WEIBER nitrogen evaporators (water bath type) are typically used “to concentrate samples before analysis or to concentrate samples before a solvent exchange.When a scientist needs to concentrate a sample that’s in a volatile liquid—like acetone, acetonitrile, or methanol—a nitrogen evaporator can do the job. As a result, scientists use this technology in sample preparation in environmental, polymer science, quality control, and toxicology labs etc.Our nitrogen evaporators utilize adjustable nitrogen blow down technology allowing full control of nitrogen flow to samples, with no wasted nitrogen gas. We combined this technology with uniform efficient heat applied through water baths. This simultaneously maximizes solvent evaporation in the samples being concentrated and saves the lab money.
