WebDec 20, 2012 · What does the term bumping mean in chemistry? Bumping is a process in which a solvent becomes superheated and then undergoes a sudden release of a large vapor bubble, explosively forcing liquid ... WebApr 20, 2024 · By controlling the speed of the pump, these devices can drastically reduce or eliminate the likelihood of bumping. KNF Neuberger’s new vacuum controller has an automatic feature that senses the vapor pressure of the solvent and uses that as a set point. This feature allows the user to optimize the speed of evaporation without bumping.
