How to Evaporate or Concentrate Heat Sensitive Samples .

For heat sensitive samples a vacuum is used to lower the boiling point of the solvents so evaporation occurs with a minimum amount of additional heat. Bumping When a sample is placed in vacuum as a liquid, volatile samples will undergo "bumping" which is the boiling of samples resulting in solvents bubbling or splashing uncontrollably due .

What exactly is flash evaporation? - Quora

Flash vaporisation occurs because at the reduced pressure the boiling point of the liquid becomes equal to or less than that of its actual temperature. For the vapors to form, latent heat is required, which is extracted from the remaining liquid.
