VWR® Membrane Nitrogen Generators are designed to supply single or multiple LC/MS instruments with dry nitrogen at purities of 99.0–99.5%.

• Recommended and certified by all major LC/MS instrument manufacturers

These membrane generators can also be used for solvent evaporation or analytical instruments. Installation requires a minimum of 60psig of compressed air to a 63.5mm (¹/₄") or 127mm (¹/₂") inlet connection. The outlet nitrogen supply is then directed to analytical instruments. The generators require no electrical connections and the only maintenance required is to change the prefilters periodically.
