A typical rotary evaporator has a water bath that can be heated in either a metal container or crystallization dish. This keeps the solvent from freezing during the evaporation process. The solvent is removed under vacuum, is trapped by a condenser and is collected for easy reuse or disposal. Most labs use a simple water aspirator vacuum on their rotavaps, so a rotavap …
Feb 25, 2021 · Evaporation is a gentle, efficient way to remove solvents and the process of rotary evaporation is a reduced-pressure distillation. It involves placing a sample within a round-bottomed flask, which is then placed in the rotovap’s heated water bath and rotated. A vacuum pump reduces the pressure above the solvent.
Dec 18, 2018 · The rotary evaporator functions on the general assumption that the boiling point of the solvent is much lower than that of the liquid surrounding it. It also assumes the compounds in the liquid are thermally sensitive; otherwise you could just boil the solvent out. A rotovap works by creating a vacuum in a rotating glass flask.
The theory of rotary evaporator revolves around the extraction of compounds. Rotary Evaporator Theory Evaporation Principle. Ideally, the rotary evaporator utilizes the evaporation principle where mixtures are subjected to temperatures which will make the mixture to evaporate. The substance to be extracted will be extracted when its boiling point reaches.
Often combined with a vacuum pump, rotary evaporators are used to remove solvents from samples through evaporation. During this process, rotary evaporators reduce the pressure within the system to lower the solvent boiling point, rotate the sample to increase the effective surface area, and heat up the solution.
The setup of a rotary evaporator. The first step is to pour the solvent mixture and the compound you want to work on in a round bottom flask. It is advisable to fill the flask less than a half if you want to get the desired results. The second step is to fill the rotary evaporator cold traps using dry ice
