N2 Membrane Generator

N2.M.25L / N2.M.25L.A / N2.M.45L / N2.M.45L.A / N2.M.60L

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.
The Nitrogen Generators versions “N2.M.25L.A and N2.M.45L.A”  can provide also a source of dry air. The Dry Air outlet can be connected to external tank, N2.25L2.TANK  or N2.50L.TANK,  where its pressure can be adjusted through the pressure regulator located on it.

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
  • Low power, low noise, low maintenance


Exclusive advantages

  • Exclusive electronic flow control that allows to generate Nitrogen with higher purity using a smaller volume of air and consequent reducing energy costs and the maintenance of external compressor
  • Continuous control of the operating parameters to maintain the system at its maximum efficiency

Main applications

  • LC-MS
  • Solvent evaporation
