	Wilkem Scientific - NITRO-GEN Generator Promotion Expires 12/31/24 The NITRO-GEN generator was developed with nitrogen evaporators in mind to provide nitrogen generation for sample concentration. The generator is lightweight and easy to set up, requiring only a source of compressed air to run. This unit is an ideal choice for labs with an in-house compressed air source. The generator uses a hollow-fiber membrane to convert compressed air to a stream of 95-99% pure nitrogen gas. The hollow-fiber membrane consists of a series of narrow, semipermeable tubes in a porous membrane. As compressed air travels through the fibers, oxygen and water vapor permeate the membrane and are vented off, leaving a steam of high purity nitrogen gas. At up to 99% purity, the resulting nitrogen gas stream can be used in a variety of sample preparation applications. NITRO-GEN 20 The NITRO-GEN 20 produces up to 20 L/min of nitrogen gas and is recommended for evaporation of up to 48 sample positions
