NG Rack 4U

Ultra High purity Nitrogen generator RACK 19” casing with integrated compressor

The High purity NitroGen series NG RACK 4U C produce laboratory high grade nitrogen for most of the laboratory applications and equipments. Designed with safety and convenience in mind, this system generates purified nitrogen, eliminating the need for inconvenient cumbersome high-pressure gas cylinders.

The NG RACK 4U C doesn’t need an external source of air because it is equipped with an internal oil-free compressor and with the optional catalyst oven it is able to remove oxygen from air to less than 1 ppm and HC pollutants to less than 0.05ppm. The available flows are: 150 cc/min and 500 cc/min. The Ultra Pure Nitrogen is mainly used to feed ICP, ELSD, GC, FTIR and is ideal as nitrogen gas supply for all kind of Laboratory and Chromatography applications.
