Buck Scientific tests each hollow cathode lamp at our Norwalk, CT manufacturing facility on the new Atomic Absorption spectrometers before shipping them out to customers. Buck Scientific hollow cathode lamps work with all Atomic Absorption Spectrometers with the exception of PerkiElmer. All lamps have a 6 month warranty against manufacturer defect.*
*(With the exception of Selenium hollow cathode lamps, they have a 2 month warranty due to the volatility of Selenium)
Buck Hollow cathode lamps have the highest output (energy) at the lowest current for best stability and lifetime.
