N2 Membrane Generator

N2.M.25L.3G / N2.M.45L.3G

The MicroPROGEL Nitrogen Membrane Generators are engineered to transform standard compressed air into a safe regulated supply of Nitrogen with a purity up to 99.5%.
They are equipped with a Membrane with bundles of polymeric fibres designed to eliminate waste gases such as oxygen, carbon dioxide and water vapour and to retain and subsequently release only Nitrogen gas.

Product features

  • Generates Nitrogen on demand from external compressed air
  • Designed to run 24 hours a day
  • Less bulky than the Nitrogen high pressure cylinders and safe improvement due to their elimination from laboratory
  • No electrical parts
  • Low noise with no mechanical moving parts and low maintenance

Main applications

  • LC-MS
  • Solvent evaporation
