Selenium (Se) 1.5" Hollow Cathode Lamp - p/n 4151
Buck Scientific tests each hollow cathode lamp at our Norwalk CT manufacturing facility on the new Atomic Absorption spectrophotometers before shipping them out to customers. 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 Scientific sources hollow cathode lamps from a few different vendors, since over time we have learned that some manufactures do different elements better than others.
Take our word for it, we have used them all over the last 40 years!
