The new HP Plus 500 Tower Nitrogen + HC Removal Generator produces high purity nitrogen for all major applications in analytical laboratories. Nitrogen generators eliminate the problems associated with the handling of high pressure gas tanks and reduce the cost of high purity nitrogen immediately. The HP Plus Tower series of nitrogen generators use air from a separate compressor and remove the oxygen to less than 10 ppm (hydrocarbons to 0.1 ppm is optional). The guaranteed flow rate of pure nitrogen is 500 mL/min.
