Membrane Nitrogen generator

The NitroGen series NG CASTORE 3G are Membrane Nitrogen Generators. They are engineered to transform standard compressed air into a safe, regulated supply of Nitrogen with a purity up to 99.5%. An optional channel can provide up to 26 L/min of compressed, dry and regulated air.

The NG CASTORE 3G with it’s dual Nitrogen and Air outlets has been developed to meet specific requirements in term of gas, flow, purity and pressure in LC-MS applications. It can be used for the evaporation of solvents in samples being analysed.
