Nitrogen generators

The NG SIRIO range of nitrogen generators are designed with safety and convenience in mind.  With a variety of models to suit your requirements, providing up to 8L/min of laboratory high grade nitrogen gas, users can forget about inconvenient delivery schedules and storage of high pressure gas cylinders.

These nitrogen generators remove oxygen from air to less than 5 ppm and HC pollutants to less than 0.1ppm (if the optional scrubber is installed).  The range are available with a smart low-noise piston compressor, and all are 100% oil-free.

The Ultra Pure Nitrogen is mainly used to feed ICP, ELSD, GC, FTIR and is ideal as nitrogen gas supply for Gas Chromatography, Liquid Chromatography, Mass Spectrometry, Total Organic Carbon, Inductively Coupled Plasma Spectometry and Fourier Transform – Infrared Spectometry to name just a few applications.

Common features for the NG SIRIO NG2 generators include:

  • Easy use and installation
  • Purities up to 99.9999 %
  • Pressure up to 5.5 bar
  • Flow rate up to 8 L/min
  • Long life and 100% oil free built-in compressor
  • Reduced foot print
  • Stackable with HG and ZA
