In the RapidVap N2, a stream of nitrogen or dry gas is directed downward onto the surface of the sample. This reduces the partial pressure directly over the liquid to speed evaporation and helps remove the solvent as it evaporates. In summary, the RapidVap N2 performance is maximized by increasing the sample’s surface area, increasing temperature and directing gas over the sample.
