coded and uncoded hallow cathode lamps for Varian, Perkin Elmer, Thermo/Unicam and GBC instruments. The uncoded 1.5” lamps are compatible with most instruments.

Contact us with the make and model of your instrument and we will ensure compatibility.




Hollow Cathode Lamps are directly used in the following AAS systems: Agilent, Varian, Analytic Jena, Thermo Fisher, GBC, Shimadzu, Hitachi and many more. Cathodes are designed with either a pure element or compound to produce the best sputter rate at the lowest current. To enable a lamp to run the most economical way possible.
Note: Increasing lamp current increases the sputter rate and deceases lamp life, sensitivity and linearity. Hollow cathode lamps produced by Green Scientific are designed and manufactured to achieve all of the following fundamental requirements for a spectral line source.
  • Intense emission of resonance (ground state derived) lines.
  • Narrow line width, for maximum senitivity and linearity.
  • Minimal spectral interference from continuum emission, present in the cathode.
  • Rapid warm up to produce stable long term light emission.
  • Noise free operation.
  • Long running life and a 5 year shelf life.
