Due to the automated feed of only a small amount of medium in the rotary flask, the conditions in the overall system are constant in terms of the parameters - temperature and vacuum. This eliminates long heating times due to the introduction of new medium. The stability of the level in the rotary flask ensures that there is no need to readjust the vacuum value in manual operation to maintain a high-performance evaporation process.
It also eliminates the time normally spent manually changing or draining the rotary flasks and receiving flasks.
All these factors contribute to the fact that the evaporation rates of an automated system are significantly higher than those of a manual solution.
