These hollow cathode lamps are produced to provide direct use without adapters in all Perkin Elmer® AAS instruments. All windows on these lamps are fully fused and contain no gassy adhesives which would drastically reduce shelf life. Totally hermetic glass seals ensure a clean fill gas and cathode for the life of the lamp and most importantly a shelf life longer than 5 years. The information provided with every lamp; giving the precise running current for each instrument type; removes the ambiguity that exists when using this type of lamp.
